Calculation of Joint Plastic Deformation to Form Metal Compound in Cold Condition

Abstract:

The author of the paper proposed a model of joint plastic deformation of two metals in cold state. That model is based on a well-known "oxide" hypothesis. It was demonstrated experimentally that steel/ brass close contact occurs as early as at the degree of deformation 0.15–0.20, but this level of deformation is insufficient to form a compound. A close contact of metals is a necessary but insufficient condition for compounding metals in cold state. The sufficient condition for two metals compounding is the degree of deformation more than 0.50. At this deformation level juvenile metal surfaces begin entering into contact by forming adhesion bridges.
