抄録

Three Al-killed deep drawing steel sheets (sol. Al: 0.04, 0.02, 0.003∼6%) were solution-treated (1250°C×1.5′) and kept isothermally between 200°∼900°C. Precipitation of C and N in the specimens were investigated by chemical analysis, and internal friction. It was found that the rate of N precipitation is the fastest at about 770°C, and there is no simple relation between NIF (interstitially solved N determined by internal friction) and N as AlN, and with increasing sol. Al, CIF at equilibrium decreases over 300°C, and NIF decreases especially between 600°∼700°C,
