摘　　要：钼棒材的均匀性对后续产品质量有着重要影响。将一根覫90 mm纯钼棒沿纵向和横向均匀切割,获得边部和芯部各30个检测样本,通过对试样的晶粒数、硬度、密度的检测和C、O、Fe、K含量测试,根据检测数据的分布,评价了试样的均匀性。The uniformity of the molybdenum bar has an important impact on the subsequent products＂ quality. 30 samples are obtained by uniformly cutting a 090 mm pure molybdenum bar longitudinally and transversely. The uniformity of the bar is examined and assessed by testing numerical distribution of the grain number, hardness, density and the contents of C, O, Fe, K of the samples.
