Abstract

Abstract

The high temperature mechanical properties of GCr15 bloom, such as yield strength, tensile strength, hot elasticity and hot ductility, have been detected by thermal-tensile tests using a Gleeble-1500D system respectively.The thermal-tensile tests show that the yield strength, tensile strength, elasticity modulus and plasticity modulus of steel decrease with the increase of test temperature and the bloom has easily plasticity deformation affected by external force in high austenite temperature, then has crack defect.The second embrittlement zone of GCr15 bloom occurred in the temperature range 725℃to 800℃.
- bearing steel,
- high temperature strength,
- percent reduction of area,
- elasticity modulus,
- plasticity modulus
