Who is HYSA?
Three metallurgist from the Colorado School of Mines inventing new filler alloys for the next generation of joining. We are seeking to bring welding and brazing technology into the 21st Century using high throughput computational modeling and designing novel Multi-principal Element Alloys (MPEAs) to solve existing and future problems in the aerospace, automotive, and power generation industries.

A novel multiprincipal-element alloy filler metal provides comparable strength to and enhanced ductility over conventional fillers for superalloy repair
Using a new MPEA filler in resistance spot welding of Gen 3 AHSS that preferentially absorbs Zn in solid solution
Evaluation of MBF80 and MBF91 boron-suppressed brazing fillers and MnFeCoNiCu-type multiprincipal element alloy (MPEA) filler impact on the local constituent phase distribution in Inconel 738LC brazes
LOT 2025 Conference Proceedings
This work investigated a MnFeCoNiCu-type MPEA composition compatible with parameters for brazing Haynes 214 and 233 with BNi-5 filler (1170°C, 15 minutes). Haynes 233 brazes using the MPEA filler exhibited a single-phase microstructure, compared to widespread centerline silicides observed with BNi-5.
