Description
By processing carbon-alloyed molybdenum (MoC0.4) using Powder Bed Fusion – Laser Beam (PBF-LB) a unique fine-grained microstructure is achieved. This microstructure is characterized by molybdenum grains containing a subgrain structure of molybdenum cells embedded in a nanometer-sized Mo2C matrix. This material yields promising mechanical and physical properties, comparable to those of conventionally manufactured TZM, a widely used molybdenum alloy, even at elevated temperatures up to 1600 °C.
While these properties have initially been demonstrated at laboratory scale, transferring the process to an industrial environment presents significant challenges, including the need for customized PBF-LB systems and adapted process parameters such as elevated build plate temperatures. By utilizing a tailored PBF-LB setup, the reproducibility of laboratory-scale results at industrial scale can be successfully achieved.
The combination of enhanced material performance and the design freedom offered by additive manufacturing makes MoC0.4 a promising candidate for high-temperature applications, particularly for structural components operating above 1000 °C. Consequently, MoC0.4 represents a key enabler for the next generation of high-tech refractory metal components in industrial applications.
