Beschreibung
Zusammenfassung:	The invention discloses an alloy multi-scale strengthening phase in-situ precipitation regulation and control method and an alloy casting, and belongs to the technical field of metal preparation. An alloy melt is contained in a crucible of casting equipment, and the periphery and the lower portion of the base plate are filled with a liquid cooling medium; the alloy melt is sprayed out of an outlet of the crucible and impacts on the base plate, and under the spreading and flowing effects of the melt and the cooling effect of the base plate and the liquid cooling medium, regulation and control of a submicron-level precipitated phase and forming of an alloy solidification layer are achieved; the substrate is moved downwards by a certain distance towards the liquid cooling medium; and the above processes are repeated, so that the alloy melt is continuously stacked and formed on the alloy solidification layer, it is ensured that the alloy solidification layer is subjected to a certain number of times of thermal cy
