Analysis of Dependence of the Properties of Alloy V95 on the Pressure Applied to Crystallizing Metal

  • Published:
Metal Science and Heat Treatment Aims and scope

Results of a study aimed at formation of a single-phase fine-grained structure in pistons from aluminum alloy V95 in the process of their fabrication, which involves isostatic pressing of liquid metal before the start of crystallization, application of pressure to the crystallizing metal, and holding under pressure in the process of cooling to the shop temperature, are presented. The ultimate strength and the structure of alloy V95 after casting with imposition of pressure are determined. An example of application of the method suggested for fabricating cast billets ∅ 82 × 70 mm in size with a uniform dense structure without gas shrinkage defects, volume and dendritic segregation is considered.
