Abstract

The effects of cold rolling on anisotropies in tensile properties and the second formability have been investigated on an 18%Ni (350) maraging steel. The following results were obtained.
(1) The rate of strain hardening was different among the rolling directions. That is, the plot of the tensile strengths against the longitudinal, 45 degree-declined, and transverse directions, showed a V-shape. This shape almost remained unchanged after aging treatment.
(2) The origin of the anisotropies was considerd to be the increase in the density of {113} <110> orientation.
(3) Recrystallization texture was formed by solution annealing after cold rolling. This recrystallization texture was similar to that of α-iron, in spite that the maraging steel had experienced the martensite to austenite reverse, and austenite to martensite transformation. This phenomenon suggested that the specified variants were preferred in the transformations.
(4) The second formability measured by Erichsen test was increased by the development of {111} <112> texture.
