Abstract : The dislocation substructures developed in AISI 304 stainless steel, Mangalloy (Fe-14% Mn - 3% Ni) and E-Brite 26-1 (Fe-26% Cr - 1% Mo) have been studied as a function of various warm working conditions. Warm working studies were performed in the range 0.4 to 0.6 T sub m (T sub m is the melting temperature of the alloy) and at strain rates from 0.01/s to 6.3/s. The dislocation substructure (which usually consisted of subgrains) was captured by rapid quenching after torsional deformation and examined using thin film transmission electron microscopy. The room temperature compression yield strength of the alloys investigated was determined after warm working and quenching. (Modified author abstract)
