Physicochemical zog ntawm molybdenum alloys

Molybdenum alloys, raws li cov hlau refractory, muaj kev ua haujlwm kub ntawm 1100℃txog 3320 degree. They possess advantages such as low density, low coefficient of thermal expansion, high elastic modulus, good high-temperature creep resistance, and weldability. Txawm li cas los xij, lawv tsis muaj zog ntawm qhov kub thiab txias thiab nthuav tawm oxidation hnyav ntawm qhov kub thiab txias.

Ntawm tag nrho cov ntsiab lus alloying, tsuas yog rhenium (Re) zoo cuam tshuam rau qhov qis - kub plasticity ntawm molybdenum. Ntxiv 5% mus rau 50% Re tuaj yeem txhim kho qhov qis- kub plasticity, lub zog, thiab weldability ntawm molybdenum alloys, txo brittleness tom qab recrystallization, thiab txhim khu thermal shock resistance. Molybdenum alloys tsis tshua muaj embrittlement nyob rau hauv lub tshuab nqus tsev los yog inert gas tej yam kev mob.
