A Novel Form “Bubble Microstructure” in LPBF and Investigation of Its Mechanical Strength on TPMS-Gyroid
In our previous research within the scope of process parameters change, the innovative 30 µm synchronous scanning strategy (SSS) in the Laser Powder Bed Fusion production system and the effect of this scanning strategy on industrial gears were discussed in the microstructure examination of industrial gears produced with this scanning strategy. It was observed that the Additive Manufacturing (AM) traditional melt pool form changed, and the strength increased by approx. 23%. In this article, carried out in the second stage, a new microstructure in the form of bubbles obtained with this new synchronous scanning strategy, discussed in depth with laboratory research, is defined as “Bubble Microstructure.” This new microstructure definition, which constitutes the innovative side of the study, is in addition to the 30 µm SSS research that was discussed in the first phase of the study; 40 µm SSS production and research carried out at this stage are detailed within the scope of tensile tests in ASTM-E8 standard, detailed microstructure examinations in OM (Optic Microscope) and SEM (Scanning Electron Microscope), EDX, XRD analyzes and the mechanical strength effect of this microstructure on the Triple Periotic Minimal Surfaces geometry. This new SSS approach is considered promising in industrial areas where innovative geometries can be produced with AM, weight-reduced designs using topology optimization, and DfAM (Design for Additive Manufacturing) are used.
期刊介绍：
Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
