THE STRENGTH AND PLASTICITY OF ANISOTROPIC METALS.
Abstract
Sheets of the magnesium alloys AZ31B, HK31A, and ZE10A in several different tempers were tested in tension and determinations were made of the ratio of width-to-thickness strains. Fracture appearance is explained on the basis of anisotropy in plastic flow, and implications for developing texture- hardening effects in these alloys are discussed. Titanium sheet of commercial purity (RC-70) and an alpha-titanium alloy (2-1/2 Sn 5 A1) were tested in tension and plane-strain compression. Strain ratios of R < 1 in the RC-70 sheet eree related to an unexpected texture with a strong concentration of (000) basal poles along the transverse direction. The low R values were responsible, in turn, for a texture softening in plane-strain compression. In the 5 A1:2 1/2 Sn alloy a strong (000) concentration near the sheet normal was responsible for higher R values and the observation of texture hardening in planestrain compression. (Author)
