3.2. Mechanical properties The effect of cold rolling reduction on the Vickers hardness is shown in Fig. 5. The hardness values were found to increase with cold rolling. The cause of the change in hardness with cold rolling reduction may be attributed to the effect of the increased dis-
The results exhibited that under the same rolling conditions, the sheet after ordinary rolling exhibited obvious edge cracks while no crack was found at the edge of the sheet after width-limited rolling. The edge crack suppressing effect was attributed to the reduction of the tensile stress along rolling direction during WLR, promoting the Effect of Cold Rolling Process on Properties of Aluminum In the present study, the effect of the cold rolling process under the different reductions ratio (2.5, 5.0, and 7.5) were carried on AA 5456 Al-Mg alloy. During study, at the beginning and before starting the rolling process, the cast aluminum (AA5456) have been subjected to the heat treatments of homogenization at 450 °C for 18 hours and then annealing at a temperature 360
In this paper, a AlMgSi alloy for sheet materials was designed on the base of 6111 aluminum alloy, the alloy sheet was fabricated by the rolling process combination of hot and cold rolling, the effect of rolling process on the microstructure of alloy was studied. The results show that different 1st rolling pass reductions of 13%, 33% and 47%, alloy microstructure changes Effect of Rolling Temperature on Microstructure Evolution The impacts of rolling temperature on phase transformations and mechanical properties were investigated for AISI 316LN austenitic stainless steel subjected to rolling at cryogenic and room temperatures. The microstructure evolution and the mechanical properties were investigated by means of optical, scanning, and transmission electron microscopy, an X-ray diffractometer,
The results of this study indicate that the nanocrystalline grains grow up after rolling to a thickness reduction of 30%, 50%, and 70% at 700°C, the submicron crystalline grains were broken down and dispersed better in the matrix of the steel, rolled steel greatly increased its mechanical properties, as the deformation increased from 30% to 50 Effect of rolling reduction on microstructure, texture Effect of rolling reduction on microstructure, texture, mechanical properties and mechanical anisotropy of AZ31 magnesium alloys August 2014 Materials Science and Engineering A 612:208213
The effects of cold-rolling with different reduction ratios of 70%-90% on the microstructure and mechanical properties of Ti50Zr30Nb10Ta10 alloy were investigated. It was found that the -Ti phase in this alloy was stable under cold-rolling. With the increase in reduction ratio from 70% to 90%, the microstructure of the alloys evolved from deformed dendrite structure to Effects of Cr2O3 Content on Microstructure and Mechanical Feb 16, 2021 · Al2O3-Cr2O3 refractories are completely substitution solid solutions and can effectively resist slag erosion when used as an industrial furnace lining. In order to provide suitable chromium corundum refractory with excellent slag resistance and mechanical properties for smelting reduction ironmaking, Al2O3-Cr2O3 samples with different mass percentages (0,

Cold-rolling process is an important stage in Ti+P-IF steel manufacturing process, and cold rolling reduction is a main parameter. The research of recrystallization microstructure change and texture evolution of Ti+P-IF steel in cross cold rolling reductions has important meaning in study of high strong IF steel. In this paper, hot rolled Ti+P-IF steel in austenite was studied, cold rolling Influence of Cold Rolling Reduction on Microstructure and The present study investigated the effect of cold rolling reduction on microstructure and mechanical properties of a 204C2 CrMn austenitic stainless steel which contained 16%Cr, 2%Ni, 9%Mn and 0.083 %C). The 204C2 austenitic stainless steels were cold rolled at multifarious thickness reductions of 10%, 20%, 30%,40% and 50%, which were compared
