Abstract
The effect of cold work on the mechanical properties and microstructure of an fcc Fe-Ni-Co-Cr-Mo alloy is discussed. In samples deformed up through 20 pct, strengthening is attributed to an increase in dislocation content. Greater deformation (48 and 75 pct) results in the formation of deformation twins which increase in density with cold working. The deformation twins contribute to the high yield strength (0.2 pct offset) of 154 kg/mm2 which is attained in this alloy upon cold working (75 pct elongation). This hardening mechanism is in contrast with that reported to be operating in a similar fcc Co-Ni-Cr-Mo alloy in which strengthning is attributed to the formation of a deformation-induced fine hcp epsilon phase.
