| 1 | Physical,Mechanical,and Tribological Attributes of Stir-Cast AZ91/SiC_p Composite显示文摘In the present investigation,composites with silicon carbide particle(SiCp) as reinforcement and AZ91magnesium alloy as matrix have been synthesized using liquid metal stir-casting technique with optimized processing conditions.The composites with good particle distribution in the matrix,and better grain refinement and good interfacial bonding between the matrix and reinforcement have been obtained.The effect of SiCpcontent on the physical,mechanical,and tribological properties of Mg-based metal matrix composite(MMC) is studied with respect to particle distribution,grain refinement,and particle/matrix interfacial reactions.The electrical conductivity,coefficient of thermal expansion,micro-as well as macro-hardness,tensile and compressive properties,and the fracture behavior of the composites along with dry sliding wear of the composites have been evaluated and compared with the base alloy. | K.K.Ajith Kumar Abhilash Viswanath T.P.D.Rajan U.T.S.Pillai B.C.Pai | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，2： | 8 |
| 2 | Investigation on mechanical properties and creep behavior of stir cast AZ91-SiC_(p) composites显示文摘The room temperature mechanical properties and high temperature creep behavior of AZ91 alloy reinforced with SiC_(p) synthesized via stir casting have been evaluated.The mechanical properties showed improvement with respect to the amount of reinforcement content.The creep testing of the composites carried out at a temperature of 175 ℃ under constant stress of 80,100 and 120 MPa reveals different creep characteristics depending upon the reinforcement content and the applied load.The true stress exponents of different composites calculated from minimum creep rate indicate the possible mechanisms of creep deformation. | Abhilash Viswanath H.Dieringa K.K.Ajith Kumar U.T.S.Pillai B.C.Pai | 2015 | Journal of Magnesium and Alloys2015，3，1： | 3 |
