Numerical simulation of sequential collision behavior of multi-particles during dynamic formation of Al-based coating on magnesium alloy by supersonic particles deposition demonstrated that continuous tamping effect from subsequent sprayed particles improved significantly compression ratio of former deposited particle and promote effectively deformation and spread out. Analysis to morphology and microstructure of Al-based coating on magnesium alloy by SEM and TEM elicited that subsequent sprayed particles generated two effects including erosion and compaction to former deposited layer of the coating, induced formation of high density dislocation, grains refinement and re-crystallization, which played work-hardening strengthening effect and fine crystal strengthening effect to Al-Si coating.

The process of twin-roll casting including pouring, solidifying, rolling and cooling can be accomplished in a very short time. Consequently, some important process parameters in the twin-roll casting that are difficult to be obtained in experiment can be acquired using numerical simulation. In this paper, a numerical simulation based on a 2D finite element model of vertical twin-roll strip casting of magnesium alloy has been conducted, and the thermal stress fields are significantly discussed. The influences of key process parameters consisting of submerged nozzle depth and nozzle spray angle have been studied. The thermal cracks on the surface of the strip are analysed according to the thermal stress distribution.
