چکیده
A356 aluminium alloy is subjected to heat treatment and high-pressure torsion (HPT) processing investigate the impact of combined treatments on alloy’s microstructure refinement, corrosion resistance hardness. The process was performed at room temperature for 0.75 5 turns. Subjecting Al a subsequent HPT produced more refined microstructure, which has effect enhancing hardness under fragmentation homogenous redistribution intermetallic compounds Si particles. results show that there marked increase in when imposing strain from 61 HV 198 alloy, been HPTed heat-treated five polarisation curves considerable improvement rate 0.043 mm·year?1 sample 0.003 after turns HPT. In this work, refinement resulted both mechanical strength 356 comparison untreated alloy.

The Influence of Heat Treatment and High Energy Ball Milling on the Density, Hardness, and Wear Behavior of Al 7150 Alloy via Hot Uniaxial Compaction
The effect of the milling time & ageing on the hardness, density, and wear characteristics of Al 7150 alloy specimens made via powder metallurgy has been studied. The different constituents of Al 7150 alloy were processed in a planetary ball milling set up with a BPR of 10:1 for 5 hours, 10 hours, and 20 hours. At 400 °C, the milled powders were subsequently hot compacted in a punch die setup. ...
متن کاملInvestigation of the T4 and T6 Heat Treatment Cycles of Semi-Solid Processed Aluminium Alloy A356
The heat treatment cycles that are currently applied to semi-solid processed components are mostly those that are in use for dendritic casting alloys. These heat treatments are not necessarily the optimum treatments. It is shown that a decrease of the solution treatment time at 540 o C from 6 hours to 1 hour does not alter the T4 or T6 tensile properties of the SSM processed A356 alloy. Slightl...
