| Abstract: | After long-term aging,the 14%Cr-5%Ni maraging steel is heat-treated,and itsstrength increases;the impact toughness is lowered,and the alloy becomes brittle.The re-sults show that the alloy embrittlment is related to the formation of the micro-enriched zonesof the alloy elements Ni,Cr etc.and harmful elements,such as P,at the original Austenitegrain boundary. |
