Advanced Physical Metallurgy of Alloys and Thin Films of Semiconductor

Starting with studies of equilibrium phase diagrams, thermal ageing and external stress induced phase transformations in Zn-Al based alloys were investigated. Complex non-equilibrium phase transformations in various processes were also studied. Intrinsic phase relationships between equilibrium and non-equilibrium of alloys under thermal ageing and external stresses were summarized, which provides theoretical bases to research and develop advanced processes, such as laser processing, mechanical alloying, ultra-precision cutting, electropulsing etc. for surface materials science and thin films of alloys and functional semiconductors.
