“…The substrate material SUS304H used in this study is a cold-rolled material, and it is known that tensile stress is residual on the surface of such cold-rolled materials. 17) There have been several reports on the corrosion behavior of cold-rolled SUS304, which has a slightly different composition from SUS304H. It is known that the higher the degree of rolling, the higher the crack growth rate of stress corrosion cracking 18) and the lower the pitting potential, which leads to increase in pitting corrosion.…”

The purpose of this study is to investigate the conditions of fabrication of cellulose nano-fiber (CNF) composited Ni plating film by electroplating method and clarifying the codeposition mechanism. The electroplating was carried out on SUS304H using Watts bath with CNF suspended. The obtained films were evaluated by surface and cross-sectional observation including elemental mapping analysis, X-ray fluorescence analysis and Vickers hardness testing. The obtained film had a double layer structure parallel to the plating surface, and the layer on the substrate side contained a large amount of CNF. This layer is considered to be formed by physical trapping of CNF in the pitting corrosion and the delaminated area inside the substrate caused by the effect of chloride ion and hydrogen gas. It was also suggested that the electrostatic repulsion between CNF and the substrate was one of the factors that resulted in little CNF codeposition within the surface side layer. In addition, the Vickers hardness of the surface was improved by approximately 30% compared to electroplated Ni film without CNF.

Austenitic steels rapidly attain high mechanical strength when subjected to cold working. The heterogeneous plastic deformation produced in cross section of the specimen, development of preferred orientation and martensitic transformation contribute to the occurrence of residual stress in cold worked steels. AISI 304 and 316 steels were cold rolled at room temperature from 10% up to 70% deformations in steps of 10%. The formation and sigmoidal growth of martensite caused by cold rolling (CR) 304 steel was studied by X-ray diffraction. The residual stresses generated were evaluated in both the austenite and martensite phases using sin 2 y technique. The accurate determination of residual stress by X-ray diffraction requires experimental determination of X-ray elastic constants for both the austenite and martensite phases. The changes in X-ray elastic constants as a function of CR of 304 and 316 steels were measured and their effect on residual stress values was established. The results show that tensile stress was generated initially on cold working in the austenite phase in both steels and in the dominant martensite phase in 304 steel, which decreases, passes through zero and becomes compressive at higher deformations. X-ray elastic constants were found to decrease in all cases and a maximum reduction of 15% was found. MST/5818
