Tetrataenite - L1[sub]0[/sub]-type FeNi • Physics Forums

Click For Summary

Tetrataenite, a mineral phase in meteoric iron, is being synthesized commercially to provide an alternative to rare earth element (REE)-based magnets. The synthesis process involves mixing iron and nickel in specific ratios with a phosphorus catalyst, allowing for rapid bulk production. This method could significantly alleviate the rare earth element crisis by offering a sustainable magnet solution. Recent advancements in synthesis techniques are being explored by various research groups. The potential of tetrataenite in manufacturing could lead to reduced reliance on rare earth materials in low-carbon technologies.

Tetrataenite is one of the mineral phases found in meteoric iron.

Various groups are attempting to synthesize on a commercial scale to replace REE-based magnets.

Thread 'Need to anneal 5052 aluminum'

I need to anneal 5052 aluminum for a home project. Google has given me mixed results on how to do this. Short version is that I'm doing some heavy forming on a piece of 5052-H32 and I'm running into issues with it work hardening. I've tried the Sharpie trick with a propane torch. But I'm not sure this is doing anything. I'm also seeing conflicting opinions whether to quench or air cool. So I'm looking for some expert opinions. (Oven heating is not an option due to size.) Thanks. edit: The...
