In this study, powder metallurgical Cu-Ni-Si alloys with different Ni:Si ratios are produced by cold pressing sintering (600 MPa, at 950?C for 60 min) and bulk materials solution annealed min, quenched in water aged 450?C min. A fine distribution of Ni-Si compounds embedded a netted-free structure is formed the matrix. Although conductivity level least 22% IACS achieved all alloys, impurity eff...

Abstract The CaSi nanowires were synthesized on Si substrate by reactive deposition technique. A great amount of Ca vapor reacted with surface cleaned substrate, and was grown the as-synthesized film. diameter could achieve a minimum value about 25 nm. nanowire self-orient along <001> direction. We can control length experimental parameter settings, such as quantity source, duration time ...
