Microstructure and Properties of Ti6Al4V Alloy Prepared by Hot Isostatic Pressing

Abstract:

Pre-alloyed Ti6Al4V powder produced by plasma rotating electrode process (PREP) was consolidated by hot isostatic pressing (HIP) under the parameters of 930°C/100MPa/3h. The microstructure is analyzed using scanning electron microscopy (SEM). The tensile property is measured at room temperature, the fracture surface morphology of the tensile specimens was investigated using SEM as well. The results show that the dense body has homogeneous microstructure and fine grain size. The average values of ultimate tensile strength (UTS), yield strength (YS) and elongation (EL) are 1119 MPa, 1043 MPa and 18% respectively. The fracture of specimen presents ductile fracture.
