Based on this, a series of new forging processes are proposed, such as upsetting of tapered plate, LZ forging, FM forging method. From the thermodynamic point of view, the control of forging and grain size control were studied, and valuable low-pressure rotor steel technology was proposed. Some of the research results have been applied in production to obtain significant economic and social benefits. Some of the published papers have been cited by domestic and foreign abstracts and are highly praised by academics both at home and abroad. Acceptance of experts believe that: the research topic “is a cutting-edge areas of advanced manufacturing technology based on the subject,” the research results “to promote the development of disciplines.”
