Effect of High-Temperature Thermomechanical Processing on the Heat Resistance of the Alloy KhN70 VMTYu (Vlyanie Vyskotemperaturnoi Termomekhanicheskoi Obrabotki Na Zharoprochnost Splava Kh70 VMTYu),
Abstract
One of the promising methods for hardening metals is high-temperature thermomechanical processing (HTMP); it involves a combination of hot plastic deformation and tempering. This paper gives some results of a study of the effects of various HTMP variants with the deformation of billets by drop-forging on the heat resistance of the alloy E1617 (KHn70VMTYu) with a nickel base. HTMP was performed using a crankshaft press with a maximum force of 2500 tons. Examination of many tests on variants reveals that the optimum HTMP variants for the alloy E1617 is forging at 1100-1050C with settling by 9-12% and cooling of pretempered billets in the air. The results indicate that it is desirable to use HTMP in forging turbine blades from the alloy E1617. (Author)
