Cyclic pressing is a new kind of densification processing, which is introduced to densify as - deposited ring of al - 20 % si / sicp. this paper includes the densification result and rule of this technics. the research shows that this technics can be successfully used to densify spray - forming porous material and can be availably adopted to improve mechanical performance and microstructure. this technics is characterized by simple equipment 、 small expense and flexible process, and these characters will make it come true to producing spray - deposited rings less costly
本文採用一種新型緻密化工藝?楔壓工藝?對噴射沉積al - 20 % si / sicp大環進行了緻密化加工，採用密度硬度分佈、抗拉強度變化和檢測顯微組織變化的實驗研究方法對其緻密化效果及該工藝規律進行了研究，通過研究表明了楔壓工藝可以成功地用來緻密化噴射沉積多孔材料，該工藝有效地提高了噴射沉積大環件的緻密度和抗拉強度並改善了組織。 -
The approximate polynomial method was based on neuber ' s method, the cyclic stress - strain responses and neuber ' s rule were treated as probabilistic curves, and the statistic characteristic was obtained from the approximate polynomial. the method is fast and easy for engineering application
