Abstract:

Article Preview

Cast magnesium alloys are constantly increasing used in the automotive and electronic industry because of the excellent performance. Squeeze casting is an innovative and energy-saving manufacturing process which can be used to produce near net-shape magnesium components. In order to improve the quality of the squeeze casting,the different process parameters were adopted to study the forming property of AZ91D alloy by applying multifactor orthogonal test and analysis of range under the laboratory condition. The metal pouring and die temperatures considered in the investigation were within the range of 680-780 and 300°C respectively. The results showed that the samples’ synthetic mechanical properties was the best, and squeeze casting can refine grain and the second phase particle β(Al12Mg17)separated out more by using mechanical properties test and analyzing microstructure when casting temperature is 730°C, squeezing force is 100 Mpa and time of keeping forces 25s.
