Severe Plastic Deformation of Metals
This paper provides an introduction in the field of severe plastic deformation (SPD). First of all the main methods to produce SPD materials are discussed. In the following section, the mechanisms leading to the formation of fine grains are reviewed and the influence of changes in strain path is highlighted. During post-SPD thermal annealing, some typical microstructural changes take place. The...
متن کاملThe methods of sever plastic’s deformation in order to fine-graining matter’s structure for improvement of mechanical properties in metals
Increasing material’s strength has been a significant matter since the beginning of engineering to up to now. It has always been paid attention by engineers. A variety of methods has been presented for increasing strength, stability, working range and material working life by development of engineering sciences and more identification on material properties and the material behavior, which are ...
متن کاملDrawing CCCT Diagrams and Investigation of Deformation Effects on Martensite and Bainite Trabsformations in NiCrMoV Steel
In this study, two CCCT diagrams are drawn to be compared with a CCT diagram. The CCCT diagrams represent continuous cooling transformations in stress assisted state. The increased Md and Bd temperatures of CCCT diagrams were also compared with those of the CCT diagrams and the cause was investigated from both thermodynamic and metallurgical viewpoints. Thermodynamic examinations revealed that ...
متن کاملStrengthening of Metals through Severe Plastic Deformation
The processing of bulk metals through the application of severe plastic deformation (SPD) provides an opportunity for achieving excellent grain refinement to the submicrometer or even the nanometer range. These SPD procedures produce materials exhibiting improved mechanical properties including very high strength. This report describes recent results demonstrating the strengthening of conventio...
