Effects of Swaging and Aluminium Content on the Microstructure and Mechanical and Sliding Wear Properties of Zinc-Based Alloys

Abstract

An attempt has been made to examine the influence of swaging on the microstructure, mechanical properties and sliding wear characteristics of some zinc-based alloys comprising varying concentrations of aluminium. The density of the alloys decreased with aluminium content while hardness followed a reverse trend. Further, the aluminium concentration in an intermediate range (close to 27.5%) led the alloy system to attain maximum tensile properties and sliding wear resistance. Swaged specimens exhibited properties superior to their as-cast variety irrespective of the test condition and aluminium content.
