查询词典 precipitation hardening

When the precipitate is not yet coarsened as shorter in rupture life, the precipitation hardening effect may be intensified by the increasing of precipitate, so that the high temperature strength may be raised by the increase of W content, while the precipitate may coarsen markedly and the precipitation hardening effect may reduce on heating for sufficient long time.
