annealed steel meaning in English

退火钢

With plating time going on , the nano - polycrystal gathering grows in two dimensions , and the new nano - polycrystal layer appears simultaneously on the formerly formed nano - polycrystal surface . because the boundary and defect densities in quenched and tempered 45 steel is higher than those in annealed steel , the nano - polycrystal gatherings formed at its surface at the beginning of electro - deposition are more concentrated , and then their size is smaller . the microstructure of the ni - p alloy coating has closed relation with its phosphorus content with the increase of phosphorus content , the microstructure of coating turns from nano - crystalline to the amorphous
随着施镀时间的延长，纳米晶聚晶体在横向二维生长的同时，在纳米晶聚晶体的表面上也进行着三维方向的新的一层聚晶体的生长；在调质态45钢表面，由于其具有比较高的晶界和缺陷密度，因此在沉积初期，纳米晶聚晶体的成核密度也较大，从而在二维方向聚晶体的尺度较小，镀层沉积初期表现为致密细小的鳞片状组织。
