Effect of preshrinkable expansion on dimensional accuracy of castings made of high-strength cast iron

Abstract
The effect of graphite inclusions on preshrinkable expansion in castings of high-strength cast iron is considered. A simulation model and software are proposed. It has been established that the preshrinkable expansion and as a consequence, the dimensional accuracy of castings of high-strength cast iron with spherical graphite are affected by the number and size of graphite inclusions. It is shown that in the fine-dispersed phase of graphite, the sample expansion is 1.74 times less than in the coarse-grained phase, and the dimensional accuracy of the sample is 2 classes higher.
