TZM Molybdenum target alloy strength at high temperature than other molybdenum materials, high strength, wear better, molybdenum alloys in the crowd. TZM molybdenum alloy recrystallization temperature than pure molybdenum high 300-400 ℃. TZM molybdenum alloy is widely used in hot runner, thermoforming molds and other fields
200 molybdenum lanthanum alloy material with advantages over pure molybdenum
Molybdenum high pure molybdenum has a higher recrystallization temperature. High temperature ductility better than pure molybdenum.
201 high temperature molybdenum alloy TZM molybdenum alloys and high Tungsten eletrode performance
By TZM (molybdenum lanthanum alloy) and TZM molybdenum alloys in 1000 ~ 1800 ℃ high temperature performance and corresponding organizational studies. The results showed that: the case of less than 1400 ℃, lanthanum molybdenum alloy has high strength and ductility combination of properties when the temperature is higher than 1400 ℃, the molybdenum alloy tensile strength decreased lanthanum, molybdenum, lanthanum alloys also have significant ductility decreased. With the temperature increase test, TZM alloy reduced tensile strength, ductility but elevated molybdenum alloy TZM, which is opposite and molybdenum lanthanum alloys. Meanwhile, regardless of strength or ductility, TZM molybdenum alloy compared to the same temperature lanthanum alloys have a distinct advantage. Organization observations show that: The two molybdenum alloy recrystallization starts at 1100 ℃, has been extended to 1550 ℃, and its elongated recrystallized grains are showing the organization, which is significantly different from pure molybdenum recrystallization state equiaxed grains
Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.
