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