The modification of the Gladman's model may then be proposed by the comparison of different models of grain coarsening with assumption of uneven in convexo-concave interface along grains. The modified Gladman's expression is given as: R_o =πr/3f_v(3/-2/Z) that may fairly predict the actual grain size observed.
比较了已有的晶粒粗化模型，在晶界面为凸凹不平的曲面前提下，对Gladman模型做了修正，提出了如下的修正Gladman公式： R_0=πr/3f_v(3/2-2/Z)该公式能较好地预测晶粒的实际尺寸。
