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.

Solar Atmospheres of Western Pennsylvania, Hermitage, Pa., successfully vacuum heat treated the largest and longest load of nickel alloy tubing ever in a commercial vacuum furnace. They were able to preserve the brightness and cleanliness of a 45-foot-long seamless tubing while meeting extremely stringent mechanical properties.
Continue readingOne Minute Mentor: Effect of porosity on the heat treatment of powder metallurgy steels
Porosity has the greatest single effect on the response of PM Steels to heat treatment compared with conventional steels. The majority of parts have a porosity between 5 and 15 vol%, far more than is found in a typical casting. Every mechanism in press and sinter is subject to diminishing returns; i.e., compact density has a decreasing dependence on compaction pressure, as does sintering and homogenization.
