发生物理现象的空间部分,称为物理场。根据这个定义塑性加工时的变形区称为塑性加工变形物理场。塑性变形过程中,由开始到终了,矢量参数(位移,变形,应力,速度等),标量参数(温度,密度,体积,硬度,屈服极限,强度极限,位错密度,金属组织的主体相与剩余相的尺寸等)、各种系数(变形系数,晶粒尺寸比值,延伸率,断面减缩率, The physical part of the physical phenomenon, known as the physical field. According to this definition of plastic processing deformation zone known as plastic processing deformation physics. During plastic deformation, the vector parameters (displacement, deformation, stress, velocity, etc.), scalar parameters (temperature, density, volume, hardness, yield strength, strength limit, dislocation density, The size of the remaining phases, etc.), various coefficients (deformation coefficient, grain size ratio, elongation, reduction of area,
