The Mechanics Properties of the Rene95Samples Produced by the Laser Rapid Forming Process

Abstract:

The samples of Rene95high-temperature alloy for mechanics property mea surement have been produced by the Laser Rapid Forming process.Through optimizin g the processing parameters the geom etric properties of the dense sample s were controlled accurately.And the heat treatment process plays a re markable role in improving the mechanics properties of the Rene95sample s.The testing results show that the tensile strength of the samples h as approached that of the C grade criterion of the powder metallurgy and th e ductility even exceed that of the A grade criterion.The mean micro hardness is HV 496.3.
