Effect of internal pressure on strength of hydraulically expanded jointsLIU Qiang,LIU Gang,and YUAN Shijian School of Materials Science & Engineering,Harbin Institute of Technology,Harbin 150001,China摘 要:To analyze the effect of internal pressure on the connection strength of hydraulically expanded joints,a hydraulic expanding and push-out process......
stable oxide at oxidation temperature. From the viewpoint of thermodynamics, preferential oxidation plays the first role in internal oxidation. The oxygen partial pressure of the working medium.... The thermodynamic condition of the internal oxidation of Y is as follows: where is the required oxygen partial pressure when Y is oxidized. The threshold of oxygen partial pressure......

Article ID: 1003-6326(2005)02-0414-05 Influences of post-annealing and internal stress on magnetoresistance properties of Ni80Fe20 films GAO Yan-qing(高艳清), WU Ping(吴 平), CAI En-jing(蔡恩静... 450℃. The internal stress in the films deposited on K9 glass is compressive and the resistance measurement shows that RM∥ is larger than RM⊥ in these films. However, in the films deposited at the same......
