Abstract
This study aimed to exploit the potential of the ball-milling method to create a super-saturated solid solution in an immiscible Cu–Co system. The nanocrystalline binary 50Cu–50Co (at%) and ternary 50Cu–40Co–10Ti (at%) alloys produced by ball milling for up to 50 h and afterwards isothermal annealing are examined for microstructure and magnetic characteristics. Ti addition’s effects on solid solubility of Co in Cu morphology and magnetic characteristics of the systems were evaluated using cutting-edge techniques, such as X-ray diffraction, differential thermal analyzer, high-resolution transmission electron microscopy and superconducting quantum interference device. The thermodynamic stability of the solutions was assessed using DTA measurement at temperatures ranging from 450 to 650°C. The magnetic value of the ternary alloy after annealing increased up to 550°C before declining to 650°C.
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.
