Ipsen, Cherry Valley, Ill., has expanded its field service capabilities to include ultrasonic wall thickness testing for vacuum furnaces. The test helps customers verify the integrity of their chamber and determine its remaining lifespan.
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

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.

Air Products, Lehigh, Pa., has announced a multi-billion-dollar plan to build a new net-zero hydrogen energy complex in Edmonton, Canada. The $1.3 billion (CAD) net-zero hydrogen production and liquefaction facility expected onstream in 2024 will accelerate the transition to a cleaner, more sustainable energy future.

During sintering, metallurgical bonds form between powder particles. Strength, ductility, toughness, and electrical and thermal conductivities increase with increasing density. If different materials were blended together, interdiffusion could promote the formation of alloys and intermetallic phases. As a consequence of the density increases, size decreases.

Ferrous alloys are often produced by mixing graphite with iron powder to form a steel or stainless steel. This allows for using lower pressures during compaction of the softer iron powder, which does not contain carbon.
