Effect of Remain Casting Microstructure on Properties of Cast Steel
By means of comparison and analysis on macrofracture,microfracture,microstructure,the effect of remaining casting microstructure on properties of cast steel was studied.The results show that for the samples with remaining casting microstructure after normalizing,its tensile strength and elongation can be up to standard,and its fracture contraction rate reduces a little,but its impact work becomes lower than the samples with normal microstructure.
