| Abstract: | The relationship between several structure factors and tensile strength of gray irons at higher carbon equivalents was studied by comprehensive and regressive analysis. Desired, variations in solidification structure were obtained by varying carbon equivalent and adding a little amount of alloy elements into the heats. The results indicate that austenitic dendrite quantity, graphite quantity, graphite size and micro-hardness of matrix are principal factors affecting strength of high carbon equivalent gray iron. |
