The most important function of alloying elements in heat treatable steels is to increase hardenability, whether for quench and tempering or sinter hardening. Adding copper increases both hardness and tensile strength in the sintered condition.

Seco/Vacuum, Meadville, Pa., has sold two new Vector single chamber high-pressure quench vacuum to the Australian defense industry through HTA. These will go to the Melbourne and Sydney commercial heat treatment facilities to provide expanded processing capabilities.

Amkor Technology, Incheon, Korea, has demonstrated three new types of thermal interfacial materials (TIM) with high thermal conductivity (> 20W/mK). Workability and reliability test results for metal sheet TIM (60W/mK), graphite sheet TIM (24W/mK), and silver (Ag) sintered TIM (50W/mK) have been presented in a new paper.

Accurate Brazing, Greenville, S.C., has received the Nadcap merit accreditation for heat treating at its Pelham Road facility. The accreditation is for demonstrating an ongoing commitment to quality by satisfying customer requirements and industry specifications.

Surface Combustion Inc, Maumee, Ohio, has shipped a new ion nitriding thermal processing furnace system for Watervliet Arsenal. This allows them to add control to the product supply chain.

In the past ten to fifteen years, significant progress toward the understanding and management of residual stresses in metallic structure has been made under the auspices of numerous Metals Affordability Initiative (MAI) projects, Small Business Innovative Research (SBIR) projects, USAF program funded projects, and many others. In January 2020, the ASM International Technical Committee on Residual Stress formed a subcommittee on residual stress standards development, whose goal is to promote the development of standards and specifications for the measurement, modeling, understanding and management of residual stress
