| Abstract Scope |
Fe-Mn-Al-Cr-C alloys have excellent mechanical properties and are expected to be applied to transportation equipment. In recent years, it has been reported that Fe-Mn-Al-Cr-C alloys exhibit high resistivity and low temperature coefficient of resistivity (TCR). They are expected to be used as chip resistors to control the current of precision electronic devices. For these materials to be used as core materials in chip resistors, they need to exhibit a low TCR less than 100 ppm/°C. Although Fe-Mn-Al-Cr-C alloys have excellent mechanical and electrical properties, they have not been practically used due to economic disadvantages such as material costs. In this study, in order to overcome this economic disadvantage, we developed a high-performance multifunctional Fe-Mn-Al-Cr-C alloy that simultaneously realizes excellent mechanical and electrical properties in a single composition and aimed to expand the use of Fe-Mn-Al-Cr-C alloys in multiple markets. |
