| Abstract Scope |
To obtain a better knowledge of Cu-10Sn (wt. %) alloy fabricated by selective laser melting (SLM), specimens with different orientations were prepared and then vacuum annealed at 600℃ and 800℃. The composition, microstructures, mechanical, thermal and corrosion properties were investigated for both as-fabricated (AF) and as-annealed (AA) specimens. The AF specimens exhibit the smallest grain size and the highest compression strength compared with AA specimens, which is consistent with Hall-Petch equation. Thermal conductivity (TC) of the AF specimens is ~ 10% and over 20% higher than that of AA specimens annealed at 800℃ and 600℃, respectively, which can be ascribed to the two-phase constituents, lower porosity and nano-sized pores of the AF specimens. The corrosion rate of AF specimens is almost two times higher than AA specimens due to the different morphology of passive layer, intergranular corrosion and internal galvanic corrosion. |
