Development of aluminium-tin alloy for high strength application

Abstract

This study looks into the preparation of an aluminium-tin alloy for high strength applications. The aluminium base metal was melted using a gas-fired lift-out crucible furnace. The basic aluminium (>99% Al) was melted first, and the control sample was cast into one of the prepared moulds at 710 °C. This inquiry was divided into two stages, the first being casting manufacture and the second being experimental testing. In the first stage, a set amount of aluminium and tin ingots were placed within a massive crucible and melted at temperatures of 710 °C, which is somewhat higher than the melting temperature of aluminium (680 °C). The investigation's second phase entails analyzing the microstructure and properties of the product. The investigation's main focus was on the tensile strength, metal composition, and mechanical characteristics of the aluminium-tin alloy. Tensile specimens of ASTM standards were prepared in the longitudinal direction and tested using a Universal Testing Machine to ascertain the tensile strength (UTM). Micro hardness was assessed using a Brinell Hardness Tester. In order to determine how the alloys' metal composition manifested itself in their microstructure, the optical microscope and scanning electron microscope (SEM) observations of the alloys were mostly used.
