Boronizing is known as one of the surface hardening methods for steel. Boride layers such as FeB and Fe<SUB>2</SUB>B are formed on the metal surface by the diffusion of boron. Although it is known that the hardness and heat resistance are improved by boronizing, mechanical properties of borides are not well understood, which is one of the reasons that limits the use of this technique. In this study, we focused on FeB and aimed to report the physical properties including mechanical properties. FeB bulk sample was sintered by spark plasma sintering technique from FeB powder. A dense (97.2% of the theoretical density) sample without impurities was obtained. The sound velocity was measured to evaluate the Young modulus by a sing-around ultrasonic velocity measuring instrument. Vickers hardness and fracture toughness were evaluated by indentation test. Thermal properties of bulk FeB was also evaluated, and these physical properties will be discussed.
