. However, the TEPMC and TEHPDC alloys have similar tensile strength around 67 MPa at 350 °C. Due to the coarsening of eutectic Si, the TEPMC alloy exhibits better creep resistance than the TEHPDC... rates of the alloys after thermal exposure are higher than those of the as-cast alloys, indicating that the reduction in creep resistance occurs after thermal exposure. In addition, the minimum creep......
J. Cent. South Univ. (2012) 19: 252-261 DOI: 10.1007/s11771-012-0999-0 Creep properties and permeability evolution in triaxial rheological tests of hard rock in dam foundation XU Wei-ya(徐卫亚)1, WANG... ? Central South University Press and Springer-Verlag Berlin Heidelberg 2012 Abstract: Triaxial creep tests were carried out under seepage pressure by using rock servo-controlled triaxial rheology testing......
corrosion resistance but also form a stable Mg2Sn compound with Mg; 2) Ca can also improve creep resistance by forming stable Mg2Ca intermetallic particles with Mg; 3) Sn, Ca and Mg can form the CaMgSn... that, although the CaMgSn phase in the Mg-3Sn-2Ca magnesium alloy shows high thermal stability, its coarse morphology deteriorates the creep resistance of the alloy, acting as crack initiation sites[6......
a stable Mg2Sn compound with Mg, and Ca can improve creep resistance by forming stable Mg2Ca intermetallic particles with Mg[4-5]. In addition, Sn, Ca and Mg can form the CaMgSn phase which has higher... Comparison of as-cast microstructure, tensile and creep properties for Mg-3Sn-1Ca and Mg-3Sn-2Ca magnesium alloys YANG Ming-bo(杨明波)1, 2, CHENG Liang(程 亮)1, PAN Fu-sheng(潘复生)2 1......
TENSILE CREEP DEFORMATION AND DAMAGE BEHAVIOR IN A NICKEL-BASE SUPERALLOY AT 900℃ H.C.Yu1,H.C.Yang2,S.S.Xie3 (1.Beijing Institute of Aeronautical Materials, Beijing 100095, China;2.College of Materials and Metallurgy, Northeastern University, Shenyang 110004, China;3.R & D Center, Baosteel Co.

of the precipitated O phase was also increased, and the length was shortened. The creep resistance of this alloy was relevant to the morphology and volume faction of the lamellar O phase. The increase of lamellar... and oxidation resistance. These become the major obstacles for the application in the aerospace industry. Hence, it is rather important to improve the oxidation and creep resistance of the Ti-22Al-25Nb alloy......
corrosion resistance of CAF components. In addition, the electrical conductivity of RRAed-24 h sample first declines and then increases with the time in both creep aging and stress-free aging... and re-aging treatment can improve the forming efficiency and stress corrosion resistance of CAF components. However, elongation of the creep aged AA7150 declines when the re-aging time exceeds 24 h......
