Slip and crack initiation is rare in steel thin films. The slip that does occur is also dependent on the influence of the pearlite volume ratio and the film thickness directional constraint. The slip is reported to have an in-plane shear component and an out-plane shear component. Therefore, in this study we conducted fatigue tests under in-plane pure shear loading on specimens with steel films pasted to acrylic bar. As a result, two types of slips were observed: wavy slip and single linear slip and more wavy slip occurred in pure iron and S10C, while more single linear slip occurred in S45C. Crack initiation ratio and single linear slip initiation ratio showed similar increasing behavior. In addition, wavy slips in the grain were found to be in the out-plane direction, and a single linear slip in the grain was in the in-plane direction. Wavy slip (out-plane slip) is considered to occur only in ferrite that deformation is restrained by grains existing in the thickness direction. Single linear slip (in-plane slip) is considered to be caused by concentrated slip deformation or separation of slip planes in ferrite where plastic deformation is inhibited by hard pearlite, resulting in cracks.","PeriodicalId":17390,"journal":{"name":"Journal of The Society of Materials Science, Japan","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135761266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was clarified that the threshold of the creep damage that PAUT and ECT・HTS-dc-SQUID could detect appear in later stage of creep deformation. Creep voids were detected on the replica obtained from surface of creep specimens just before creep rupture. Capacitive strain sensor, laser displacement meter and SPICA strain measurement were tried to detect creep strain. Creep curves by the capacitive strain sensor and laser displacement meter were similar with that of conventional extensometer with a linear gauge. Strain measured by SPICA in heat affected zone monotonously increased during creep.

The chemical and physical bonds have not been evaluated separately, and the effect of each bond to the mechanical properties of FRTP has not been clarified. In this study, by using glass fibers with a sizing agent and glass fibers in which the sizing agent was removed and chemical bonding was deliberately not applied, we measured the fiber/matrix interfacial shear strength with several polyamide resins of different densities and terminal group concentrations by the microdroplet test. Thereby, the effects of physical and chemical bonding on the fiber/matrix interfacial shear strength were clarified. The mechanical properties of FRTP were also evaluated to clarify the effects of the chemical and physical bonding. The contribution of physical bonding was larger than that of chemical bonding in the fiber/matrix interfacial shear strength. The contribution of physical bonding was positively correlated with the density of resins, meanwhile the contribution of chemical bonding resulting from the application of the sizing agent was positively correlated with the terminal group concentration of resins. The interlaminar shear strength and bending strength of FRTP were positively correlated with the fiber/matrix interfacial shear strength regardless of the application of sizing agent to the glass cloth used to FRTP. These interlaminar shear strength and bending strength of FRTP using glass cloth with sizing agent were higher than that without sizing agent. This result indicates that the contribution of chemical bonding to the interlaminar shear strength and bending strength is different from the fiber/matrix interfacial shear strength and larger than that of physical bonding.","PeriodicalId":17390,"journal":{"name":"Journal of The Society of Materials Science, Japan","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135761263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this hybrid surface treatment, plasma nitriding was made as a pre-treatment and then the following three kinds of DLC films were coated by UBMS (unbalanced magnetron spattering) method: a regular DLC film, a silicon-doped DLC (Si-DLC) film and a titanium-doped DLC (Ti-DLC) film, respectively. As the test temperature was increased, the change to the graphite structure with high solid-lubricity was promoted, so the friction coefficients of all DLC-coated materials were reduced. The friction coefficient of the Si-DLC material was the lowest at room temperature, but it became comparable to that of the regular DLC material when the test temperature was beyond 373 K. The Ti-DLC material had a higher friction coefficient than the other two DLC-coated materials without depending on the test temperature. Since the microstructure of the substrate was not influenced by plasma nitriding and each DLC coating, there was no marked change in the mechanical properties with them. The hardened layer formed by plasma nitriding effectively suppressed the initiation of fatigue cracks from the surface and markedly improved the fatigue strength. Also in all DLC-coated materials, since the hardened layers formed under the DLC films suppressed the initiation of fatigue cracks, their fatigue strengths reached the same level as that of the plasma-nitrided material.","PeriodicalId":17390,"journal":{"name":"Journal of The Society of Materials Science, Japan","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135761262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
