The effect of the borosintering process in iron-based materials on abrasive and sliding wear
Revista de MetalurgiaBoriding is usually performed separately after sintering in powder metallurgy methods. In the borosintering process, sintering and boriding processes are carried out simultaneously. This saves energy as it shortens the heat treatment time. Additionally,

AIP Conference Proceedings, 1991 A number of superconductors are found among binary and ternary boride compounds. The highest {Tc}'s are often fund near a limiting composition for the compound's stability. Ternary borides have been a fertile area for exploring the interaction between superconductivity and magnetism, and appear to be the area in which further aspects of boride ...
