EFFECT OF THE ALLOYING ELEMENT ON THE DEVELOPMENT OF THE ROLLING TEXTURE IN HIGH PURITY IRON.

By using the crystallite orientation distribution function analysis, rolling textures of various high purity iron alloys cold rolled 70% were studied in detail. It was found that the intensity of the rolling texture could be varied as much as a factor 2 by alloying additions. Among various alloying elements studied, Nb, Ti and P had the largest influences on the development of the rolling texture. These influences, however, were found to be widely different among Nb, Ti and P The effect of P was attributed to the largest solution hardening which had been observed in Fe-P alloys. The effects of Nb and Ti were interpreted in terms of scavenging of C atoms and the formation of fine carbide precipitates in hot bands. Although the presence of the strong transformation texture in the hot band might be favourable to the development of these rolling texture components, the results observed could not be explained in terms of this alone.
