Review on Alloying of molybdenum

Solid solution strengthening includes the addition of trace elements and high content elements.
The trace element solid solution strengthening method mainly refers to adding a trace amount of Ti, Zr, Fe, Mn, La, B and other alloy elements for solid solution strengthening to improve the performance of molybdenum. When trace elements are added, a certain amount of carbon is often added to the alloy. It is the alloy elements and carbon that form carbide dispersed particles to strengthen the strengthening effect.
High content element solid solution strengthening
The elements that improve the binding force between atoms of the molybdenum alloy and form a continuous solid solution are tungsten, tantalum, and rhenium. Tantalum and rhenium are scarce metals, the main alloy of solid solution strengthening with high content of elements is Mo-W alloy. The strength of the alloy increases with the increase of tungsten content, but its thermal deformation performance deteriorates with the increase of tungsten content, so the content of tungsten should not exceed 30%. The alloy has a very low ductility-brittle transition temperature due to the "rhenium softening effect". Commonly used molybdenum-rhenium alloys are Mo-5Re, Mo-41Re and Mo-50Re.
The solid solution strengthening alloy elements are mainly Ti, W, Re, and the typical alloys are Mo-0.5Ti, Mo-30W, Mo-41Re. The recrystallization temperature is 1100-1300, 1200, 1200-1300.
