; accepted 17 November 2014 Abstract: The microstructure, the content of compounds, mechanical properties and fracture behavior of high vacuum die casting Mg-8Gd-3Y-0.4Zr alloy (mass fraction, %) under... according to microstructure results. The optimum ultimate strength and elongation of solution-treated Mg-8Gd-3Y-0.4Zr alloy are 222.1 MPa and 15.4%, respectively. The tensile fracture mode of the as-cast......
℃ for 24 h, is up to 765 MPa. Key words: aluminum matrix composite; spray deposition; heat-treatment; fracture morphology fracture strength of the as-aged sample is 765 MPa, which is much higher than that of the as-extruded and the as-solid-solution treated......
of the Mg-Li-X alloy to hot-rolling deformation is attributed at least partially to the insensitivity of residual stress and texture to hot-rolling. Key words: Mg-13Li-X alloy; residual stress; fracture... of 20 mm were machined according to GB/T228-2002, tensile tests were carried out on a ZD10/90 machine, and fracture surfaces of broken specimens were characterized by a SEM-S530 microscope. Residual......
