德国金属学会挤压专业委员会对本研究工作甚感兴趣,这里报告的就是该会所做的工作。由此便能反映出当前挤压形变工艺的水平(从金属学的观点来看),同时又从理论和实践的结合上对挤压设备、生产工艺、形变技术以及生产的经济性等进行评述。(限 The German Institute of Metallurgy squeezes the professional committee very interested in this research, here is the report of the work done. This will reflect the current level of extrusion deformation process (from the metallurgical point of view), while the combination of theory and practice of the extrusion equipment, production technology, deformation technology and production of economy, etc. were reviewed .
