MICROSTRUCTURE AND MECHANICAL PROPERTIES OF THE ULTRAFINE-GRAINED COPPER TUBE PRODUCED BY SEVERE PLASTIC DEFORMATION
In this paper, cyclic flaring and sinking (CFS) as a new severe plastic deformation (SPD) method was employed to produce the ultrafine grain (UFG) copper tubes. The extra friction has eliminated in the CFS method that provided the possibility for production of longer UFG tubes compared to the other SPD methods. This process was done periodically to apply more strain and consequently finer grain...
متن کاملNew geometry for TCP: severe plastic deformation of tubes
Since tubes are widely used for different industrial applications, processing of tubes by the Severe Plastic Deformation (SPD) method has been the target of different attempts. Among these attempts, development of SPD processes for tubes based on Equal Channel Angular Pressing (ECAP) has been more successful. As an illustration, Tube Channel Pressing (TCP) has been presented as an attractive SP...
متن کاملNano- and Micro-mechanical Properties of Ultrafine-Grained Materials Processed by Severe Plastic Deformation Techniques
The processing of metals through the application of severe plastic deformation (SPD) techniques provides the potential for achieving exceptional grain refinement leading to ultrafine-grained (UFG) materials in bulk solids. These materials generally exhibit high strength but very limited ductility at room temperature (RT) leading to the so-called paradox of strength and ductility. The recent dev...
متن کاملThe Ultrafine-Grained Titanium and Biomedical Titanium Alloys Processed by Severe Plastic Deformation (SPD)
the function of our tissues and organs. Among the biomedical materials, titanium alloys have received attractions for dental and orthopedic implants due to their high strength, great corrosion resistance and biocompatibility, and low density [1,2]. Recently, a series of new β titanium alloys have been developed with low elastic modulus, containing non-toxic alloying elements such as Nb, Ta, Zr ...
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...
