Abstract
The artificial aging behavior of Al-Si-Mg alloy naturally aged for 1 hour and 7 days at room temperature was analyzed using hardness, DSC and TEM. The Al-Si-Mg alloy naturally aged for 7 days at room temperature showed a decrease in maximum hardness during artificial aging at 160^oC compared to the..... More

Abstract
The effects of Mg content and cooling rate on the T5 treatment of Al-Si-Mg alloys have been investigated using Avrami kinetics and transmission electron microscopy. The alloys were super-heated at 800 ^oC for 1 hr followed by degassing treatment at 720 ^oC for 15 min, and poured into a metallic..... More
