Microstructure and properties of semi solid magnesium alloy
Abstract：In twenty-first Century there are many emerging technology, which is good for the development of new technologies, including semi solid metal processing technology is one of the near forming technology. However, magnesium alloy as a green engineering material, combined with semi solid forming technology to solve the solution of magnesium alloys due to the ease of oxidation and burning, conventional processing difficulties, quality is difficult to control the problem and it has a lot of excellent performance, has a decent performance in many fields. This paper mainly for everyone on summarize the basic properties of semi solid forming magnesium alloy organization, including semi solid forming principle, technical characteristics; semi solid metal features; including an overview of relevant
Keywords: semi solid, magnesium alloy, semi solid forming
