Effect of nano ZrO_2 crystal structure on copper matrix composite interface

DING Jian, ZHAO Naiqin, SHI Chunsheng, LI JiajunSchool of Materials Science and Engineering, Tianjin University, Tianjin 300072, China  
ZrO_2/Cu composite powder was prepared by in-situ chemical route, with which a nano ZrO_2/Cu composite material was prepared by powder metallurgy. TEM observation reveals that there are two crystal types of tetragonal and monoclinic Zirconia particles, and different interfacial characterizations exist between the different zirconia particles and copper matrix. With Ansys software, interfacial stress was simulated in zirconia with different crystal structures and copper matrix. The results show that the stress is easily concentrated in the tip of monoclinic Zirconia particles and cracks are easily brought than the tetragonal zirconia interface.
