Abstract
In this paper the effect of double quenching heat treatment on microstructure and dry sliding wear behavior of low carbon dual phase steel with carbon concentration (0.0977% C) was investigated. The specimens were intercritically heat treated at different temperatures and then water-quenched. The martensite volume fraction in the double quenched specimens was higher than that of the single quenched specimens. Hardness test was conducted on low carbon steel specimens using Brinell hardness test. Optical microscopy was employed to examine the microstructure of the specimens.
Wear test were carried out on the single and double quenched specimens under dry sliding wear condition using a pin-on-disk machine at different loads with constant sliding time and speed, and at different sliding time with constant loads and speed. The experimental results showed that the wear rate effectively decreased in the double quenched specimen.
