【 摘 要 】

The paper presents the developed mathematical model for calculating the crystallization parameters of engineering casting alloys processed by external physical impacts, allowing the critical size of the crystallizing nuclei to be predicted and the amount of nuclei for evaluating the effectiveness of the melt modifying treatment. To automate the calculations for the proposed model, the application software has been created using modern methods of visual software design on the basis of modular and object-oriented approaches. Using A356 aluminum alloy as an example, it was shown that the melt treatment by physical impacts helps to reduce the critical size of the crystallizing nuclei and increase their amount, with the greatest effect being achieved for alloys with a higher proportion of secondary materials in the charge. Prospects of using the calculation technique for the proposed mathematical model in real production conditions during development of technological processes for the production of foundry alloys and castings from them are indicated.
