    摘要:

    采用優(yōu)化的激光快速成形工藝參數(shù)，獲得了成形精度得到控制、組織致密的Rene95高溫合金力學(xué)性能試樣。為了提高成形試樣的力學(xué)性能，對試樣進(jìn)行了固溶 時效熱處理。力學(xué)性能測試結(jié)果表明，成形試樣的強(qiáng)度指標(biāo)已經(jīng)接近粉末冶金C級標(biāo)準(zhǔn)，塑性指標(biāo)超過粉末冶金A級標(biāo)準(zhǔn)。試樣平均硬度達(dá)到HV496．3。

    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.
