Abstract
Heavily deformed in-situ composite wires based on aluminum were produced through a powder metallurgy process to avoid interfacial reaction. Metal filaments get finer and closer together as the drawing strain increases. Mechanical properties such as tensile strength were evaluated with particular interests on relationships with microstructures. Tensile strength increases to 1063 MPa at a drawing strain of 14.6, which is the maximum drawing strain in this study. The dependence of ultimate tensile strengths of the composites on the mean filamentary spacing is investigated. There is a good correlation with the Hall-Petch type relationship. This result suggests that the filaments act as barriers against dislocation motion, and that shear modulus of the second phase barrier is a predominant parameter for the strengthening of the wires.
