ABRUPT DECREASE IN TITANIUM PLASTICITY AT HIGH TEMPERATURES,

Abstract

An investigation showed that an abrupt drop in plasticity is observed in vacuum-treated titanium in the 300-500C interval. In titanium saturated with hydrogen, hydrogen brittleness is superimposed on this drop at low rates of stretching. The hydrogen brittleness is caused by directional diffusion of hydrogen toward imperfections of the crystal structure and toward grain boundaries. The effect of hydrogen on titanium properties in this interval of temperatures is similar to strain aging. (Author)
