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 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...
متن کاملImproving Mechanical Properties, Especially Increasing Tubes’ Strength by Micro structuring Metals Using Severe Plastic Deformation Method
Increasing material’s strength is of particular importance. Improving material’s mechanical properties such as strength could reduce the size and weight of the structure. The size and weight of the structure are among the effective parameters in design. Since the past a variety of methods have been developed to increase the strength of metals that are capable of increasing metals’ strength to a...
متن کاملNumerical Analysis of Severe Plastic Deformation by High Pressure Torsion
High-pressure torsion (HPT) is a metal processing method in which the sample is subjected to a very high plastic shear deformation. This process can produce exceptional levels of grain refinement, and provides a corresponding improvement in mechanical properties. To investigate the stress and strain distribution due to HPT process finite element simulation were conducted to investigate effectiv...
