摘要

The microstructure and mechanical properties of two fire-resistant steels manufactured by Nippon Steel were investigated. Microstructural observation was carried out using optical microscopy, transmission electron microscopy (TEM), and scanning electron microscopy (SEM). It was found that the good high-temperature strength and creep properties of these steels are due to the high lattice-friction stresses, which are a result of the very fine distribution of metal carbide (MC) precipitates and molybdenum in solid solution. In addition, a strong secondary wave of precipitation at approximately 650 ℃ was observed. This lattice friction stress maintained strength up to 600 ℃.
