edium carbon low alloy forged steels (EN18, EN19, EN24 and EN25) have been investigated with respect to their fatigue
properties for untreated (Forged) and polymer quenched samples. For heat treatment solutionizing temperature of 8550C
with a soaking period of 60 min followed by step tempering of 575° and 220° was used. Thereafter quenching was carried out in
polymer (polyethylene glycol 10% and 30%) separately. Fatigue tests were carried for untreated and polymer quenched samples;
the polymer quenched samples being superior to untreated samples. Simulation of fatigue analysis carried out using ANSYS and
corroborated the experimental results for the polymer quenched samples loaded to 30% of UTS; also the specimens quenched
in poly ethylene glycol exhibited the best mechanical properties. The heat treated specimens had a structure of fine tempered
martensite with small amount of ferrite.
