| 1 | Mechanical and wear behaviour of Mg-SiC-Gr hybrid composites显示文摘The present research deals with development and characterisation of magnesium–SiC–Gr hybrid composites through powder metallurgy route.Morphology analysis of the magnesium and reinforcement powder particles has been carried out using particle size analyser(PSA)and X-ray diffraction(XRD),and then the mixed powders were analysed through scanning electron microscope(SEM).The developed composite exhibit increased hardness when compared to base material,which could be attributed to the presence of hard SiC.Furthermore,a slight decrease in hardness is observed for the hybrid composite when compared to Mg–SiC composite due to the presence of soft Gr particles.The tribological properties of the developed composite materials were investigated using pin-on-disc wear test apparatus under dry sliding conditions.The wear resistance of the developed composites improved significantly than that of the magnesium matrix due to the upright effect offered by both of the reinforcements.The SEM analysis was carried out on the worn out surfaces for better understanding of wear mechanisms.5%Gr reinforced Mg-10SiC composites confer better wear resistance among the developed composites. | K.Soorya Prakash P.Balasundar S.Nagaraja P.M.Gopal V.Kavimani | 2016 | Journal of Magnesium and Alloys2016，4，3： | 2 |
| 2 | 纳米银对铸态6061铝合金的组织、力学和摩擦性能的影响(英文)显示文摘利用搅拌铸造法制备不同含量纳米银(1%,2%)6061铝基合金,采用硬度、拉伸、压缩和磨损实验表征所制备的试样,并用布氏硬度试验机测试样品的室温硬度。随着合金化元素质量分数的增加,硬度明显增大。采用光学显微镜检测抛光样品,通过扫描电子显微镜进一步研究拉伸和压缩试件的断裂表面。与基体合金相比,铝-银合金的抗压强度、极限抗拉强度、伸长率和耐磨性有所提高。采用搅拌铸造技术得到了相对均匀和精细的组织,提高了熔融金属中增强材料的添加量。结果表明,最佳硬度组合6061铝-纳米银合金可取代传统材料,获得更优的性能和较长的寿命。 | G.PITCHAYYAPILLAI P.SEENIKANNAN P.BALASUNDAR P.NARAYANASAMY | 2017 | Transactions of Nonferrous Metals Society of China2017，27，10： | 1 |
