超塑性变形已发展成为材料科学中的一门新的分支学科。但在理论上还有许多问题没有得到解决,有些则尚待进一步的完善。自1983年10月至1987年2月,吉林工业大学宋玉泉和赵军、张振军等人在超塑性拉伸、胀形、挤压的变形力学理论方面进行了较为系统的研究,并进行了某些相关的试验,研制成功了有关的实验装置。他们的研究工作获得了重要成果,取得了较大的进展。 Superplastic deformation has developed into a new branch of material science. However, there are still many problems in theory that have not been solved yet others have yet to be further improved. From October 1983 to February 1987, Song Yuquan, Zhao Jun and Zhang Zhenjun of Jilin University of Technology conducted a systematic study on the deformation mechanics theory of superplastic stretching, bulging and extrusion. Some related experiments, the successful development of the experimental device. Their research has achieved important results and great progress has been made.
