A model for construction of efficiency and stability maps of hot working processes in polycrystalline metallic materials using the Garofalo's equation

摘要

Has been developed a fast and easy method for to evaluate the efficiency of the process and some of posible stabilities situations in the hot workin process for the pollicrystalines metalics materials (p.m.m), by the obtained dates in the Garofalo's equation resolution for the steady state creep and for wide ranges of the work vriables, stress, strain rate and temperature. These method use the fit- ting parameters obtained for the equation mentioned and of their physical meaning. Has been develo- ped the numerical treatment form our previously developed "software" for the analysis f "creep", and we can obtained the efficiency energetic maps for the "creep" and the more generally advises areas for the hot working.
