Corrosion Resistance of Directionally Solidified Casting Zinc-Aluminum Matrix

Optimization and utilization of semisolid casting process for semisolid welding of Al-6061 alloy

Semisolid processing is one of the modern routes in sound and near net shape parts production.  Preparation of semisolid slurry using a cooling slope is increasingly becoming popular, primarily because of its simplicity in design and ease of control of the process. In this research, the microstructures of Al6061 semisolid alloy cast via a miniature cooling slope were investigated. The propertie...

Effect of Aging Condition on Semisolid Cast 2024 Aluminum Alloy

2024 Aluminum alloy was squeezed cast by the Gas Induced Semi Solid (GISS) process. Effect of artificial aging on microstructure and mechanical properties of this alloy was studied in the present work. The solutionized specimens were aged hardened at temperatures of 175°C, 200°C, and 225°C under various time durations. The highest hardness of about 77.7 HRE was attained from specimen aged at th...

Research on Semisolid Microstructural Evolution of 2024 Aluminum Alloy Prepared by Powder Thixoforming

A novel method, powder thixoforming, for net-shape forming of the particle-reinforced Aluminum matrix composites in semi-solid state has been proposed based on powder metallurgy combining with thixoforming technology. The microstructural evolution and phase transformations have been investigated during partial remelting of the 2024 bulk alloy, prepared by cold pressing of atomized alloy powders...

Low temperature deformation behavior of an electromagnetically bulged 5052 aluminum alloy

The fundamental understanding of the deformation behavior of electromagnetically formed metallic components under extreme conditions is important. Here, the effect of low temperature on the deformation behavior of an electromagnetically-bulged 5052 aluminum alloy was investigated through uniaxial tension. We found that the Portevin-Le Chatelier Effect, designated by the serrated characteristic ...
