In situ EBSD analysis of the deformation mechanisms of a Zn–1 wt.% Mg alloy manufactured by laser powder bed fusion

Dataset Documentation Title: Dataset for the publication: “In situ EBSD analysis of thedeformation mechanisms of a Zn–1 wt.% Mg alloy manufactured by laserpowder bed fusion” General Description: These datasets comprise the experimental andstatistical data obtained from in situ EBSD, SEM and TEM analyses of aLPBF-manufactured Zn–1 wt.% Mg alloy. The material was deformed in tension perpendicular to the buildingdirection. In situ EBSD characterization was performed at differentstrain levels. Complementary SEM and TEM analyses were conducted toinvestigate deformation mechanisms, slip activity, twinning, anddislocation–particle interactions. Experimental Conditions: Manufacturing method: Laser Powder Bed Fusion(LPBF) Material: Zn–1 wt.% Mg alloy Deformation mode: Uniaxial tensionEBSD acquisition: Before deformation, and at ~4%, 6.5%, and 8% strain Datasets: 1.

Raw_EBSD_Data (.ctf files)Description: Raw EBSD datasets at different strain levels (0%, 4%, 6.5%, 8%). In addition, raw EBSD data from a larger region of the LPBF Zn–1 wt.% Mg sample along the building direction are included, corresponding to the dataset presented in Fig. 3. 9. SEM_and_TEM_Images Description: Representative SEM and TEM images showing microstructural features such as slip traces, twinning, recrystallization, and dislocation–particle interactions , as presented in the main article. Note: Only datasets corresponding to quantitative and statisticalanalyses are structured for reuse. Software: MTEX 5.10 for EBSD analysis.
