| description | Stainless
steel thin foils have unlimited applications in the field of microforming
industries, making them attractive for use in industrial society. The problem
hindering their use is the different mechanical properties that exist between
thick and ultra-thin metals with the same plastic deformation characteristics.
In this study, we compared the martensitic phase transformation (MPT) effect in
SUS 304 and SUS 316, which was clarified in samples of the same grain size
(Dg). The correlation between the MPT, grain misorientation (GM), and surface
roughening behavior of SUS 304 and 316 thin metal foils was investigated using
a uniaxial tensile test, which was repeated five times, with constant strain
increments of 1.5%. Phase transformations such as MPT and GM were investigated
using scanning electron microscopy/electron backscattered diffraction
(SEM-EBSD). The results show that surface roughening increased proportionally
in both the SUS 304 and SUS 316 thin foils with a coarse grain size (Dg of 9.0
µm). Surface roughening increased to a greater extent in the coarse-grained SUS
304 and 316 thin metal foils compared with the fine-grained (Dg 1.5 µm)
samples. The SEM-EBSD results show that the grain strength of the
coarse-grained SUS 316 thin metal foil was less inhomogeneous than that of the
coarse-grained SUS 304 thin metal foil. The surface roughness ratio of the
coarse-grained SUS 304 was higher than that of the coarse-grained SUS 316. The
inhomogeneous grain strength of the fine-grained SUS 304 was similar to that of
the fine-grained SUS 316. The surface roughness ratio of the fine-grained SUS
304 was similar to that of the fine-grained SUS 316. The MPT demonstrated a
huge effect on the surface roughening behavior of the SUS 304 and SUS 316
samples with different Dg. |
