Influence of Alloy Gray Cast Iron Composition on the Mechanical Properties
The orthogonal experiment method was applied to research the effect of C,Cu,Cr,Sn content on the mechanical properties of alloy grey cast iron.The experiment was designed containing 4 factors and each factor has 3 levels.According to the common composition of alloy gray iron of diesel engine at home and abroad,the content were controlled as below: carbon in the range of 2.6%～3.3%,copper in the range of 0.4%～0.7%,chromium in the range of 0.35%～0.55%,tin in the range of 0.02%～0.10%.According to the experiment results,the effects of these four elements on the hardness and tensile strength in alloy gray cast iron were in the order of CSnCuCr.
