Effect of Titanium on Microstructure of Al2014 Alloy Prepared by SIMA Process

Abstract:

Forming in semi-solid state to achieve globular microstructure has an effective influence on mechanical properties of aluminum alloys. In this research, the Al2014 alloy was prepared by a semi-solid strain-induced melt activated (SIMA) process. In order to analyze the effect of titanium content on the macrostructure of Al2014, the optimum amount of titanium according to its efficiency on reducing the grain size was obtained. Then, specimens with optimum titanium content were prepared by the SIMA process. Cold working was applied on specimens by an upsetting technique. Cold worked specimens were heat treated at 595, 605, 615, 625 and 635°C and were kept at these temperatures for 30 min to achieve a globular structure. Observations through optical and scanning electron microscopy (SEM) revealed that by increasing the temperature, an increase in sphericity and grain size occurs. According to the results, optimum condition in order to achieve a fine and globular microstructure is keeping specimens at 625°C for 30 min.
