Fundamentals of High Temperature Sintering: Application to Stainless Steels and Soft Magnetic Alloys (Abstract)

By Chaman Lall, Ph.D., MPP Vice President – Technology & Applications Development Powder Metallurgy (P/M) parts are being used in increasingly demanding applications and environments which mandate optimum performance from the materials. A potent P/M approach is through the utilization of high temperature sintering. In this review, both the science base and its application to […]

Problems with Heat Treating of P/M Parts

By Howard Ferguson Anyone who buys P/M parts in the heat-treated condition or who performs heat treating in-house knows the difficulty of testing consistent properties and size control. Most commercial heat treaters base their pricing on the weight capacity of their furnace baskets and how many furnace hours it will take to process the load. […]

Problems with Heat Treating of P/M Parts (Abstract)

By Chaman Lall, Ph.D., MPP VP-Mfg. & Technology Components manufactured by powder metallurgy are being used in increasingly demanding applications and environments, which dictates that the optimum performance be obtained from these materials. One aid in the achievement of this goal is the appropriate utilization of high temperature sintering. In this review, the fundamentals and thermodynamic […]

The Effect of Sintering Temperature and Atmosphere on the Soft Magnetic Properties of P/M Materials (Abstract)

By Chaman Lall, Ph.D., MPP Vice President – Technology & Applications Development The soft magnetic properties of Powder Metal (P/M) components are essentially dictated by the level of impurities, the resultant density and the sintering practice. The focus here is on the latter, where the metallurgical structure of the product is developed. High temperature sintering […]
