Equal Channel Angular Pressing to Produce Ultrafine Pure Copper with Excellent Electrical and Mechanical Properties
In this article, commercially pure copper samples were severely deformed by equal channel angular pressing (ECAP) up to eight passes at room temperature. The effects of severe plastic deformation on the microstructure, mechanical properties, and electrical conductivity of the copper were investigated. The microstructure evolution was followed by optical microscope and field emission scanning el...
متن کاملDevelopment Microstructure and Mechanical Properties of Commercially Pure Titanium Processed by Equal Channel Angular Pressing and Cold Drawing
Equal channel angular pressing has been used to refine the grain size of commercially pure titanium (grade 2) as well as other metals and alloys. Titanium grade 2 is usually processed at about 350 °C because it lacks sufficient ductility at lower temperatures. The warm processing temperature limits the capability of the equal channel angular pressing technique in improving the strength of titan...

متن کاملBulk Nanostructured Refractory Metals with Enhanced Mechanical Properties Produced by Equal Channel Angular Pressing
The main aim of the current project has been to produce a batch of bulk billets with ultrafine-grained (UFG) microstructure and enhanced strength made of two refractory metals such as tungsten and tantalum. To process bulk W billets with UFG structure having a long-length size more than 100 mm we have developed and successfully used a new approach based on a combination of equal angular pressin...
متن کاملEFFECT OF POST-DEFORMATION ANNEALING TREATMENT ON INTERFACE PROPERTIES AND SHEAR BOND STRENGTH OF Al-Cu BIMETALLIC RODS PRODUCED BY EQUAL CHANNEL ANGULAR PRESSING
Effects of annealing treatment after equal channel angular pressing (ECAP) on the interface properties and shear bond strength of Al/Cu bimetallic rods were investigated. For the as-deformed samples, the one with two passes of ECAP indicated higher shear bond strength. Formation of a layer of intermetallic compounds after annealing treatment is confirmed. In general, by increasing annealing tem...
