Studies on the Warm Working Characteristics of Alloys.
Abstract
EL 304, STRAIN RATEThe deformation of AISI type 304 austenitic stainless steel, Mangalloy (Fe-14% Mn-3%Ni), E-Brite 26-1 (Fe-26%Cr-1%Mo) ferritic stainless steel, 1018 steel containing 0.5%W, and 7075 aluminum has been studied in torsion over a range of deformation conditions representative of 'warm working' (0.4-0.6Tm, where Tm is the melting temperature of the alloy at strain rates from 0.01/s to 6.3/s). The results obtained at the various temperatures and strain rates were analyzed taking into account atom diffusivity and elastic modulus plotting the data as diffusion compensated strain rate versus the modulus compensated stress for each alloy. A clear separation in strength characteristics between the various alloys was obtained when the contribution from dislocation pipe diffusion was included in the diffusion coefficient indicating that diffusion along dislocations is important during warm working.
