Title: Intensive Quenching of AISI 5160 Spring Steel Using Small Scale Laboratoty Equipment: A Progress Report

Abstract: Intensive quenching has been defined as “those quenching conditions that lead to uniform maximum surface compressive stresses” which provide maximum surface compressive stresses with correspondingly optimized distortion control. An earlier paper, described the design and construction of a laboratory system that provides sufficiently uniform interfacial heat transfer rates to be classified as an intensive quenching (IQ) system. This paper provides a progress report on the use of this system to intensively quench AISI 5160 spring steel and to summarize the initial properties obtained.

Keywords: Intensive quenching, spring steel, residual stress, fracture toughness
