TOPIC: Metrological traceability of the unit of length: from ancient to modern times Metrological traceability provides the connection and accuracy for measurements made through the world to the same system of fundamental SI units. From the realization of the units, typically done in a national laboratory such as NIST, through calibration laboratories and onto the manufacturing floor, metrological traceability supports the global economy and underpins the interchangeability of parts. This talk will discuss some aspects of metrological traceability and will follow the history of the unit of length from ancient to modern times. This meeting is part of the 2017-2018 Inter-Society Technical & Social Event Series, hosted by SAMPE, ASME, ASM and AWS.

Intertek Transportation Technology working with the DoE and several national laboratories on collecting “real world” data on a variety of alternative energy vehicles. Testing includes vehicle performance, durability, and operational costs helping consumers and the automotive industry better understand how vehicle technologies intended to reduce the consumption of petroleum actually perform in the streets. Testing begins with baseline determination and then the vehicles are driven approximately 200,000 miles over 3 yrs, collecting data on the overall performance of the vehicle and its innovative technologies. Refueling, maintenance and repair costs are tracked to ascertain the real world performance and the cost of ownership. This combination of real-world and laboratory analysis provides a more comprehensive understanding of what a customer and the industry can expect once they choose one of these alternative energy vehicles. The emergence of autonomous vehicle testing will also be discussed as part of the presentation and review of the new American Center for Mobility (ACM) proving grounds. https://avt.inl.gov/vehicle-type/all-powertrain-architecture

Outer space technology and exploration have reached a tipping point, so that mining and mineral processing in outer space is now a certainty and not a dream. Several competing private companies worldwide are well on the way to building spaceships to land on the Moon, capture asteroids, and eventually extract the resources for volatiles, rare earth metals, and Helium-3. How and why are the Moon and asteroids and their resources of interest to private space industry companies? Why are the Moon and asteroids viewed as a potential lucrative business venture? What are the unique technical challenges for private companies for outer space travel and outer space mining? The primary international law regarding resource extraction on the moon and asteroids is the outdated 1967 Outer Space Treaty. How will private companies stake their mining claims in outer space and what are some of the legal battles that are expected to ensue? What laws are countries passing to deal with private space travel and mining? How are governments working with private companies and competing with private companies to achieve this “moonshot”? This meeting is part of the 2016-2017 Inter-Society Technical & Social Event Series, hosted by SAMPE, ASME, ASM and AWS.

Under conditions of static and dynamic loading to high pressures or stresses, it can be critical to quantify the strength of a material and it is well understood that material microstructure controls properties like strength. It is also expected that microstructures, particularly for many important structural metals like iron and titanium, are evolved or modified in significant ways when subjected to high stresses. These modifications include microstructural refinement due to twinning, significant storage of plastic work within grains, and even phase change. Therefore, it follows that the strength of the material under stress is dependent on the microstructure evolved under stress. This is problematic, as until recently the materials science and physics communities have been limited to post mortem interrogation of materials exposed to high stresses and little is quantified about the actual microstructures under load. Current predictive capabilities for strength under high stress utilize the known microstructures prior to loading and under moderate stress conditions. Post mortem investigations of material subjected to extremes of stress indicate that this may be problematic. Here, recent work on titanium and zirconium metals that includes the use of current light sources, such as the Advanced Photon Source at Argonne National Laboratory, will be presented to discuss quantification of structure at high stresses. This will be related to on-going efforts at Los Alamos National Laboratory to develop phase-aware, predictive modeling capabilities for material strength at pressure.

Fiber-reinforced composite materials are used in a number of engineering applications at Sandia National Laboratories in support of our national security mission. The Polymer Processing Laboratory has expertise and capability that supports composite design, fabrication, prototyping, and limited production for DoE and DoD Programs. This includes design, material selection, tooling production, fabrication (wet layup, pre-preg layup), curing, and final/finish machining. We also partner with polymer physicists, polymer material characterization specialists, and stress analysts to understand performance of composite structures in thermal, mechanical, and other relevant environments. This presentation will describe our equipment and capabilities, and will then focus on examples of recent applications. Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.
High Speed Infrared Temperature Measurements on Composite Laminates During Low-mass, Low-velocity Impacts
April 18, 2017 | Chama River Brewing Co, 4939 Pan American West Freeway NE
High speed infrared imaging is being implemented to assess the thermal profile and energy transfer from an impactor onto a solid woven carbon fiber re-enforced plastic. Solid laminate composite specimens were impacted with both blunt and sharp tools while either the front or back surface is monitored with a high frame rate infrared camera. The post impact damage was evaluated and characterized using digital radiography and computed tomography techniques. Matrix cracking and delaminated plies are the two primary failure mechanisms. This presentation explores the energy balance equations within the elastic-plastic regime and describes the challenges of collecting viable temperature measurements for composites under transient loading. Measured temperature increases reveal there is a correlation to relative loss of the composite's transverse stiffness that is directly related to the energy absorbed by the plies. Composite layup configuration and last ply orientation with its influence on failure will also be discussed.

Astronomers have recently been fascinated by a newly discovered phenomenon known as Fast Radio Bursts, or FRBs. FRBs are brief but powerful bursts of radio waves, lasting only a few milliseconds, but detectable with large radio telescopes. Although first identified about a decade ago, catching these bursts in the act is rare, and only about 20 have been seen to date. The signal properties suggested an origin far outside our own galaxy, but otherwise not much was known about where they come from or what might cause them. Late last year, my collaborators and I used the Very Large Array in New Mexico to observe an FRB; for the first time, this let us unambiguously determine exactly which galaxy the signal came from. This has answered some questions about FRB origins, but raised many others! In this presentation, I will review the scientific and technical developments that led to this result, and discuss future directions in our efforts to solve this astrophysical puzzle. A common theme throughout is unexpected or serendipitous discovery enabled by new technology, and the ongoing exploration of the time domain as the new frontier in astronomy. Dr. Paul Demorest is an associate scientist at the National Radio Astronomy Observatory where his primary research focus is on observations of radio pulsars and the analysis and instrumentation required to conduct the observations. His development of specialized instrumentation has enabled the capability to observe pulsars with very high timing precision. With these methods of characterizing the interstellar medium and pulsar signals, a unique view of the structure of the ionized interstellar medium is revealed.

Introduction to Shape Memory Alloys Don Susan, ASM Fellow. Metallurgy and Materials Joining Department Sandia National Laboratories, Albuquerque, NM Shape memory alloys (SMAs), such as NiTi Nitinol, exhibit both shape memory effect and superelasticity. These "smart materials" enable unique applications as sensors and actuators. The behavior of shape memory alloys will be introduced with the aim of simplifying the concepts involved. The talk will include a fun & easy demonstration, an overview of SMA concepts, and a summary of recent research at Sandia. In the Sandia research, alloying NiTi SMAs with Pt, Pd, or Hf provided access to higher transformation temperatures. Several alloys were processed via arc melting in a laboratory button melter followed by homogenization heat treatment. The alloys were characterized using differential scanning calorimetry, optical microscopy, and SEM. For select compositions, the thermomechanical properties were determined using tensile coupons. Ultimately, both the shape memory effect and superelasticity were demonstrated within the desired temperature range for these alloy systems. Speaker Bio: Don Susan is a Principal Member of Technical Staff at Sandia National Laboratories and a member of the 2016 class of ASM fellows. Don's research interests involve materials joining including welding, brazing, and soldering, as well as research on the metallurgy of precious metal alloys and soft magnetic alloys.
