Magnesium alloy melt modification techniques Cade Dongguan Sheng magnesium alloy melting magnesium alloy material deterioration aim is to change the organizational form of magnesium alloy, the process has a greater impact on the grain size and mechanical properties of the alloy and magnesium fluid inclusions have a certain influence oxidation. Studies have shown that magnesium alloy die-casting process, Guangdong, for magnesium alloy die-casting magnesium alloy Al-free manufacturing, using zirconium modification has good grain refinement effect principle is Zr peritectic reaction occurs to promote grain refinement . After the addition of a suitable carbon material in Mg-Al alloys in it with alloy liquid from a chemical reaction A1C4, the compound can play a role in foreign nuclei magnesium alloy die casting parts, prompting the grain refinement of magnesium alloys . Add mixed rare earth based on different levels of AZ91 magnesium alloy on its organization and properties of cast and solution and aging also have a significant effect. Dongguan Sheng Cade magnesium alloy heat-resistant magnesium alloy magnesium alloy poor hinder widely magnesium alloy die-casting process, one of the main reasons, when the temperature rises, its strength and creep resistance dropped significantly, so It is difficult as the key parts (such as engine parts) material to be more widely used in the automotive and other industries. Heat resistant magnesium alloy has alloying elements in the development of rare earth elements are mainly used (RE), and silicon (Si). Rare is an important element to improve the heat resistance of magnesium alloys. Containing rare earth magnesium alloy QE22 and WE54 have fairly high temperature strength aluminum alloy, but the high cost of rare earth alloy is a major obstacle that is widely used. Magnesium alloy die casting process, Cade Sheng (certified), magnesium alloy die-casting process is provided by Cade Sheng Technology Co., Ltd. of Dongguan City. Sheng Technology Co., Ltd., Dongguan City, Cade (www.kadesn.com) is Dongguan, the other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
