The sequence of intermetallic formation and solidification pathway of an Al-13Mg-7Si-2Cu in-situ composite

The phase transformation sequence and solidification behaviour of an Al-13Mg-7Si-2Cu in-situ composite was examined using a combination of computer-aided cooling curve thermal analysis and interrupted quenching techniques. Five different phases were identified by analysing the derivative cooling cur...
