Hot rolled stainless steel bars that are annealed and cold worked to produce a higher surface quality and higher strength.
经过退火及冷加工的热轧不锈钢棒材,其表面质量更高,强度也更高。
After the hot-worked surface has been cleaned and oxides removed, the metal can be cold worked to give the final dimensions and properties.
在对经过热加工的金属表面进行清洁和除去氧化 物后,可对金属进行冷加工得到最后的尺寸和性能。
In order to strengthen anti fatigue of cold worked hole, it is necessary to control the magnitude and distribution of the surface residual stress and strain.
为了使冷挤压孔真正起到抗疲劳增寿效果,有效控制孔表面残余应力大小及其分布是至关重要的。
The results show that the stress and strain distribution around the cold worked hole are similar between the model and real object.
结果表明:带衬套挤压和不带衬套冷挤压时孔边载荷的分布,模型材料与原型实际挤压结果相似;
