at 200 kV. 3 Results and discussion 3.1 Influence of age forming on microstructure The four-stage precipitation sequence of the ageing of Al-Cu-Mg alloys is as follows: SSS→GPB zone→S′′→S′→S
/Mechanical/Thermo mechanical surface engineering treatments will produce extensive rearrangement of atoms in metals and alloys and corresponding marked variations in Physical, Chemical and Mechanical properties. Among the more important of these treatments are heat treatment processes such as hardening by Quenching, Induction hardening and Case Carburizing which rely on phase transformations to produce......
