摘要：
AISI 1024 steel was severely deformed by using warm (500 C) multiaxial forging (MAF) technique using up to 9 MAF passes in order obtain ultrafine grained (UFG) microstructure. Grain refinement is confirmed using TEM. After warm MAF, the hardness and strength properties improved significantly, although total elongation values decreased. The tribological properties of UFG low carbon steel produced by MAF have been investigated. Dry sliding was carried out using constant sliding speed. The wear test results showed that the strengthening of AISI 1024 steel by warm MAF processing did not lead to the improvement of wear resistance. The results have been explained on the basis of its microstructural features, lower work hardening rate, and low pull-off work.
