    摘要:

    采用优化的激光快速成形工艺参数,获得了成形精度得到控制、组织致密的Rene95高温合金力学性能试样。为了提高成形试样的力学性能,对试样进行了固溶 时效热处理。力学性能测试结果表明,成形试样的强度指标已经接近粉末冶金C级标准,塑性指标超过粉末冶金A级标准。试样平均硬度达到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.
