摘要

Upward directional non-steady-state solidification experiments have been performed on a hypomonotectic Al-5.5 wt%In alloy. The alloy developed cellular as-solidified microstructure for tip growth rates, V L, higher than 0.95 mm/s. The casting regions associated with V L  0.95 mm/s were shown to be characterized by a microstructure formed by In droplets disseminated in the Al matrix. Tip growth rate and microstructural features, such as cell spacing and interphase spacing, have been experimentally determined. The experimental cell spacings have been compared with theoretical predictions furnished by the Hunt-Lu model. It was found that the experimental scatter lies below the minimum range of values theoretically predicted. Moreover, the experimental cell spacing evolution with V L is characterized by a −1.1 power law. The droplets’ interphase spacing, λ, is related to the growth rate by the Jackson-Hunt relationship (λ 2 V L = constant).View full textDownload full textKeywordssolidification, monotectics, interphase spacing, cell spacing, Al-In alloyRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/09500839.2012.685962
