Reasons for changes in the organizational structure of the straight wire drawing machine

Dec 31, 2020

The reason for the changes in the structure and performance of the straight wire drawing machine may be due to the uneven deformation of each crystal grain and the same crystal grain during plastic deformation of the polycrystal, and the elastic recovery of each crystal grain after the external force is removed. Not the same, so there is stress.

Plastic deformation increases the mobility of atoms and causes the corrosion resistance of metals to decrease. Plastic deformation of metal parts includes volume deformation, warping deformation and aging deformation in terms of macroscopic morphological characteristics. The volume deformation of the straight wire drawing machine refers to the phenomenon that the mass heat capacity changes due to the transformation of the metallographic structure of the metal parts during the heating and cooling process, resulting in the volume expansion and contraction of the parts.
