Effect of heat treatment on gravity die-cast Sc-A356 aluminium alloy

Investigation 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...

Regenerative Heat Treatment of Low Alloy Cast Steel

EFFECTS OF HOT ISOSTATIC PRESSING ON THE TENSILE PROPERTIES OF A356 CAST ALLOY

The influences of age hardening and HIP (Hot Isostatic Pressing) on the mechanical properties of A356 (Al 7Si 0.6 Mg) casting alloys were studied. Cast bars were homogenized, heated and maintained at a temperature of 540°C for a duration of 2 hours, followed by rapid cooling in a polymeric solution. The castings were age hardened at 180°C for a duration of 4 hours before being subjected to HIP ...

Effect of quartz-silicon dioxide particulate on tensile properties of aluminium alloy cast composites

This paper describes an experimental investigation of the tensile properties of quartz-silicon dioxide particulate reinforced LM6 aluminium alloy composite. In this experimental, quartzsilicon dioxide particulate reinforced LM6 composite were fabricated by carbon dioxide sand moulding process with variation of the particulate content on percentage of weight. Tensile tests were conducted to dete...

The Effects of Mould Materials on Microstructure and Mechanical Properties of Cast A356 Alloy

Abstract In this study, the effects of mould materials on microstructure and mechanical properties of cast A356 Al alloy were investigated. The alloy was poured into three different moulds. Then the samples were homogenised and applied T6 heat treatment. The optical, Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) studies were made. Secondary dendrite arm spacing (SD...
