Abstract

Melt spinning technique was used to prepare lead-calcium alloys without\ with adding different
aluminum ratio (1,3,5 wt. %). Also they study microstructure, corrosion resistance, electrical resistivity, elastic
modulus, internal friction, Vickers hardness and thermal properties of these alloys using available
experimental techniques. Microstructure analysis shows that, the formed phases and matrix structure of leadcalcium alloy changed with increasing calcium content or adding different aluminum ratio (1,3,5 wt. %). Also
all measured physical properties such elastic modulus, Vickers hardness, internal friction, melting point,
electrical resistivity values and corrosion parameters of lead- calcium alloy varied (increased\ or decreased)
with increasing calcium content or adding different aluminum ratio (1,3, 5 wt. %).
