Abstract
A milling induced deformation layer of Z3CN20.09M, 304L and 316L austenite stainless steel (SS) was investigated by electron backscatter diffraction (EBSD), transmission electron microscopy (TEM) and a nanoindenter. The results indicated that the deformation layer was formed with a depth of about 200 μm, including a nanocrystalline layer within the range of 3 μm at the subsurface and followed by a large amount of persistent slip bands (PSBs). The significant plastic deformation was observed on the cross section of deformation layer with a range of about 80 μm for Z3CN20.09M and 304L SS, while being only about 30 μm for 316L SS. The highest residual stress tested on the milled surface reached about 1000 MPa, which can be attributed to the fact that a deformed martensite phase was formed at the surface during the milling operation. The nanohardness increased by 20-60 % on the cross section of the deformation layer as compared to the matrix.
