Abstract
A preparation method of magnesium-aluminum-zinc-yttrium magnesium alloy semisolid slurry is characterized by comprising the steps of heating a magnesium-aluminum zinc alloy to 750 DEG C, adding a blocky magnesium-yttrium intermediate alloy wrapped by aluminum foil into melt after 20min, performing ultrasonic treatment for 1min to allow rare earth to be uniformly distributed in the melt, putting a magnesium-aluminum-zinc-yttrium rare earth magnesium alloy in a heat treatment furnace for isothermal heat treatment in an argon environment at 555-569 DEG C, keeping warm for 20-40min, taking out, performing water quenching, and obtaining the fine spherical semisolid rare earth magnesium alloy slurry. The magnesium-aluminum-zinc-yttrium rare earth magnesium alloy obtained by the method is uniform and round in semisolid structure, and the method is simple, safe and reliable in technology and convenient to operate.
Description
Technical field
The invention belongs to technical field of material, specially refer to a kind of method for preparing semi solid slurry.
Background technology
Magnesium alloy is the lightest structural metallic materials, and its density is little, and specific rigidity and specific tenacity are high, and has good heat conductivility, capability of electromagnetic shielding, damping capacity, machinability and damping performance.Therefore, magnesium alloy is called the green engineering material of 21 century, has important value and application prospect widely in aerospace, automotive industry and electronics and IT products field.
Along with the development of processing technology, the semi-solid processing method becomes the research hot topic of metal current material processing technique with its near-net-shape, the good advantages such as drip molding mechanical property, reduction energy consumption and raising die life.The research that at present both at home and abroad thermal treatment prepares magnesium alloy ingot for semi-solid isothermal is system not still, and major part is confined to the observation of microstructure evolution, for the research of microequilibrium, also seldom relates to.Semi-solid isothermal thermal treatment (Semi-Solid Isothermal Heat-Treatment is called for short SSIT) is a kind of method of the mid-90 in 20th century newly-developed, it has omitted step prepared by the semisolid non-dendritic blank, but realize semisolid non-dendritic in the post bake process before semi-solid-state shaping, its technological process is simple, with low cost, therefore paid close attention to by people.
