The International Titanium Association, Northglenn, Colo., announces that the Titanium 2016 conference and exhibition will focus on the global titanium industry. The event will be held September 25th - 28th at the J.W. Marriott Desert Ridge Golf Resort in Scottsdale, Arizona, providing nearly 1000 attendees with valuable insights, timely information and networking opportunities in the global titanium industry.
The conference will host numerous speaker sessions to address titanium business trends and manufacturing technology innovations, along with presentations by a number of accomplished individuals. Special guest speakers include Richard Aboulafia, vice president of analysis at the Teal Group; Allan McArtor, the chairman and chief executive officer of Airbus Group Inc.; award-winning author, journalist and international correspondent Robin Wright; American inventor and electrical vehicle pioneer William Morrison (Chip) Yates, who serves as vice president of marketing for Norsk Titanium; and pilot, author and photographer Brian Shul, one of only 93 men in history to fly the legendary, titanium-intensive SR-71 spy plane, the fastest jet ever built.
Henry Seiner will deliver a presentation on "Trends in the Defense Market: A Titanium Perspective," as a member of the World Titanium Industry Demand Trends segment. Henry will address aerospace, marine and land-based titanium applications and their market drivers. Seiner will frame his remarks in the larger scope of defense budgets and increasing global tensions. China and United States continue to have the world's two largest defense budgets. However, the gap is closing as the U.S. defense budget declined for the fifth consecutive year in a row and its ratio of outspending China has dropped from 10:1 to 3:1 in the last decade. The decline in value of the euro, the ruble and the price of oil has caused a shake-up of ranking for the remaining top 15 military spenders.

Newage traverse hardness testing system is fast and precise
August 17, 2016
Source:
Newage Testing Instruments, Southampton, Pa., introduces the MT91 Automatic Microhardness Traverse Testing System, which offers testing speed as fast as six seconds per test cycle and a precise Rockwell type testing method that requires no manual interpretation of the impression.
The MT91 measures hardness based on depth of penetration, rather than an optical system that determines hardness based on impression size. Tasks that once took hours now take only minutes, and individual test cycles can be completed in just six seconds.
Case depth comparison is considerably easier using the MT91 system than a traditional optical system. Operators can quickly and easily set up complicated staggered traverse procedures with the graphical utility set up utility. The MT91 then performs the traverse routine accurately and repeatedly and calculates the sample's case depth. Up to 24 traverses can be setup as part of a single procedure.
The modular Newage MT91 System is a cost-effective solution for applications that require advanced microhardness functionality, such as complex case depth traverses. The system consists of an MT91 microhardness tester with video camera, combined with a personal computer, a motorized X-Y axis positioning table, and Newage's proprietary C.A.M.S. (Computer Assisted Measurement System) software.
The system's video camera views and defines test measurement locations and traverse procedures. The C.A.M.S. software operates the test head and motor control system to accurately position test samples and perform measurement cycles. Compared to automated optical microhardness testers, the MT91 is less dependent on surface conditions. It has no difficulties with dark spots or varying light levels on the test samples that can occur with optical systems. It also can be used to test etched parts or measure surfaces prepared to 400 grit polish.

Purdue receives grant to design strong and ductile aluminum
Source:
Purdue University, West Lafayette, Ind., announces that ASM member Prof. Xinghang Zhang has been awarded a $450,000 grant from the Dept. of Energy to investigate methods for increasing the strength of aluminum alloys.
"One of the major issues with aluminum alloys is that strength is much lower than steels," he said. "Aluminum is ductile, but it's very soft." The research will be done at the microscopic level by using a transmission electron microscope that can reveal the atomic arrangement inside aluminum. The School of Materials Engineering recently acquired an advanced transmission electron microscope for the deformation project and future research.
"This grant allows us to explore fundamental science on mechanical behavior of nanotwinned aluminum and could eventually lead to the design of high strength and ductile aluminum alloys," he said.
Nanotwinned metals can be used in many applications because they simultaneously demonstrate high strength and high ductility, characteristics usually thought to be mutually exclusive. Deformation mechanisms describe how a metallic material can change its geometry under external force.
"You have to really look at why an aluminum alloy is soft and what you have to do to make it much stronger and remain ductile," Prof. Zhang said.

One Minute Mentor: Effects of Stress Relieving Temperature on Corrosion Resistance of Stainless Steel
August 12, 2016
Source:
Although stabilized alloys do not require high-temperature annealing to avoid intergranular corrosion, the stress-relieving temperature exerts an influence on the general corrosion resistance of these alloys.
The graph shows the effect of stress relieving for two hours at various temperatures on the corrosion rate of type 347 stainless steel in boiling 65% nitric acid. The corrosion resistance of type 347 in boiling nitric acid is better when the material is treated at 1500 to 1600°F than when treated at 1200 to 1300°F. The 1200 to 1300°F stress relief may be promoting the formation of a small quantity of chromium carbides as a result of free carbon not previously tied up as niobium carbides.

Classic Article: Continuous Carburizing by Gas
Source:
Despite the growth of alloy steels and special means of surface hardening, the ancient art of carburizing steel remains one of the fundamental operations in the manufacture of machine parts. It retains its popularity because it enables the workman to start with a material that can be easily machined, and end with an excessively hard and desirable surface for resisting wear, retaining ductile metal underneath with sufficient strength and shock-resisting properties to stand up to severe duty.
As is well known, most carburizing is done by the time-honored method of packing the steel with carbonaceous materials in suitable containers, covering it in such a way as to prevent infiltration of furnace gases, then raising the temperature to a suitably high point, and holding it there for some hours, depending upon the depth and character of case desired. Carburizing by this means is dependent on a number of factors, many of which arise from the character and uniformity of the compound; great care must therefore be vised in handling the compound to obtain satisfactory results. At best, there are still many variables that are hard to control and results that are difficult to explain. It has been felt for many years that this metallurgical process is too cumbersome and dirty to fit in well with modern manufacturing practice. To those who have studied the matter, it seemed that the desired improvement could be had in a process for carburizing with an externally prepared gaseous atmosphere. Such an atmosphere could be clean, of uniform composition, easily controlled, always fresh and theoretically desirable.
