The effects of high pressure and temperature environments on the properties of 6061-T651 aluminum

<p>"During this experimental testing program the effects of the simultaneous application of high pressure and temperature environments on the mechanical properties of 6061-T651 aluminum were analyzed. From the data obtained at the yield and ultimate points a yield and ultimate model was developed based upon the parameters effective stress, effective strain, and the hydrostatic component of stress. This model was obtained solely from the data acquired from uniaxial tensile specimen tested at various pressures and temperatures. Two other loading paths--biaxial tension and torsion--were then used to verify the accuracy of the model. From the testing program, data were also obtained for the effects of the pressure and temperature environments on the other material properties such as Young's Modulus, Poisson's Ratio, and ductility. The third objective of this testing program was to develop test fixtures which would be able to perform the required tests as well as to operate under the extreme environmental conditions"--Abstract, page iii.</p>
