  4. 8. Properties of Al-Mg Alloys and Vacancies in Al: a First-Principles Investigation

    Författare :Karin M. Carling; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Phase transformations such as precipitation are used to control the strength of many technologically important aluminum alloys. In precipitation hardening, the material is heat treated and aged to produce precipitates, small particles of a different phase, in the matrix. LÄS MER
