| Abstract: | There times of melting tests were carried out on 60CrV round steel in a vacuum induction furnace by addition of Lace alloy.Effects of Lace alloy on the structure and mechanical properties of 60CrV steel such as morphology of inclusions,pearlite lamellar spacing,R00.2,Rm,shock resistance and hardness were investigated.The results show that rare earth can change the morphology of inclusions in the steel,decrease the pearlite lamellar spacing and improve the toughness and shock resistance. |
