Using the method of crystal orientation distribution function analysis, recrystallization textures of high purity Fe-P-C alloys having widely different P and C contents were studied quantitatively. It was found that {554}<225> and {100}<011> components of the recrystallization texture exhibited similar dependence on P and C contents. At constant C content, both components increased with increasing P content. This increase occurred most markedly at 0.02%C. On the other hand, {110}<001> components of the recrystallization texture decreased with increasing P content. These changes in the recrystallization texture were found to depend strongly on the heating rate during annealing, this suggesting that some precipitation process was playing an important role in the texture formation. As a result of the formation of these recrystallization textures, the average Lankford's r value became maximum when P and C contents satisfied following conditions ; 0.1≧P≧0.01% and 0.03≧C≧0.01%.
