This paper deals with the experimental method and solution for viscosity coefficient of solid alloy materials, such as, solid aluminum alloy Lc4. Standard creep specimen of f10mm with male screw ends were adopted, and groups of creep tests were carried out under high-temperature on RD2-3 type creep-machines. Tests under a constant temperature but different stress levels, and under a constant stress but different temperature levels were carried out. The effects of temperature and stress on strain and strain rate were analyzed. By putting the experimental data into the constitutive equation of the rheological model of viscoplastic material, the viscosity coefficients of the solid alloy materials under different temperature levels and stress levels were derived easily. They are similar to viscosity coefficient of non-Newtonian fluid. This experiment is simply to be operated, and the calculation is conveniently to be solved.
