The influence of deformation temperature and strain rate on the steady flow stress of aluminium sheet used for easy-open cans prepared by synthetical technique of high-efficient melt-treatment of aluminium and homogenization during hot compress deformation was discussed.

Study on the steady thermal stress in the metal-ceramic composite plate with an interlayer of FGM under the mechanical boundary of ECBF;

The steady thermal stresses in the plate of a functionally gradient material (ZrO_2 and Ti-6Al-4V)(FGM) were analyzed by the finite element and Sinpson method.

The steady thermal stresses in functionally gradient material(ZrO_2 and Ti-6Al-4V)(FGM) plate with tempera-ture-dependent properties under differently mechanical boundary are analyzed by the nonlinear finite element method and the Sinpson method.

Through thermal simulation compression experiment of tank used aluminium alloy,the influence of rate of deformation and deformation temperature on rheological stress were analyzed.

20/s and at constant temperature in the range of 450～500 ℃ were conducted on the 35steel and 45steel on the basis of the rheological stress constitutive model of 20steel.

The experimental results indicated that the rheological stress was influenced by both strain rates and deformation temperature,and it increased with increasing strain and tends to be constant afte.
