Microstructure parameters, such as primary dendrite arm spacing (lambda(1)), secondary dendrite arm spacing (lambda(2)), and dendrite tip radius (R), were measured. The microhardness (Hv) and ultimate tensile strength (sigma) of the directional solidification samples were also measured. The influences of solidification and microstructure parameters on Hv and sigma were investigated. The results obtained in this work were compared with similar experimental researches in literatures. It is shown that the Hv and sigma values increase with the increase of G and V, but decrease with the increase of lambda(1), lambda(2), and R.eninfo:eu-repo/semantics/closedAccesslead-antimony alloydirectional solidificationmicrostructuremechanical propertiesArticle18558258810.1007/s12613-011-0481-22-s2.0-83255184623Q1WOS:000295434900012Q2
