Abstract

In order to further improve the usage temperature of high temperature titanium alloy, two kinds of near α titanium alloy ingots with Er and Re were prepared. The influences of Er and Re on the alloy under two kinds of forging conditions, namely, β phase region and near β phase region were investigated by scanning electron microscopy (SEM) and tensile test. The results showed that under the forging in β phase region both basket-weave microstructure and there are obvious beta grain boundaries in the structure. The equiaxed α of the alloy containing Re is more obvious after forging in near β phase region. The overall performance was better when forging in near β phase region than in β phase region, the comprehensive properties of the alloy that containing Re was better than that of Er.
