Na. Akhmadeev et al., FORMATION OF SUBMICRO GRAIN-STRUCTURE IN COPPER AND NICKEL BY EXTENSIVE SHEAR DEFORMATION, Russian metallurgy. Metally, (5), 1992, pp. 86-91
A submicro grain structure was obtained in solid copper and nickel spe
cimens by extensive deformation using equichannel skew pressing follow
ed by low-temperature annealing. The structure and microhardness of sp
ecimens after intensive deformation and annealing in the range from 50
to 500-degrees-C were studied.
