Abstract : The effects of short quench interruptions on the percentage retained austenite and the hardness and microstructure were investigated for AISI 52100 steel. Effects were observed for two starting microstructures: an as-received, spheroidize-annealed material, and a fine-grained, warm rolled material. Results indicate that retained austenite and hardness were independent of the quench interruption temperature. The warm rolled material had a higher percentage retained austenite as well as a higher hardness for all quench interruption temperatures. This is attributed to a finer starting microstructure and the retention of refinement throughout the heat treatment process. Evidence of preferred orientation was found in the case of the material showing prior warm rolling.
