低合金耐热钢主要通过钢的合金化和适当的热处理，达到强化固溶体、强化晶界及沉淀强化的目的，从而提高钢的高温性能。２．２５Ｃｒ－１Ｍｏ钢中弥散析出的碳化物对位错的移动具有阻碍作用，尤其是碳化物以一定的位向关系从基体中析出时，这种作用更加明显，可以有效地提...
Low-alloy heat-resistant steel is mainly alloyed by steel and proper heat treatment to achieve the purpose of strengthening solid solution, strengthening grain boundaries and precipitation strengthening so as to improve high-temperature performance of steel. 2.25Cr-1Mo steel dispersed in the carbide carbide dislocation on the movement of the obstruction has an obstacle, especially when the carbide to a certain bit from the matrix precipitation, this effect is more obvious, can be effectively ...
