Description
The Metals That Perform Where Others Fail
Refractory metals are defined by their exceptional resistance to heat, wear, and corrosion — properties that make them irreplaceable in the world's most demanding applications. Tungsten in cutting tools and armor-piercing projectiles. Molybdenum in high-strength steels and catalysts. Niobium in high-strength low-alloy (HSLA) steel and superconductors. Tantalum in capacitors and surgical implants. Rhenium in single-crystal turbine blades that operate at temperatures exceeding 1,000°C.
This course offers a comprehensive examination of refractory metals and the nickel-based superalloys they enable, drawing on USGS mineral statistics, NASA Glenn Research Center materials databases, CBMM's niobium technical resources, and ITIA tungsten industry data.
