What is molybdenum alloy comprehensive strengthening mechanisms？
The solid solution strengthening and carbide strengthening, carbide strengthening and enhancement ODS, ODS strengthening and enhancement bubbles, and their variety combined with each of these alloys are called multicomponent alloys.
Molybdenum alloy between the various strengthening mechanisms are closely linked, to strengthen the role of trace elements mainly in the 1100 ~ 1300 ℃ temperature play a role, when the temperature rises again, it will fail;
And carbide dispersion strengthening effect on the 1400 ~ 1500 ℃ is most evident in the 1500 ~ 1800 ℃ softening of carbides, instability, high melting temperature for significantly enhanced the effect of rare earth oxides, higher than 2000 ℃, the rare earth oxide, material begins to soften, and doped aluminum, potassium, silicon bubbles enhance the effect.
People have been in the pursuit of higher performance materials, comprehensive strengthening can achieve further performance improvement has become a hot research and development molybdenum alloy.
