Abstract
The strength differential effect during push-pull ~2 pct strain cycling was studied in AISI 310, α-brass, Cu, Ni, Al, Nb and Fe (Armco and Ferrovac E) at ~175 K. There is a small SD effect in Nb and Cu, none in the remaining fcc alloys, and a sizeable one in the interstitial Fe alloys. The latter were further investigated in the temperature range from 294 to 83 K; in addition values ofda/d In ε were determined in the Armco iron by stress relaxation. A direct manifestation of the SD effect is that the values determined in compression of the thermally activated stress term σ* and ofdσ/d In ε are at all temperatures in the ratio 1.14:1 to the homologous values obtained in tension. It is concluded that the SD effect is caused by a linear variation of σ* with hydrostatic stress; σ* appears to be the only plastic deformation parameter directly affected by it.
