Strengthening of Cr?Mn?Mo steel by cold-plastic deformation
Metal Science and Heat Treatment, 19661. The hardening of 28Kh10G8M4 steel during cold-plastic deformation is due to the formation of martensite resulting from deformation and to cold working of the austenite. 2. Hot rolling at 1100°C, with subsequent cold deformation with 30% deformation and tempering at 500°C for 1 h, results in the following characteristics: σb=190–215 kg/

Cold pressure welding of severely plastically deformed aluminium by divergent extrusion
Materials Science and Engineering: A, 2010The present investigation is concerned with cold pressure welding (CPW) of severely plastically deformed (SPD) aluminium. As a starting point, commercially purity aluminium is subjected to single pass equal channel angular pressing (ECAP) and subsequently joined by divergent extrusion (DIE).

Calculation of Joint Plastic Deformation to Form Metal Compound in Cold Condition
Solid State Phenomena, 2017The 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

Dislocation structure of cementite in granular pearlite after cold plastic deformation
The Physics of Metals and Metallography, 2013Cementite microstructure of the U8 steel with a granular pearlite structure has been investigated by the method of electron microscopy. It has been established that, at the early stages of deformation, carbide particles are deformed through the movement of stacking faults, which are characterized by an α[010] partial shift in the (001) planes of ...

Properties of stainless steels of the transition class after cold plastic deformation
Metal Science and Heat Treatment, 19741. For stainless steels of the transition class the highest strength properties are obtained by multiple cold plastic deformation and subsequent aging. 2. For unaged stainless steels of the austenitic — martensitic class there is no direct relationship between the amount of martensite and the strength characteristics.

Thermodynamic Behavior of Solid Polymers in Plastic Deformation and Cold Drawing
1992The mechanical work spent on the irreversible deformation of solids is always at least partly dissipated. Therefore, independent of the sign of the heat effect resulting from the elastic deformation, plastic deformation is always accompanied by an exothermic effect.
