Structural features of near equiatomic FeCo-2V semi-hard magnetic alloy prepared by MIM technology
The structural properties of a magnetically semi-hard near equiatomic FeCo-2wt%V (FeCoV) alloy produced by Powder Injection Moulding (PIM) (option by fine metal powder - Metal Injection Moulding (MIM) technology) were investigated in this paper. Starting granulate was prepared by mixing FeCoV powder with a low-viscosity binder. After injection, the green samples were first treated with a solvent and then thermally with the same aim of removing the binder. MIM technology was completed by high-temperature sintering for 3.5 hours at temperatures from 1370 OC to 1460 OC in a hydrogen atmosphere, which provides the necessary magnetic and mechanical characteristics. The influence of sintering temperature was investigated concerning the aspects of the processes of structural transformation by the methods of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The appearance of an intense diffraction peak of the ?'-FeCo phase (crystal structure type B2) was registered for all investigated samples. Structural parameters particle size Dmax, Feret X, and Feret Y exhibit constant increase with increase of sintering temperature.
期刊介绍：
Science of Sintering is a unique journal in the field of science and technology of sintering.
Science of Sintering publishes papers on all aspects of theoretical and experimental studies, which can contribute to the better understanding of the behavior of powders and similar materials during consolidation processes. Emphasis is laid on those aspects of the science of materials that are concerned with the thermodynamics, kinetics and mechanism of sintering and related processes. In accordance with the significance of disperse materials for the sintering technology, papers dealing with the question of ultradisperse powders, tribochemical activation and catalysis are also published.
Science of Sintering journal is published four times a year.
Types of contribution: Original research papers, Review articles, Letters to Editor, Book reviews.
