THE EFFECT OF SEVERE PLASTIC DEFORMATION ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF AS-CAST AZ31

The evolution of microstructure and mechanical properties of a magnesium cast alloy (AZ31) processed by equal channel angular pressing (ECAP) at two different temperatures were investigated. The as-cast alloy with an average grain size of 360  was significantly refined to about 5  after four ECAP passes at 543 K. Grain refinement was achieved through dynamic recrystallization (DRX) du...

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...

Investigation of microstructure and mechanical properties of low carbon steel sheets after severe plastic deformation in corrugation dies

Recently, bulk nano-structured materials produced by severe plastic deformation (SPD) have attracted scientists attention.  Materials produced by SPD are of great importance because of (1) non-porous structure, (2) great mechanical properties such as high strength and toughness and (3) proper dimension for mechanical and physical testing.  Several methods have been introduced for imposing the s...

Improving 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...
