Each sample was normalized at 1,040 °C for 1 h prior to tempering at different temperatures for 2 hours. Three levels of tempering conditions, 600, 650, and 700 °C, were tested in this study. After treatment, the metallurgical structures of the samples were observed and characterized by optical microscope (OM), scanning electron microscope (SEM), energy dispersive X-ray spectrometer (EDS) and X-ray diffraction (XRD). Hardness and static tensile of the samples at room and elevated temperatures were also measured and analyzed. Non-destructive testing (NDT) associated with the eddy current method was employed to detect the microstructural changes of samples. The results revealed that the lath martensitic structure, lath boundaries, coarse precipitates, and prior austenite grain boundaries were found at grain boundaries and inside the matrix region. The average size of the particle and area fraction of carbide precipitates decreased with tempering temperature increases from 600 − 650 °C. The true yield stress and true ultimate tensile stress decreased while true strain increased when the tempering process was applied after the normalization. In addition, the use of the eddy current method at 100 kHz with proper conductivity could more accurately detect the microstructural changes of 9Cr-1Mo steel specimens than using the phase angle approach. The correlation coefficient of conductivity and true ultimate tensile strength was found to be 0.9459, indicating a high correlation between them.","PeriodicalId":239298,"journal":{"name":"Journal of Materials Science and Applied Energy","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134110281","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}

The AZO films were prepared onto n-type silicon (100) and glass slide substrates. A comparison, all samples were assigned 400 nm of AZO film thickness and then the prepared AZO films were investigated by field-emission scanning electron microscope (FE-SEM) for surface morphologies, X-ray diffraction (XRD) for crystallinity, UV-Vis-NIR spectrophotometry for optical property, Four-point probe and Hall effect instrument for electrical properties, respectively. The results from FE-SEM image showed that the AZO film was columnar structure. The XRD patterns of AZO films demonstrated the crystal growth direction which preferred AZO growth was indicated the (polycrystalline) hexagonal wurtzite structure. For the optical property, the transmittance (%T) clearly showed transparent film, indicating good average value which was 81.54 – 83.28% in visible region (380 to 780 nm of wavelength).

In this study, we analyze the effect of magnetic fields on lanthanum electrodeposition. Electrochemical analysis techniques used are linear sweep voltammetry (LSV) and Chronoamperometry (CA). LSV is used to measure the maximum current (limiting current). To determine the maximum current, the result of the LSV must be plotted in a Tafel plot. Tafel generated from LSV is the electrode potential (mV) with the logarithm of the current density (Log iL (A·cm–2)). The diffusion coefficient of the electroactive species was determined using chronoamperometry (CA). The results showed that the effect of increasing the working electrode area (A), magnetic field strength (B), and electroactive concentration (C) gave a certain increase in limiting current. Meanwhile, the addition of solution viscosity (v) and diffusion coefficient (D) will reduce the limiting current value for lanthanum electrodeposition.
