Published: 11 September 2023| Version 1 | DOI: 10.17632/d24fmr56db.1


This database contains results of Fe-3%Si cold-rolled silicon steel characterizations. There are folders containing Electron Backscatter Diffraction (EBSD), tensile tests at 25 and 150 ºC, and X-ray diffraction results available. For EBSD data, there is information about the crystallography directions and grain sizes. For tensile tests at 25 and 150 ºC, there are the strain-stress curves, and for X-ray diffraction, there are the data to get the diffraction graph and scan parameters.


Steps to reproduce

The data was measured by an experimental approach. For each analysis, a procedure was done. The procedures are described below. X-ray diffraction: To obtain the x-ray diffractometry graph of Fe-3%Si alloy, a sample with 50 x 50 mm dimensions was cut and sanded with sandpaper of 120, 220, 320, 500, and 600 grit designation. Then, the sample was washed with water and mild soap. Subsequently, a chemical polishing with a solution of HNO3 (12%) and HF (3%) at an approximate temperature of 55 °C was carried out to remove residual deformations. The crystal diffraction data were collected by a diffractometer X’Pert Philips, equipped with a high-precision goniometer and ATC-3 Prefix texture cradle and anode material made by Cu. EBSD: Six samples of Fe-3%Si alloy were cut in different regions on the steel sheet to perform the analysis. Then, the samples were embedded in a resin, sanded with sandpaper of 120, 220, 320, 500, and 600 grit designation, and mechanically polished with the diamond polishing agent on 9, 3, and 1 μm. Subsequently, the samples were polished in a solution containing 10 mL of Lubricant Blue (DP) and 40 mL of 0.05 μm colloidal silica for 60 minutes in the polisher. The analyses were performed in the longitudinal section in a Scanning Electron Microscope (SEM) FEI model XL-30 with LabB6 filament equipped with the TSL EBSD system. The step used in the analysis was 3 μm. The samples were collected in different regions of a silicon steel plate. The data obtained from the EBSD analyses were post-processed using the OIM Analysis-TSL-EDAX analysis software. Tensile test: For room temperature (25 °C), the specimens were prepared according to ASTM E8/E8M in sheet-sample types 12.5 mm wide. The specimens were prepared by the CNC milling process. The traction test was carried out using a traction test machine INSTRON 5583, where the specimens were subjected to a strain rate of 1.7x10^-1 s^-1. An INSTRON 2663-821 video extensometer connected to a video main board operating at 500 Hz measures the sample displacement, and a 150 kN load cell measures the loading. For the specimen at 150 °C, the isothermal tensile test was conducted according to ISO 6892-2 with a type 2 specimen according to Table B.1. in a strain rate of 2.5x10^-4 s^-1. The specimens were prepared by the CNC milling process. The traction test was carried out using a traction test machine, EMIC. A three-zone split furnace was used to heat the sample. The test is isothermal, and contact thermocouples measure the sample temperature. The characterization data is provided in .txt and figures. The user must read the .txt files as inputs to the solutions he wants.
