| Abstract: | With grain refining, and morphology and distribution of inclusions improving by adding
micro\|alloying element \| Nb, V, Ti, RE and Ca, the impact toughness, elongation and reduction of
area of new C 0.10.5\|Cr 1.05.0\|Mo 0.32.0\|Ni 1.02.0 steel for cast hot\|forging die increased by
over 1 time, and the fracture toughness and thermal fatigue resistance of steel improved
obviously. |
