Abstract

The forming process of aerospace parts by special isothermal hydraulic presses of 6,3 and 16 MN with additional technical equipment is considered. Technological capabilities of their effective use for manufacturing parts of various typical sizes from Titanium-based, Nickel – based and other alloys in air environment using ZhS6U cast alloy dies are shown. Influence of low-speed forming in various temperature gradients between workpiece and die on power parameters of forging, forming process of workpieces and their structure changes are studied. The article presents the possibility of using the heat exchange between workpiece and die to improve deformation process. The work is executed within implementation of the complex scientific direction 10.2. «Isothermal deformation on air of heterophased difficult-to-form superalloys of new generation» («The strategic directions of development of materials and technologies of their processing for the period till 2030»)
