Abstract
The casting processes and casting defects in several high strength and heat resistant cast magnesium alloys are reviewed in this paper. These alloys can be fabricated by sand casting, permanent casting, investment casting, low pressure investment casting and thixoforming. The formation mechanism of casting defects such as hot tearing and porosity and their influence on mechanical properties are similar to other alloys. The relationship between porosity and mechanical properties was also established.
