Abstract

Abstract

Effect of Bi content on microstructure,mechanical properties and cutting property of lead-free brass alloy has been studied.Result of SEM,EDS and XRD shows that the alloy is comprised with α phase and β phase,some part of Bi exists in β phase and phase boundaries.Brinell hardness,tensile strength,yield strength and cutting property are promoting,while elongation percentage and percentage reduction of area are decreasing as content of Bi is increasing.Alloy 2# with 0.7% Bi is with appropriate mechanical properties as Pb-brasses.
