| 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 | CURE CHARACTERISTICS OF HYDROXYL TERMINATED POLYBUTADIENE PREPOLYMER WITH BLOCKED TOLUENE DIISOCYANATE-Ⅰ显示文摘Controlled release of TDI and hence the cure characteristics of several blocked TDI with HTPB are reported. The reactions were followed through viscosity measurements as a function of time and temperature under the catalytic influence of triethylamine. The effect of nature of substituents present on the end capping substrate, temperature, solvent, basicity of catalyst and kinetics thereon have been studied. | Prathima Kamath M.Srinivasan V.N.Krishnamurthy | 1993 | Chinese Journal of Polymer Science1993，11，3： | 1 |
| 4 | A NEW POLYMERIC FLAME RETARDANT ADDITIVE FOR NYLON显示文摘The present paper deals with the use of a new polymeric flame retardant material, polyphenylene sulphide (PPS) for plastics. Incorporation of 15—20% PPS into nylon-6 has provided UL V-0 rating for the system and there is enhancement in tensile and flexural properties. The results obtained on the thermal, crystallization and flow characteristics of the nylon-PPS system upto a loading of 40% PPS are also discussed. | M.SRINIVASAN R.VASANTHAKUMARJ P.T.UTHIAH | 1993 | Chinese Journal of Polymer Science1993，11，1： | 0 |

| 6 | CURE CHARACTERISTICS OF HYDROXYL TERMINATED POLYBUTADIENE PREPOLYMER WITH BLOCKED TOLUENE DIISOCYANATE-Ⅱ显示文摘Cure characteristics of hydroxyl terminated polybutadiene (HTPB) prepolymer with avariety of blocked toluene diisocyanate (TDI) in the presence of triethylamine (TEA) andchloroacetic acid catalyst are reported. Phenol, thiophenol, p-chloropheno1, p-nitrophenol,p-cresol, resorcinol, naphthols, caprolactam and butylated-hydroxytoluene were used as blockingagents. Viscosity measurements have been carried out using a mixture of HTPB and blocked TDIin cyclohexanone in the presence of the catalysts at 50℃ and 60℃ using Haake rotational vis-cometer. Viscosity measurements have also been carried out with 50% solids such as ammonium sulphate along with HTPB and TDI adduct. | Prathima Kamath M.Srinivasan V.N.Krishnamurthy | 1994 | Chinese Journal of Polymer Science1994，12，1： | 0 |
