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.
Continue readingDevelopment of a Residual Stress Standard
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

The heat released at the part surfaces affects porosity in many ways. Surface porosity increases the roughness which slows down the speed of the cooling medium that is removing heat from the part surfaces. The suction effect exerted by the hot gas present inside porosity contracts itself during cooling, which suctions the vapor bubbles originating from the quenching liquid.
