摘要: AbstractThe present study focuses on the effects of temperature hot isostatic pressing (HIP) procedure Inconel 718 superalloy. HIP temperatures used were 1150, 1175, 1180 and 1205°C. pressure was maintained at 1000 bar (98·6 MPa) soaking time 2 h. Both room high tensile bending tests to evaluate Porosity microstructural examination performed. The results showed that optimum process for superalloy is 1180°C. Processing this can significantly reduce porosity improve microstructure segregation Under these conditions, an 18·28% increase in strength temperature, a 7·38% 540°C, 3·84% 650°C. elongation increased by 55·6% 109·71% 19·91% Finally, three-point th...
