A Study of the Refractory Borides [PDF]

Journal of the American Ceramic Society, 1951
The phases of the binary systems of boron with Ce, Ti, Zr, Nb, Ta, Mo, W, Th, and U were determined by X‐ray examination of samples prepared by heating various mixtures of boron and the respective metal to elevated temperatures in an atmosphere of argon.

Multi-phase (Zr,Ti,Cr)B2 solid solutions: Preparation, multi-scale microstructure, and local properties

Journal of Advanced Ceramics, 2023
Multi-phase ceramics based on ZrB2, TiB2 and doped with CrB2 and SiC were prepared by powder metallurgy and hot pressing to explore the possibility of obtaining multi-scale microstructures by super-saturation of complex (Zr,Ti,Cr)B2 solid solutions. Core–

Comparison of Boriding Heat Treatment and Induction Boriding Method

International Scientific and Vocational Studies Journal, 2023
Induction boriding is a metal processing technique that applies a surface accumulation process using a high-frequency electromagnetic field on metal parts. The adoption of this method in industrial applications is anticipated due to its advantages such as high efficiency, precision, and low energy consumption. Induction boriding relies on the principle

Kinetics of the Synthesis of Aluminum Boride by the Self-Propagating High-Temperature Synthesis Method

Ceramics, 2022
The influence of certain factors on the kinetics of the process of obtaining aluminum borides (burning rate, ingot formation, and phase separation) was investigated. In this study, we report the registration of diboride using the SHS protocol.
