| Popis: | A high strength and toughness AZ63 cast magnesium alloy whose ultimate tensile strength, yield strength and elongation at room temperature respectively reached 319 MPa, 160 MPa and 7.6%, was developed by combining the alternating-temperature ultrasonic melt treatment and T6 heat treatment. The high as-aged tensile properties of the alloy with the alternating-temperature ultrasonic melt treatment are mainly attributed to the remarkable increase of the β-prismatic precipitates with orientation relationships (ORs) of ([Formula: see text]0)β // (1[Formula: see text]00)α, [[Formula: see text]11]β // [11[Formula: see text]0]α, thereinto the mentioned-increase is possibly related to that the solute-vacancy clusters along {0[Formula: see text]11} plane might serve as the nucleation points of the β-prismatic precipitates. |
