The invention relates to a method for manufacturing an aluminum-
silicon target material. The method comprises the following steps of: providing an AlSi
ingot casting step, a drawing step, a primary upsetting step, an intermediate heat treatment step, a secondary upsetting step, a preheating treatment step, a calendaring step and an annealing heat treatment process step, wherein cold drawing operation is used in the drawing step, and a
forging ratio X1 in the cold drawing operation is gerater than or equal to 1 and less than 2; in the primary upsetting step, a
forging ratio X2 is greater than or equal to 2 and smaller than 3, and cold heading operation is used for primary upsetting; in the intermediate heat treatment step: a product is kept within a first preset temperature range, and is quickly put into cold water after being subjected to heat preservation for first preset time; in the secondary upsetting step, a
forging ratio X3 is greater than or equal to 2 and smaller than 3, and cold heading operation is used for secondary upsetting; in the calendaring step: multi-pass calendaring is performed on the product, and reducing rolling reduction along with increase of calendaring passes; and in the annealing heat treatment process step: in an annealing temperature range, heat preservation is performed for third time, and
water cooling treatment is performed to form a final targetproduct. According to the method, the forging ratio is reasonably controlled,
water cooling is adopted for cooling, so that
Si element precipitation is reduced, and therefore the
microstructure and the
machining performance of the target material are guaranteed.
