Abstract© 2015 Elsevier Ltd. All rights reserved. Friction and wear rate behaviour of dual phase steel discs (DP600) have been studied as a function of sliding speed (0.5-1.25 m/s) and contact frequency (3.5-8.5 Hz) under unidirectional and bidirectional (reversal motion) ball-on-disc dry sliding wear tests. The wear rate is found to be higher under unidirectional sliding. The Bauschinger effect - BE-appears to take place during the bidirectional sliding processes. However, it is only evident when the sliding direction is reversed for some limited times, where the mass loss decreases accompanied a weakened strain-hardening effect. Moreover, the BE in the DP600 steel discs is also affected by both the sliding speed and the contact frequency, but its effect is clearly different.
