The evolution of dislocation configurations in a new Ni‐base single crystal superalloy, M4706, during tensile deformation at room temperature is characterised by transmission electron microscopy. Experimental results show that contrary to previous reports, numerous isolated superlattice stacking faults and extended stacking faults are formed in the slightly deformed specimens with and without tertiary...
Dislocations and stacking faults in unalloyed magnesium processed by equal-channel-angular-extrusion are investigated by transmission electron microscopy. Stacking faults as wide as hundreds of nanometers and complex dislocation configurations are revealed, which creates diffraction contrast that is challenging to interpret. To elucidate the dislocation interaction, atomistic simulations are conducted...
Summary form only given. Silicon carbide nanowires with junctions are considered to be of potential value in nanoelectronics. A simple method by catalyst-assisted vapor-liquid-solid reaction for producting Y-junction silicon carbide nanowires is described. The Y-junction silicon carbide nanowires are investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It...
Summary form only given. Large scale SiC/SiO2 nanowires have been synthesized on Si (100) by the reaction of methane with silica using iron as catalyst. The growth time was 10 mins and the growth temperature was around 1,250°C in a normal atmospheric pressure. Detailed investigation with scanning electron microscopy (SEM), energy-dispersed X-ray (EDX), X-ray diffraction (XRD) and transmission electron...
In this work, Fe65Co35 alloy which has maximum saturation magnetization (Ms) among all metal magnetic materials was chosen to make Fe65Co35-SiO2 granular films, and the magnetic properties in whole composition were studied. The results show that good high frequency soft magnetic films were obtained by carefully controlling the microstructure. A serious (Fe65Co35)x(SiO2)1-x granular films are fabricated...
