• 特殊

  Meanwhile,nearly half of∑9 grain boundaries and a small number of random HABs possess good intergranular corrosion resistance,which indicates that the specialness of grain boundary is not only related to the misorientation of the neighboring grains but also related to the grain boundary plane location.

  约有50%的∑9晶界和少数一般大角度晶界在腐蚀抗力上表现出特殊性,分析表明晶界的这种特殊性不仅和构成该晶界两侧晶粒的取向差有关还和晶界所处的晶面位置密切相关。
