THE MICROSTRUCTURAL ASPECTS OF DEFORMATION AND FRACTURE AT ELEVATED TEMPERATURES

Abstract

A deformation hot stage metallographic facility was designed, constructed and operated successfully during the investigation of several specific problem areas. The topics that were studied include vacancy condensation pit formation on aluminum surfaces, crack propagation in aluminum polycrystals and the strain induced transformation of metastable alloy phases. Some selected experiments were conducted to study the effects of temperature and pressure on the embrittlement of aluminum and zinc by liquid metals.
