| 1 | Experimental and numerical analyses of magnesium alloy hot workability显示文摘Due to their hexagonal crystal structure,magnesium alloys have relatively low workability at room temperature.In this study,the hot workability behavior of cast-extruded AZ31B magnesium alloy is studied through hot compression testing,numerical modeling and microstructural analyses.Hot deformation tests are performed at temperatures of 250℃ to 400℃ under strain rates of 0.01 to 1.0 s^(−1).Transmission electron microscopy is used to reveal the presence of dynamic recrystallization(DRX),dynamic recovery(DRY),cracks and shear bands.To predict plastic instabilities during hot compression tests of AZ31B magnesium alloy,the authors use Johnson–Cook damage model in a 3D finite element simulation.The optimal hot workability of magnesium alloy is found at a temperature(T)of 400℃ and strain rate(ε)of 0.01 s^(−1).Stability is found at a lower strain rate,and instability is found at a higher strain rate. | F.Abbassi M.Srinivasan C.Loganathan R.Narayanasamy M.Gupta | 2016 | Journal of Magnesium and Alloys2016，4，4： | 5 |
| 2 | AZ31B镁合金及其纳米复合材料的滑动磨损行为(英文)显示文摘采用复合铸造工艺制备AZ31B镁合金及其纳米复合材料,再对所得材料在350°C进行热挤压。采用标准的销-盘式摩擦磨损试验机对AZ31B镁合金及其纳米复合材料的室温滑动磨损行为进行研究。实验条件为法向载荷10N、滑移速度0.60~1.2m/s、滑移距离2000m。采用SEM观察来研究磨损表面的磨损机理。通过构建一个线性回归模型来研究试验参数对磨销磨损率的影响。与AZ31B镁合金相比,由于增强体的作用而导致的硬度增强使复合材料表现出低的磨损率。犁削、犁沟、分层和氧化构成混合的磨损机理。 | M.SRINIVASAN C.LOGANATHAN M.KAMARAJ Q.B.NGUYEN M.GUPTA R.NARAYANASAMY | 2012 | Transactions of Nonferrous Metals Society of China2012，22，1： | 4 |
| 3 | APPROXIMATE CONTROLLABILITY RESULTS FOR INTEGRO-QUASILINEAR EVOLUTION EQUATIONS VIA TRAJECTORY REACHABLE SETS显示文摘In this article,we study the approximate controllability results for an integroquasilinear evolution equation with random impulsive moments under sufficient conditions.The results are obtained by the theory of C0 semigroup of bounded linear operators on evolution equations and using trajectory reachable sets.Finally,we generalize the results too with and without fixed type impulsive moments. | A.Vinodkumar C.Loganathan S.Vijay | 2020 | Acta Mathematica Scientia2020，40，2： | 0 |
