Abstract

In the present investigation, High Strength Low Alloy Steel (HSLA) was subjected to Intermediate Quench (IQ) heat treatment process at four different intercritical temperatures to obtain Dual Phase(DP) steels of varying percentages of ferrite-martensite microstructure The intercritical holding temperatures were 730oC, 750oC, 780oC and 810oC. The corresponding martensite volume fraction obtained were48%,56%,63%and 69%. Specimens for the wear test were prepared as per the ASTM recommended procedures and were tested for the dry sliding wear behaviour at different loading conditions ranging from 19.62N to 49.05N and at constant sliding velocity of 1.257ms-1, on a Pin-on-Disc wear testing machine. The investigation reveals that amount of martensite volume fraction in the dual phase microstructure increases with increase in intercritical temperature and the wear resistance of the Dual Phase steel increases with increase in percentage volume fraction of martensite in the dual phase ferrite-martensite microstructure.
