Abstract

The evolution of the microstructure and the change in the mechanical properties of samples made of aluminum alloys D1 and D16 cut from different areas of the blank obtained using the method of continuous vertical casting with simultaneous metal deformation in the solid-liquid state is explored. A diagram of the prototype installation to implement this process is provided. The methodology for preparing samples to study the structure in the areas of the ingot located in different sections of the crystallizer and solidified under various temperature and stress conditions is examined in detail. It is shown that the advantage of the proposed method deals with forming a fine-grained structure during crystallization resulting in superior mechanical properties of the metal. For aluminum alloys D1 and D16 produced using this method, the increase in tensile strength amounts to 20 and 18%, the yield strength is 40 and 39% higher, and the hardness is better by 28 and 26% respectively. The relative elongation is 2.5 times higher for both alloy grades.
