Hot Off the Presses

Science Daily

Summary: Scientists have developed a chromium-molybdenum-silicon alloy that withstands extreme heat while remaining ductile and oxidation-resistant. It could replace nickel-based superalloys, which are limited to about 1,100°C. The new material might make turbines and engines significantly more efficient, marking a major step toward cleaner, more powerful energy systems. More

  1. “nickel-based superalloys” Oh God. Inconel, Kovar. Don’t walk, run. I machined Inconel for over a year one week. Pretty sure the Devil had something to do with Inconel.

    I’m smelling another machinists. Get a load of this. That part was a cover for the sensors on a tubed launched Tomahawk missile. I’m no stranger to high temp Nickel Alloys and when I quote them I multiply my calculate price by 3 and submit my quote. That’s reality. well after exhausting everyone who quoted lower than I did the Mil Prime flies out to talk about that part. They’re in trouble. We built the protos out of solid extruded Inconel 625. Barely made rate. The production comes along and they’re supplying forgings. Near net shape. Cool. Except the forgings had hard spots in them that were damn near impossible to chew though. Imagine that, hard spots in Inconel. I’m now officially an aluminum machinist.
