چکیده

The present work reflects the effects of trace addition copper (up to 1 wt.%) and zinc (0.5 on microstructure hardness property heat treated A356 (Al-7Si) alloy. Small amount was introduced into in both atomic form (alloy) powder (composite) its age hardening behaviour were investigated. To enhance wettability during composite fabrication solid solution strengthening alloys, a small quantity magnesium (1 added. main objective this study is introduce lower melting point reinforcement matrix alloy by coating particles then reinforcing it matrix. All stir cast specimens subjected T6 treatment solutionizing at 520 °C for 2 h followed 60 water quench aging 100 200 determine peak value. Microstructure analysis showed that minimum wt.% required Al Cu intermetallic phase solidification resulting finer grain structure with improvement. Under as-cast conditions, maximum 85 VHN obtained reinforced composite. aged 116% improvement

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...

Effect of Solution Treatment Temperature on Microstructure and Mechanical Properties of A356 Alloy

Over the years, aluminum content in a vehicle part is increasing due to the needs to reduce weight as well as increase fuel efficiency. Most of the cast product in a vehicle part is mostly cast from A356 alloy. It is used because A356 alloy posses’excellent characteristics over other type of alloy such as cast ability, high weight-to-strength ratio, good corrosion resistance and good weld-abili...

Effect of the asymmetrical rolling process on the micro hardness and microstructure of brass wire

Current experimental investigation deals with the effects of asymmetrical rolling parameters on the inhomogeneity, microstructure, mechanical, and geometrical properties of rolled brass wire. Toward this end, a roll machine with three different roll radii ratios was set up. The asymmetrical conditions are arranged using three different sets of rolls with different diameters that result into dif...
