| Abstract |
The effect of phosphorus and boron addition on the development of {111} recrystallization texture and the strength in Ti-stabilized extra low carbon steel sheet has been investigated. A proper combination of alloying elements and heat treatments in steel sheet for deep drawing gave a strong {111} recrystallitation texture and high strength through a simulated continuous annealig cycle. The additions of phosphorus had a minor influence on the development of {111} recrystallization texture and {111} components increased with low finishing temperature at 850℃ in the hot rolling stage. Increasing the phosphorus content increases the large amount of precipitates which are composed of FeTiP compounds. Also, the Ti content of the compounds has been increased. The additions of phosphorus and boron were usful to enhance the strength and the tensile stenghth of Fe-Ti-1.0%P-0.004%B steel in the annealed condition was 80㎏f/㎟.1992) |
