Metallographic analysis plays a crucial role in understanding the microstructural characteristics and mechanical properties of titanium alloys. This comprehensive review aims to provide an in-depth examination of the various techniques and methodologies employed in the analysis of titanium alloys. The primary focus is on the microstructural evolution, phase transformations, and the influence of processing parameters on the final properties of these alloys. Techniques such as optical microscopy, scanning electron microscopy, and transmission electron microscopy are widely used to investigate the microstructure at different scales. These methods allow for the identification of various phases, such as alpha, beta, and their respective transformations, which are critical in determining the mechanical behavior of titanium alloys. Additionally, the review discusses the effects of heat treatment, cold working, and alloying elements on the microstructure and properties. Understanding these relationships is essential for the development of new titanium alloys with improved performance characteristics. The analysis also highlights the challenges associated with metallographic examination, including the difficulties in sample preparation and the need for precise characterization techniques. Overall, this review provides a comprehensive overview of the current state of metallographic analysis in titanium alloys, emphasizing the importance of these techniques in advancing the field of materials science.
