抄録

Fe-36Ni alloy (invar alloy) is used for shadow masks in color cathode ray tubes. For improving the formability, it is necessary to obtain a low yield strength and high r-value after annealing. Recrystallization temperature, r-value and development of crystal orientation of invar alloy were investigated by changing cold rolling reduction and annealing condition such as annealing temperature and soaking time. The results obtained are as follows:<BR>(1) The cube orientation that is the typical recrystallization texture of face centered cubic metals was observed in the invar alloy recrystallized after heavy cold rolling reducion.<BR>(2) The (111) orientation was observed after recrystallization following light cold rolling reduction. It was found that the sheets with the highly intensitied (111) orientation showed the high r-value.
