Влияние всестороннего газового давления на горячеломкость отливок

The factors causing the olives tendency to hot cracking of aluminum-based alloys, the mechanism of the influence of hydrostatic pressure on the gas liquid melt. Produced simulation of filling and solidification to determine the hot cracking software package ProCAST c using samples Trubitsina. Identified inaccuracies caused by the fact that the chill is taken into account by the program as statically indeterminate solid object. Produced by designing a full set of tooling for testing aluminum-based alloys to hot brittleness and modeling processes pouring, solidification and hot cracking in the new chill. When modeling in the chill-designed to install additional element defined as statically indeterminate for binding calculation of the stresses in the crystallization of the sample.
