The Influence of Substructure on the Properties of Metals.
Abstract
There have been numerous studies concerned with thermomechanical processing (TMP) of 7000 series (Al-Zn-Mg-Cu) and 2000 series (Al-Cu-Mg) aluminum alloys. The ultimate goal of these studies has been to develop the ability to tailor a material's microstructural characteristic through TMP and composition control to improve a variety of properties. In this investigation the influence of TMP on several commercial alloys and compositional modifications based on them has been studied relative to their resulting tensile and creep properties. The benefits of TMP for high-temperature strength must be gained by creating a strong microstructure that is stable during long exposure to elevated temperatures under stress. The elements of the microstructure subject to modification are the grain size and shape, the precipitate composition, morphology and distribution, and the dislocation substructure.
