ABSTRACT A comparative study of Residual stresses and Distortion in cylindrical samples of Aluminum Alloy 7075-T6, quenched in aqueous solutions of PAG UCON A, with concentrations of 10, 20 and 30 % in water and under different conditions of agitation, is presented in this article. In order to discuss the comparative advantages of such aqueous solutions as quenching media with control of cracking and Distortion , the ABAQUS/Standard Finite Element Software was applied to assess such parameters during the heat treatment, with previous calculation of the heat Transfer coefficients as dependent of the temperature, by means of the INC-PHATRAN Code.
