摘要：

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