【Abstract】 The microstructure characteristics by solution and precipitation strengthenings for Nb-W alloy are introduced in this paper. It is found that the solution plusing aging treatments make carbide precipitates fine and uniform. Tensile test indicates that the strengthening effects are notable at room temperature and high temperature. All kinds of possible strengthening mechanisms and their influence are also discussed.更多还原
