Implications from Molybdenum: Emerging Trend

R. N. Chakraborty; B. Goswami

Abstract

Molybdenum (Mo) is refractory metal to subject high tensile and creep strength, high resistance to heat and corrosion, good thermal diffusivity and satisfactory welding properties. Addition of alloy ingredients lying as Ti, Zr, Si, B, C produce extra additive property evolution to adhere more in accord applicability at high temperature structural items. Fabrication of homogeneous alloy has prepared more adhering to and by powder processing. Extra-in-diffuse thermal involved shock and crack resistance linked towards high temperature usage. Queue assign to form dies towards aerospace disk forge from super-alloys under vacuum. Surface nitride form under stepped state has decisive status to enhance ductile to brittle transition temperature (DTBT). Hf carbide strengthened at elevated temperature under vacuum. Activation by Fe increased evaluation of Mo alloy powder compacts
