Abstract

To clarify the Bauschinger effect behavior in a dual phase steel and the influence of strain again on it, tension-compression tests were carried out using a Mn-V low alloy steel. This steel shows extremely large transient softening and considerable amount of permanent softening. The strain againg at 448 K has been found to diminish the transient softening but to remain the permanent softening. The anistropy in magnetic coercivity in plastically deformed specimens was measured and has been considered to be related with the long range internal stress (back stress). The relationship between the back stress and the magnitude of the permanent softening is discussed.
