Microstructure of a low alloyed Cu-Cr-Zr alloy after ECAP-Conform
نویسندگان
چکیده
The microstructure of a Cu-0.1%Cr-0.1%Zr alloy after annealing or aging and equal channel angular pressing with conform (ECAP-C) process was investigated. ECAP-C led to formation strain induced low-angle boundaries (LAB) which transformed in high-angle (HAB) during deformation. Deformation microbands developed 1 pass, leading new ultrafine grain the upon further processing. Average size gradually decreased while dislocation density increased. After 8 passes average achieved μm. Maximum LAB occurred 4 ECAP then HAB increased ECAP-C. Relationships between density, size, crystallite were discussed.

Grain Refinement Kinetics in a Low Alloyed Cu–Cr–Zr Alloy Subjected to Large Strain Deformation
This paper investigates the microstructural evolution and grain refinement kinetics of a solution-treated Cu-0.1Cr-0.06Zr alloy during equal channel angular pressing (ECAP) at a temperature of 673 K via route BC. The microstructural change during plastic deformation was accompanied by the formation of the microband and an increase in the misorientations of strain-induced subboundaries. We argue...
متن کاملEffect of ECAP Deformation Route on the Degree of Anisotropy of Microstructure of Extremely Low CN Fe-20mass%Cr Alloy
The effect of the deformation route on the microstructural evolution of low CN Fe-20%Cr alloy by ECAP has been investigated, with a focus on the anisotropy of the microstructure. This alloy was pressed at 423 K from one, two and four passes via routes A, Bc and C, and the microstructure was observed three dimensionally. As has been acknowledged, overall grain fragmentation proceeded most effect...

This study focused on the effect of electro slag remelting process (ESR) on microstructure and composition of an as-cast alloy of Cu-Cr-Zr. These observations revealed that applying ESR process results in a more uniform distribution of alloying elements, however a slight aggregation of large precipitates and inclusions existed in as-cast ingot was found. Additionally, impurities like P, S and M...

The microstructure, hardness evolution, and thermal stability of mechanically alloyed (MA-ed) nanocrystalline Cu–10 wt %Nb solid solution during heat treatment were examined using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM) observations, and microhardness measurement. It is found that the pronounced precipitati...
متن کاملMicrostructure of Ultrafine- Grained Metals after Ecap
This paper was aimed at verification of functionality of the ECAP technology at extrusion of the copper, alluminium alloys and steel. Experiments were made on equipment, which is demonstrated in the Fig 1. Deformation forces were measured during extrusion, resistance to deformation was calculated and deformation speed was determined approximately. Analysis of structure was made with use of ligh...
