Abstract
This study was performed on a hot extruded titanium alloy (Ti6Al4V) of circular cross-section. The alloy was deformed at different temperatures and strain rates using the uniaxial tension test. Subsequently, a comprehensive microstructure analysis using an electron back-scattered diffraction technique was performed to investigate the microstructure of the alloy. The study revealed the formation of hard-orientated regions during deformation that adversely affected the ductility of the alloy. This study also highlights the reasons responsible for the evolution of hard orientations at different temperatures.
期刊介绍:
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
