摘要

Cast Co-5.6wt percent Cu and Co-13.6wt percent Cu alloys were subjected to severe plastic deformation (SPD) by high-pressure torsion (HPT). The HPT treatment drastically decreases the size of the Co grains (from 20 mu m to l00nm) and the Cu precipitates (from 2 mu m to 10 nm). As a result, the coercivity H_c of both the alloys radically increases. The saturation magnetization, M_s, remains almost unchanged. Thus, SPD of the bulk samples opens the way for drastic increase in the coercivity for the Co-based alloys.
