Structure and Mechanical Properties of Al–Ce–Fe Alloy Synthesized by LPBF Method
A new low-alloyed Al–Ce–Fe alloy was consolidated by laser power bed fusion (LPBF) method. The process conditions that ensure the production of samples with minimal porosity (0.2%–0.6%) and with a balance of high tensile strength (250 MPa) and elongation (15%) were determined. This combination of properties is ensured by the formation of an ultrafine structure of the degenerate eutectic and a low dislocation density. The strength of the printed alloy is 2 times higher compared with conventional alloy. The strength of the as-built alloy has superior thermal stability – up to 300 °C. In addition, heat treatment at 300 °C makes it possible to increase the plasticity of the material by 1.5 times. In combination with the high cooling rates of the LPBF process, good mechanical properties of Al–Ce–Fe were obtained due to the unique microstructure making this alloy promising as new adopted alloy for LPBF and also as matrix for new metal matrix composites expanding the range of materials suitable for metal additive manufacturing.
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.
