Combatting undesirable NMTP formations

Whether formed during a conventional quench and tempering process, carburizing, or induction hardening, non-martensitic transformation products (NMTP) are widely considered undesirable microstructural features. However,...

A technical guide to quenching

From a quality perspective, verification of the conformance of quench requirements can be accomplished by examining a furnace chart that shows the quench trend....

Thermal triplets: PM, sintering, and case hardening

From my experience, powder metals (PM), sintering, and case hardening are three processes that could be said to be joined at the hip. More...
