Characterizations of Zn-Al Alloys with Trace Element Interactions additions
Overview
This project investigates the interactions between trace elements and their effects on the quality and refinement of Zn-Al alloy. It will monitor changes in metallurgical phase transformations during solidification to assess the degree of modification and grain refinement. Additionally, this work will examine the effects of trace element interactions on the alloy’s microstructure and its ability to react with primary alloying elements to form beneficial compounds during solidification. These interactions significantly impact the alloy's mechanical properties and castability, aiming to develop a novel alloy with enhanced metallurgical properties suitable for high-performance alloys for automotive applications.
This project will focus on the metallurgical properties of Zn-Al alloys modified through trace element interactions. The chemical composition plays a critical role in determining the properties of cast alloys, with each trace element influencing the alloy structure individually or in combination with others, affecting the overall alloy performance. This study aims to understand how trace element interactions impact the modification and grain refinement of Zn-Al alloys by monitoring phase transformations during solidification.
Metallographic examinations using Scanning Electron Microscopy (SEM) and Optical Microscopy (OM) will link thermal analysis results with the corresponding microstructures. To evaluate mechanical properties, hardness, wear resistance, and tensile tests will be conducted. Furthermore, the corrosion behaviour of Zn-Al alloys with varying trace element concentrations will be assessed. The expected outcome is to develop a high-strength Zn-Al alloy that surpasses existing materials in bearing applications.
The research will establish a foundational understanding of three high-strength Zn-Al alloys to validate them for bearing applications:
1. Evaluate the optimum concentration of trace elements for modifying and refining Zn-Al alloy microstructure.
2. Investigate the influence of trace element interactions on high-temperature wear resistance using radial journal bearing wear tests.
3. Assess the effects of trace element interactions on mechanical properties and corrosion resistance.
4. Correlate the effects of various trace elements on tensile and hardness properties with microstructural characteristics and thermal analysis.
