- the rare earth element RE has strong affinity for oxygen, sulfur, nitrogen and hydrogen, so its deoxidation, desulfurization, removal of hydrogen and nitrogen are strong, and RE is the surface.
- the active elements can be concentratedly distributed at the crystal interface to reduce the tensile force between the phases, because the work for forming the critical size crystal nucleus is reduced, and the number of crystal nuclei is increased, thereby refining the grains.
- the low melting point elements such as magnesium and zinc are not used as the material for producing the strengthening phase, and the decomposition and conversion of the reinforcing phase of the material at high temperature are avoided, thereby significantly increasing the high temperature strength of the material.
- the fifth is one of 8 characteristic elements such as beryllium (Be), cobalt (Co), chromium (Cr), lithium (Li), molybdenum (Mo), niobium (Nb), nickel (Ni;), tungsten (W). , or a combination of any two of them, as a characteristic addition element of high-activity complex microalloying, can form a plurality of high-temperature strengthening phases in the melt, and at the same time have a function of a modifier to improve the room temperature and high-temperature strength of the alloy.
