Molybdenum-rare earth oxide alloyby Izzy X. Product specialist
Molybdenum-rare earth oxide alloy (Mo-REO), also called rare earth molybdenum, is an alloy of molybdenum and rare earth element oxides, which is an oxide dispersion-strengthened alloy, similar to rare Recommended Features
- Commonly used rare earth element oxides are Y2O3, La2O3, CeO2, and Nd2O3, Sm2O3, Gd2O3, and Sc2O3.
- They are usually added in the alloy in an amount of 0.5% -3.0% (mass fraction).
- The rare earth oxide doped molybdenum is a new material that has been systematically researched since the late 1980s
- The addition of rare earth oxides can not only significantly increase the strength of molybdenum, improve the high temperature resistance of molybdenum
- It is an excellent high temperature structural material.
Review on Molybdenum-rare earth oxide alloyThe molybdenum-rare earth oxide alloys are classified as follows:
Dispersion strengthened alloy
Unit system: Mo-La2O3, Mo-Y2O3, etc.
Multivariate: Mo-La2O3-Y2O3, Mo-Y2O3-Sc2O3
Precipitation strengthening + dispersion strengthening alloy:
TZM-La2O3, TZM-CeO2, TZM-Y2O3
TZC-CeO2, TZC-La2O3, TZC-Y2O3, TZC-CeO2-Y2O3
ZHM-Y2O3, ZHM-La2O3, ZHM-CeO2
At present, the most important molybdenum-rare-earth oxide alloy is Mo-La2O3, which systematically studies the fracture initiation, high-temperature strength, ductile transition temperature (DBTT), and the properties of the foil. Developed Mo-La2O3 (0.3-1.0%) high temperature resistant molybdenum, which is widely used in high temperature furnaces. This alloy has a higher use temperature than pure molybdenum and higher processability than TZM Molybdenum.
