As the pass number of pressing increases, the portion of high-angle grain boundaries increased.
随着道次的增加,大角度晶界的比例也跟着增加。
The transformation from low Angle grain boundaries to high Angle grain boundaries makes the number of high-angle grain boundaries increase continuously and finally the grains are refined markedly.
小角度晶界向较大角度晶界不断转变的结果使大角度晶界数量不断增加,最终导致晶粒显著细化。
The results indicate that the initial ferrite microstructure gradually developed into the equiaxed submicrometer grain microstructure with high angle boundaries with increasing the pass number.
结果表明,铁素体组织随变形道次的增加逐渐演变为等轴状大角度晶界的亚微晶组织;
