The invention provides a complex
metal thin-wall component and an additive and equal-material collaborative manufacturing method thereof. The method comprises the steps that firstly, according to the service
performance requirement of the component, performance requirements of different areas are analyzed, filling analysis is conducted, and a near-net-shape prefabricated blank model is designed; then, a prefabricated blank is constructed in a
metal additive manufacturing mode, and regional regulation and control of a
microstructure are achieved by regulating and controlling technological parameters; after heat treatment, the preformed blank is loaded into a finish
forging die, integral
forging forming is completed under the high-temperature and high-pressure condition, and defect closing and structure homogenization are achieved; and finally, the
forge piece is subjected to finishing and secondary heat treatment, and the
mechanical property and the service reliability are optimized. The method has the advantages of design flexibility and
forging densification of additive construction, has the characteristics of high blank making efficiency, high material
utilization rate, controllable
structure property, wide applicable material and process range and the like, and is particularly suitable for rapid and high-quality manufacturing of complex-configuration
metal components with staggered ribs, uneven wall thickness and the like.
