γ/γ′ interface strengthening of Re in single crystal superalloys LUO Yu-shi(骆宇时), LI Jia-rong(李嘉荣), LIU Shi-zhong(刘世忠), HAN Mei(韩 梅), CAO Chun-xiao(曹春晓) National Key Laboratory of Advanced High... electron microscopy (HRTEM) technique was used to detect the structure characteristic of γ/γ′ interface. The interfacial dislocations of γ/γ′ were analyzed with TEM. The results show that as Re......
determined by the interface properties between composites and existing concrete [13, 20]. Regarding FRP, many scholars have investigated the interface properties [20-22]. TUAKTA et al [20] studied... for predicting the service-life of FRP-concrete bond systems.LI et al [21] found that the FRP-concrete bond strength was related to the number of dry-wet cycles and that the interface bond strength......
