HIGH-TEMPERATURE FORMING TOOL

HIGH-TEMPERATURE FORMING TOOL

A high-temperature forming tool is formed at least partly of a molybdenum-based alloy having a fraction of molybdenum of ≥90 wt. %. The molybdenum-based alloy is in a pressed-and-sintered state and in the pressed-and-sintered state has a thermal shock resistance of at least 250 K. The thermal shock...

Zusammenfassung:A high-temperature forming tool is formed at least partly of a molybdenum-based alloy having a fraction of molybdenum of ≥90 wt. %. The molybdenum-based alloy is in a pressed-and-sintered state and in the pressed-and-sintered state has a thermal shock resistance of at least 250 K. The thermal shock resistance is defined as the quotient of ReH/(α·E), where ReH is the yield point at room temperature in MPa, a is the thermal expansion coefficient in 1/K and E is the elasticity modulus in MPa.
