Many of you are likely to have heard Harb Nayar, president of TAT Technologies, LLC, expert in all things sintering, explain innovative ways to produce heat treated products. But perhaps you are wondering, how would “atomised prealloyed steel particles,” that is micro-ingots, work within the realm of heat treat?

This Heat Treat Today Best of the Web feature is pulled from a powder metallurgy (PM) whitepaper in which Harb Nayar describes the PM background, processes, and application in more detail. Read his detailed whitepaper, “The micro-ingot route: A variant of the PM process that could offer new opportunities for the PM industry,” on the web, or download the free PDF.

An excerpt: “This micro-ingot approach, when combined with newer heat treatment technologies, can lead to a redesign of the current macro-ingot products that can potentially help to reduce the weight of the finished product resulting in a longer product life span.”
