Alloying of molybdenum
The alloying principle of molybdenum is similar to that of tungsten. All the strengthening methods used to improve the heat resistance of tungsten are basically applicable to molybdenum. There are mainly the following types: solid solution strengthening, precipitation strengthening, dispersion strengthening and composite strengthening. Solution strengthening 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...
