The lamellar spacings (lambda) and microhardness (H(v)) were measured from both the transverse and longitudinal sections of the samples. The dependence of the lamellar spacings (lambda) and microhardness (H(v)) on the temperature gradients (G) were determined by means of linear regression analysis. According to these results, the value of lambda decreases as the value of G increases and the value of Hv increases for a constant V. The results obtained in this work are compared with previous similar experimental results obtained for binary or ternary alloys.eninfo:eu-repo/semantics/closedAccessdirectional solidificationeutecticgrowth from meltalloysArticle14557558210.3365/met.mat.2008.10.5752-s2.0-55349141099Q1WOS:000260468100007Q1
