| As a crucial precision forming method in the aerospace manufacturing industry, forging process is widely used in mass production of structural parts for large aircraft and rockets. The production quality of the forgings is often highly demanded, and the huge energy consumption of forging process directly affects the economic benefits of enterprises and indirectly causes many environmental pollution problems. To strive for the early realization of China’s “carbon peaking and carbon neutrality” and continuously advance the transformation of the manufacturing industry and the adjustment of the energy structure, it is urgent to take energy-saving measures on the basis of ensuring the quality of forgings. Focusing on the defects and core quality requirements of large forgings in aerospace, especially for aluminum alloy and other metals, the forging production process was divided into five main stages:raw materials, preparation, heating, forging, post-forging heat treatment, and the potential forging defects, their causes, and the resulting impacts were summarized step by step. In addition, the current research status of detection methods for quality requirements such as appearance quality, mechanical performance, crystallite size/average grain size, fracture toughness, residual stress, and corrosion resistance was systematically clarified to provide guidance for the crucial quality detection research of large forgings made of metals like aluminum alloy. Simultaneously, considering the extensive energy consumption characteristics of the forging process for large metal components, energy consumption detection methods were explored at three levels:factory, equipment, and product. The methods provide a theoretical research thought on improving energy efficiency, and offer guidance for achieving energy-saving goals in the aerospace sector’s large forgings. The theoretical approach plays a crucial guiding role in key quality and energy consumption detection of large metal forgings represented by aluminum alloy in the transformation and development of high-quality, low-consumption manufacturing in the forging industry. |
