Alloy multi-scale strengthening phase in-situ precipitation regulation method and alloy casting

This invention discloses a method for controlling the in-situ precipitation of multi-scale strengthening phases in alloys and an alloy casting, belonging to the field of metal preparation technology. The method involves placing molten alloy in a crucible of a casting equipment, with a liquid cooling medium filling the area around and below a substrate. The molten alloy is ejected from the crucible outlet and impacts the substrate. Under the spreading and flowing action of the melt, and the cooling effect of the substrate and the liquid cooling medium, submicron-level precipitates are controlled, and a solidified alloy layer is formed. The substrate is then moved downwards towards the liquid cooling medium by a certain distance. This process is repeated, allowing the molten alloy to continuously accumulate and form on the solidified alloy layer. This ensures that the solidified alloy layer undergoes a certain temperature and number of thermal cycles before entering the liquid cooling medium, achieving the control of nanoscale strengthening phases and the formation of the alloy casting. This invention controls the solidification and solid-state phase transformation process of the alloy through a layering method. The process is short, the strengthening phase control effect is good, and high-quality, high-performance alloy castings can be obtained.
