Tiffs paper briefly introduces the preparation technology of micro-layer composite material by the Electron Beam Physical Vapor Deposition (EBPVD) tecinique. Taking the advantage of the large-scale commercial software of Finite Element Analysis, a reasonable physical model was built up during the deposition processing and the distribution of residuul stress was analyzed between substrate and deposition layer or among deposition layers. The results show that: with the increasing substrate preheating temperature, the interlaminar shear stress increases but the axial residuul stress decreases. And the probability of curling up after de-bonding tends to enhance as the thickness of deposition fihn increases.

Microlaminates with alternating layers of Ni and Ni3A1 were fabricated by using EB-PVD method. The influences of deposition rates and substrate temperature on morphology of the microlaminates were investigated. The results showed that in order to produce Ni/Ni3A1 microlaminate with lower porosity and prevent the formation of columnar grains, higher deposition rates and substrate temperature were required. The mechanical properties of the microlaminates were examined using tensile tests. The fracture behavior was temperature and interlamellar spacing dependent, with a lower tensile strength at higher temperature or with larger ingerlamellar spacing.

The influence of the oxygen pressure on the phase composition, microstructural evolution of the combustion products during the combustion synthesis of zinc ferrite through iron, iron oxide, and zinc oxide powders was discussed. The results show that with the increase of oxygen pressure, combustion temperature and combustion wave velocity increase. Single spinel-phase zinc ferrite can be obtained when the oxygen pressure is 1.0MPa and a non-stoichiometric composition, Fe1-xO or Fe1-zO is formed when the oxygen pressure is below 1.0MPa or above 1.5MPa. Moreover, an analysis of the dependence of the degree of conversion to ferrite, η, on the oxygen pressure has also been made. For a given porosity and combustion temperature, the degree of conversion increases with the oxygen pressure increasing and for any given porosity and degree of conversion, higher pressure is required at higher temperature.
