Abstract

A specially developed method of heat treatment has made it possible to study the effect of grain size on the yield stress and the deformation stress of 36NKhTYu alloy which has undergone practically complete discontinuous decomposition. The well-known Hall-Petch equation is shown to be completely applicable. The parameters σ0 and K of this equation are determined and compared with those for material aged by the mechanism of continuous precipitation.
