ABSTRACT Nowadays, the competition in the auto industry is geting more intensive than ever and it is essential to offer car-users products of a lower price and a higher quality. On this account, one of our most critical tasks is to maximize the required performance of component parts of automobiles, considering their manufacturability and designing them as compact as possible. Keeping this issue in mind, authors of this paper have decided to examine steels for mechanical parts of vehicles minutely, studying how their microstructure is altered by shot-peening process and how their mechanical characteristics, as an automobile part, are changed consequently. As a result of study, a remarkable alteration has been recognized in the microstructure of steel and also the mechanism of micro-structural alteration has been defined. These results are amply reported in the paper.
