| 11 | Effect of Lanthanum on Mechanical Properties of ZL702 Alloy at Room and High Temperature Condition显示文摘Effects of lanthanum on microstructure and mechanical properties of ZL702 alloy at room and high temperature conditions are studied. The experiment shows that high temperature intermetallics reticularly distributing at grain boundary are formed with La and Al, Si, Fe etc. elements of alloy, which enhances the thermal stability of the alloy. With appropriate content of La (0.10%~ 0.15%), the mechanical properties of the alloy, such as strength, at room temperature and high temperature can be improved. | LI Pei jie 1,2 , ZENG Da ben 1, JIA Jun 2, LI Qing chun 2( 1.
