SHEAR STRENGTH OF TWELVE GROSSLY DEFORMED METALS AT HIGH PRESSURES AND TEMPERATURES.

摘要

The shear strength of grossly deformed tungsten,germanium,nickel,beryllium,uranium,copper,gold,silver,aluminum,magnesium,bismuth,and tin was measured in an opposed anvil shear apparatus at pressures up to 150kb at 27C,and for gold,silver,and copper to 900C. The shear data agree with independent strength measurements at low pressures,but differ significantly from high-pressure shear-strength measurements made by other investigators. The data on the noble metals also fit a simple empirical formula relating the temperature and pressure dependence of the shear strength. (Author)
