Microstructure Evolution in High Purity Aluminum Single Crystal Processed by Equal Channel Angular Pressing (ECAP)
Aluminum single crystal with 99.999% purity was deformed at room temperature by equal channel angular pressing (ECAP) up to 16 passes. Grain size and misorientation of processed samples were quantitatively characterized by TEM and EBSD. The results show that the refinement efficiency of high purity aluminum single crystal was poor in the initial stage. Extrusion by fewer ECAP passes (n ≤ 8) res...

V.A. Andreyachshenko, Faculty of Nanotechnology and Metallurgy, Karaganda state technical University, Karaganda, Kazakhstan A.B. Naizabekov, Mining and Metallurgy Faculty, Rudny Industrial Institute, Rudny, Kazakhstan In the present research, equal channel angular pressing (ECAP) was conducted. The defectness degree of the alloy for one pass and maximum strain was determined. Ultra fine grained...
متن کاملEqual 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 کاملModeling and production of high strength Al strips by equal channel multi angular pressing method
Equal channel multi angular pressing (ECMAP) process is the efficient method to enhance the productivity of ultra-fine grained (UFG) materials, by increasing process continuity and as a result decreasing process required time. Comparing repetitive ECAP method, in the same period, the number of passes can be done by ECMAP. In this article, ECMAP of AL strips in two typical annealed and as receiv...
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...
