Jesse Ondersma, from Intertek, will give a presentation on battery failure analysis

MIke Kozal, VP of Engineering at Pridgeon and Clay, will give a talk on "Educating the Educated - A Skilled Worker Shortage." Today our businesses must deal with the aging of those skilled tradespeople, and the large deficit of young new talent willing to take the baton and advance what we have built thus far. The average age of our skilled workforce is 59. There are few vocational programs. If we do not act to provide a new, solid “hands-on” work force, we are faced with a catastrophic melt down of industry. This presentation is intended to help facilitate sharing ideas about what seasoned professionals can do to share knowledge by teaching and coaching the next generation.

The timeline, contributing factors, and costs of this complex web of technical, political, and educational failures will be outlined. We'll look at the roles of various parties who contributed to the investigation, including: Michigan Radio, The American Civil Liberties Union, Pediatrician Dr. Mona Hanna-Attisha, and a team of water experts from Virginia Tech hired by a citizens' group. Was the root cause really a simple failure to meet specifications? The Flint water crisis has brought to light the fact that many other cities have lead drinking water pipes in current use. This presentation is based on author's presentation for the Materials Science and Technology Conference in Salt Lake City, Utah, at the end of this October, in the Failure Analysis Symposium.

Lightweighting, like engineering, can be both a verb and a noun – an action and a result. As such, it is an important technical enabler for all manner of consumer, industrial, and durable goods by improving mobility or portability – and more broadly, quality of life. Among metals, magnesium (atomic weight 24) is one of many possible lightweighting alternatives to steel/cast iron (atomic weight 56) and aluminum (atomic weight 27). The "Development of a Magnesium-Intensive Engine" examines a multi-year, multi-million dollar precompetitive applied research program addressing the Corporate Average Fuel Economy (CAFE) mandate of 54.5 miles per gallon by 2025. Jointly led by GM, Ford, and Chrysler, Peter served as Technical Administrator and Consultant, guiding the collaboration of a team representing over 50 suppliers, universities, and national laboratories. The "Development of a Magnesium-Intensive Engine" takes a comprehensive systems-level "atoms to autos" approach, revealing many aspects of materials design and selection from alloy development and characterization through engine design, testing, and evaluation.

Materials science is often described as the understanding and application of the relationships between processing, structure, and properties. A critical link in connecting these concepts is characterization of materials structure at the micro- and nano-scales. Historically, optical and electron microscopy have been the workhorse techniques for carrying out this microstructural characterization. With the push towards more nanostructured materials and devices, the need for higher resolutions and the capabilities to characterize over 3-D volumes has become more critical. In addition to enhanced scanning electron microscope (SEM) resolutions, now in the range of 1nm, the ability to section, deposit, and characterize small volumes of materials using a focused ion beam (FIB) now allows a wide range of characterization and processing to be carried out at the nano-to micro-range. The integration of the FIB columns with advanced SEM's results in flexible instruments that allow a very broad range of experiments and manufacturing at nano- to micro-scale. Specifically, these dual-column FIB's are often combined with a range of auxiliary facilities such as gas injection systems, nanomanipulators, electron backscattered diffraction (EBSD), energy dispersive x-ray spectroscopy, various detectors, and a wide variety of stages that allow even greater flexibility for advanced studies. While dual-column FIB's are best known for site-specific transmission electron microscopy (TEM) sample preparation, the ability to precisely remove and add material, as well as move small sections and components, increase the capabilities of these instruments. This talk will begin by briefly reviewing some basic examples of the process, structure, property triangle, and will continue with the basic configuration of dual-column instruments. Then using an example of site-specific TEM sample preparation, the general functionalities of the primary components will be demonstrated. Following this is number of case studies will be presented that illustrate the flexibility of dual-column systems. Finally, potential artifacts associated with ion beam damage will be discussed.

The presentation will focus on cataloging and using physical indicators of damage from electrical arcing, resistive heating and exposure to heat and fire on brass artifacts from fire scenes, including automotive fires. Case studies where damaged brass artifacts were processed as part of an origin and cause determination will be used to illustrate the principles of failure analysis in fire investigation. Examples of brass artifacts include gas appliance connectors, valve bodies, plug blades, and receptacle buses.

Have you ever thought that the typical design, development and manufacturing process was overburdened with irrelevant procedures while at the same time missing important features? The speaker's 45 years of experience of managing many such programs has led him to that conclusion. We'll pick the project development process and give some examples. One example is the program review - what is its intent and what does it accomplish? What is usually missing is a good dose of common sense, and this presentation gives a number of examples of how to use that good old-fashioned common sense that everyone has in the product development process. It won't be all-inclusive, but is intended to spark the imagination of the listener so they too, can apply common sense principles to engineering, manufacturing and quality processes.

Acoustic Emission (AE): AE uses transient elastic waves generated by various processes, including plastic deformation, crack propagation, erosion, corrosion, impact, and leakage to monitor active damage processes in a material or structure. The AE method requires the test piece or structure to be under load, and that not only active damage processes are detected. Applications in materials research and structural integrity monitoring using this cost effective and powerful method will be described.
