Analysis of working conditions of cast materials operating at 950-1000 °C and requirements for stamping in isothermal conditions

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.
