(a) that the criterion of CST to solidification crack of 5083 Al-Mg alloy[1] increases up to 9.69×10-3(%/℃) with slow bending speed from a mini value that is hard to measured with fast bending speed. 6082 alloy... of elevated tempera- ture cracking of different materials 1) Ultrahigh temperature tensile test in ZL101 alloy During tensile test at 580 ℃, two kinds of low melting point eutectics, Al-Si and Al-Mg2Si......
of as-cast 7075 alloy, and the optical addition of Al2O3p is 2 wt%. The primary α-Al becomes uniform and orderly, and the Mg(Zn,Cu,Al)2, Al7Cu2Fe phases are refined. After hot extrusion, the Mg(Zn,Cu,Al)2...), and transmission electron microscopy (TEM). The experimental consequences reveal that the optimal addition of Al2O3p was 2 wt%. After hot extrusion, the Mg(Zn,Cu,Al)2 phases partially dissolve into the matrix......
