Improve ways to enhance tungsten materials

Tungsten alloy materials use of high temperature materials, simple method to increase the use of solid-solution strengthening effect is not high temperature strength of tungsten. However, on the basis of solid-solution strengthening further dispersion (or precipitation) hardening, can greatly improve the high temperature strength to ThO2 and precipitation particle dispersion strengthening effect HfC best. In about 1900 ℃ W-Hf-C series and W-ThO2 alloys have high temperature strength and creep strength. In the recrystallization temperature of Tungsten alloys used below, take temperature hardening methods to produce strain hardening is an effective way of strengthening. Such as fine tungsten wire with high tensile strength, total processing deformation rate of 99.999%, a fine tungsten wire having a diameter of 0.015 mm, tensile strength at room temperature up to 438 kg / mm.
