Introduction Magnesium (Mg) alloys are light structural materials. They are used extensively in the design of components and parts of automotive and aerospace applications to comply with the strict legislations concerning emissions and energy consumption. There are several advantageous in using the Mg alloys in the design stated by Kiełbus (2006) , such as them being strong and lightweight, having a high strength-to-weight ratio, being recyclable as well as non-toxic. They Abstract This paper presents the study of the effects of the Magnesium Silicates on the crack initiation. The most fascinating part of this study is the propagation of the crack in magnesium alloys under a static load. Detailed fractography of the fracture surfaces of the cast Magnesium alloy revealed that the crack was initiated from silicon inclusion that had probably originated from the sand mould and had been washed throughout the casting on the advancing metal stream.
