Advances in Quenching- A Discussion of Present and Future Technologies

摘要

This paper illustrates the numerous advancements that have been made in quenching over the past several years, bringing quenching from a black art (Figure 1) to an advanced science. A review of the mechanism of quenching, and the causes of distortion and residual stresses will be discussed. In addition, advances in quenching, such as new oil and polymer quenchants, alternative quench methods (gas quenching, induction hardening) will be discussed. New advances in modeling quenchant flow using computational fluid dynamics and modeling distortion, as function of quenchants and heat transfer will also be discussed.
