The alloy of high temperature molybdenum (Mo La alloy) on high temperature performance of 1000 -- 1800 degrees and the corresponding organization and TZM molybdenum alloy. The results showed that: under the condition of less than 1400 DEG C, Mo La alloy has high strength and plasticity of the comprehensive performance, when the temperature is greater than or equal to 1400 DEG C, the tensile strength of La Mo alloy decreased obviously, and the plastic La Mo alloy also decreased significantly. As the test temperature increased, decreased the tensile strength of TZM alloy, but TZM molybdenum alloy plasticity increases, and that the La Mo alloy on the contrary. At the same time, regardless of strength and plasticity, La Mo alloy TZM alloy with the same temperature has obvious advantages. Observation shows that: the two kinds of molybdenum alloy recrystallization began at 1100 DEG C, has been extended to 1550 DEG C, and the recrystallized grains are elongated, which is obviously different from the pure molybdenum recrystallization grains under the state.
