图1 316不锈钢的(Cr, Si, Mo)-(Ni, Mn)-Fe伪三元成分图，单位为原子个数(总和为16)。红色虚线围成的区域代表316不锈钢国标成分区间，蓝色实线ABFE围成的区域为316不锈钢根据团簇式优化后的国标成分区间，红色三角形符号代表基于团簇式设计的五个合金成分点

Fig.1 (Cr, Si, Mo)-(Ni, Mn)-Fe pseudo-ternary composition diagram of 316 stainless steel with the unit of number of atoms (total number per cluster formula being 16). The area enclosed by the red dotted lines represents the composition zone of 316 stainless steel in GB standards, while that by the blue solid lines labelled as ABFE is the optimized composition zone according to the cluster formulas, and the red triangles represent the designed compositions based on the cluster formulas
