Analysis of Working Conditions of Cast Materials Operating at 950–1000 °C and Requirements for Stamping in Isothermal Conditions

Abstract

The article is devoted to stamp cast parts which are operating in complex thermo-mechanical conditions at high temperatures. Main causes of their failure are stamp gravure wear, gravure elements collapse and thermal fatigue cracks. Research of the formation mechanism of these defects in a solid cast stamp will enable to manufacture high heat resistance alloys and to extend the stamp life during isothermal deformation.
