Molybdenum Yttrium Alloy Wire Processes As Follows:
Molybdenum dioxide powder is immersed in the yttrium nitrate solution, soaking, drying, were mixed after the temperature of 800 ~ 1000 ℃ for hydrogen reduction to obtain a rare earth doped yttrium oxide of molybdenum oxide powder;
The molybdenum powder doped well under pressure in 160 ~ 200MPa isostatic pressed into bars, and then sintered at high temperature, and finally through the swaging and drawing, made of molybdenum wire.
Preparation of molybdenum yttrium alloy wire
Molybdenum is added in the rare earth oxide yttria, billets made by powder metallurgy method, after the swaging and stretching processing, yttrium alloy wire made of molybdenum.
The results showed that: wire annealed at 1750 ℃ for 30 minutes to form a long and large recrystallization, its tensile strength and bending performance is much better than the pure molybdenum, good room-temperature toughness.
