In this paper, the development of rapid-solidified heat resistant aluminum alloys are reviewed, and the principle of compositional selecting, preparation methods and reinforcement mechanism are analyzed emphatically.

Lubrication action of pure aluminum during high temperature deformation of heat-resistant aluminum alloy;

Experimental investigation on forge forming process of spray deposited blanks of rapidly solidified AlFeX heat-resistant aluminum alloy;

Densification and mechanical properties of spray deposited large scale heat-resistant aluminum alloy tubular preforms during wedge pressing;

The heat flow of the depositing process in the course of the preparation of multi-layer spray deposited (MLSD) pipe blank of heat-resistant Al alloy was modeled.

This paper established a model for the heat flow of the atomization process in preparing the multi-layer spray deposited (MLSD) heat-resistant Al alloy pipe blank, and calculated the kinetic energy and heat transformation between the molten droplets and the atomization gas.
