Abstract:

The isothermal transformation diagram for high carbon M-2 tool steel was determined for material austenitized at 2200F for 1 hour. The austenitic grain size was identified as ASTM No. 9 and there was 21 volume percent of undissolved carbides at the austenitizing temperature. The diagram was double-nosed with little transformation occurring between 700 and 1150F. The curve representing the start of precipitation of proeutectoid carbides is included on the isothermal transformation diagram and the M sub s temperature was found to be 420F. Author
