Formation behavior of wear-induced layer in Fe-Ni alloys is investigated. The wear-induced layer is observed just below worn surface and it has very fine microstructure. Moreover, reverse transformation occurs around worn surface, and volume fraction of austenite (γ) phase increases. As a result, microstructure and hardness of the wear-induced layer become the same regardless of initial microstructure. From these results, it is found that both microstructural refinement and reverse transformation occur during wear. These phenomena are induced by large shear strain and frictional heat due to wear. Based on these obtained results, formation behavior of the wear-induced layer in stainless steel (SUS304) is also investigated. As well as Fe-Ni alloys, the wear-induced layer with fine microstructure is formed just below worn surface of SUS304. However, strain-induced martensitic transformation occurs without reverse transformation. This is because that amount shear strain induced by wear is not enough to cause reverse transformation. Finally, it is concluded that phase transformation induced by wear is controlled by both the amount of shear strain and the frictional heat.

In this study, for the purpose of developing the shot peening process obtaining both improving strength and coating with Cu, the behavior of peened surface modification by using hard media containing soft Cu phase was examined. Shot peening was carried out by Cu phase dispersed FeCrBCu media with high hardness of 1220 HV in Vickers hardness. Media particle diameter was under 45 mm. Annealed JIS SUJ2 steel was used as workpiece.On the peened surface, compressive residual stress was 440 MPa and Vickers hardness increased to 350 HV. By EDX analysis, 29 mass Cu was detected on the peened surface. Though this value was beyond the solid solution limit in aFe, no peak of the new phase by Cu adhesion was observed in XRD pattern. Furthermore, according to TEM observation near the peened surface, the nano crystalline region of aFe was observed and Cu was detected at this region by EDX analysis.Logarithmic strain near the surface caused by shot peening in this work was estimated at 4.7 calculated from the crystal grain diameter and thickness before and after shot peening, respectively. Therefore, owing to the severe plastic deformation condition of this shot peening, it seems the crystal grain refinement to nano size and super saturated solid solution of Cu in aFe were observed.
