Effect of Vegetable Based Lubricants on Equal Channel Angular Extrusion Pressure

Size effect in equal channel angular pressing (ECAP) process

The influence of the sample size (diameter while keeping the length constant) in equal channel angular pressing (ECAP) of pure aluminum is examined using finite element method (FEM) and experiment. Different sized aluminum rods were processed via ECAP and the effect of sample size on the strain homogeneity, process load, and the ratio of the friction to the total force were evaluated. The resul...

Plastic deformation of 7075 Aluminum Alloy using Integrated Extrusion-Equal Channel Angular Pressing

Grain refinement improves the mechanical properties and formability of metals and alloys. So far, several different grain refinement methods have been proposed and studied. Severe plastic deformation is one of the most promising and efficient methods. Therefore, in the present study the possibility of imposing a two-step severe plastic deformation (Extrusion and Equal channel angular pressing) ...

Consolidation of Fe-N Magnets Using Equal Channel Angular Extrusion

A new design for equal channel angular extrusion

A new die design has been proposed for processing of materials using Equal Channel Angular Extrusion (ECAE). The proposed design is an improvement over the existing ones and has an additional attribute to process materials at high temperatures (up to 500 oC). The design has been tested for different materials at different temperatures and it has shown the benefit of reducing the load requiremen...

Parameter Analysis and optimization of equal channel angular pressing extrusion for titanium alloy using Taguchi design of experiments method

In this paper the influence of different parameters on equal channel angular pressing (EADAP) of titanium alloy is investigated. In the first step the most important parameters are selected, and then a table of experiments is designed using Taguchi method. After designing the table of experiments, all of the experiments are simulated using Abacus software and the results are optimized using Tag...
