摘要：
A comprehensive analysis of the shrinkage process during the crystallization of aluminum alloy castings was carried out. An assessment was made of the general nature of changes in filtration and shrinkage rates, as well as the width of the mushy zone, depending on the rate of crystallization of the melts. An analytical expression was proposed for determination of the critical value crystallization rate of the alloy from the standpoint of the probability of hot tearing in castings. The method of influence on crystallizing melts by vibration with the aim of reducing hot tearing is considered and experimental data confirming the effectiveness of this approach are given.
