采用粉末床增材制造（AM）技术对高合金CrMnNi TRIP钢进行了电子束熔化加工，研究了其疲劳性能。该材料在固溶状态下的平均晶粒尺寸为32 μ m，在溶液退火状态下的平均晶粒尺寸为106 μ m。应变幅值在0.25%范围内的全应变控制疲劳试验
A high alloy CrMnNi TRIP steel has been processed by electron beam melting, a powder-bed based additive manufacturing (AM) technology, to investigate its fatigue properties. The material was characterized by average grain sizes of 32 mu m in the as-built and 106 mu m in the solution annealed state. Total strain controlled fatigue tests with strain amplitudes in the range of 0.25%
