Microstructure and Induced Defects of 6061 Al Alloy after Short Times Cyclic Semi-Solid Heat Treatment

Effect of Deformation-Induced Defects on the Microstructure and Pitting Corrosion Behavior of Al-Ag Alloy

In this study, a wide range of combined ageing treatments and cold work deformations in the Al 4.2 wt% Ag alloy matrix were proposed, aiming to investigate the effect of defects such as precipitates (Ag2Al plates) and dislocations on the mechanical and electrochemical behavior of Al–4.2 wt% Ag alloys. Further reductions of thickness from 10 to 60%, decreases the mean size of Ag2...

The effects of maintaining temperature in annealing heat treatment for an FSWed 6061-T6 Al alloy.

The technological development of all kinds of lightweight transportation devices including vehicles, aircraft, ships, etc. has progressed markedly with the demand for energy saving and environmental protection. Aluminum alloy is in the spotlight as it is a suitable environmentally friendly material. However, deformation is a major problem during the welding process because aluminum alloy has a ...

EFFECTS OF Al-5TI-1B MASTER ALLOY AND HEAT TREATMENT ON THE MICROSTRUCTURE AND DRY SLIDING WEAR BEHAVIOR OF AN Al-12Zn-3Mg-2.5Cu ALLOY

In this study the effect of Al–5Ti–1B grain refiner on the structural characteristics and wear properties of Al–12Zn–3Mg–2.5Cu alloy was investigated. The optimum amount for Ti containing grain refiners was selected as 2 wt.%. T6 heat treatment, (i.e. heating at 460 °C for 1 h before water quenching to room temperature and then aging at 120 °C for 24 h) was applied for all specimens before wear...

Al-7Si-Mg Semi-Solid Castings – Microstructure and Mechanical Properties

Optimization of Microstructure and Mechanical Properties of Al-A360 Produced by Semi-Solid Casting

Semi-Solid Casting (SSM) is a new process that could produce globular structures with mechanical properties. The cooling slope method (CLM) is a one of this process that was employed to produce the A360 feedstock. In this method, The dendritic primary phase in the conventionally cast A356 alloy has transformed into a non-dendritic one. In this paper, The molten alloy with the temperature (PT) o...
