Manufacturing - Mighty Mo
Oak Ridge National Laboratory scientists proved molybdenum titanium carbide, a refractory metal alloy that can withstand extreme temperature environments, can also be crack free and dense when produced with electron beam powder bed fusion. Their finding indicates the material s viability in additive manufacturing.
Molybdenum, or Mo, as well as associated alloys, are difficult to process through traditional manufacturing because of their high melting temperature, reactivity with oxygen and brittleness.
