Homogenizationtreatment before the extrusion coarsened the grain size and reduced the tensile strength and yield strength.
挤压前均匀化热处理使挤压态合金的晶粒尺寸粗化，拉伸强度和屈服强度降低。
2
Therefore, the combined homogenizationtreatment with and without an electric field is an effective method of homogenizationtreatment.
因此，电场及非电场的联合处理方法是一个有效的均匀化处理制度。
3
The effects of different cooling manners on the structure and properties of aluminum-lithium alloy 1420 ingot as after homogenizationtreatment were investigated.
