Compositionally Complex Alloy

As part of the CoBRAIN project, MBN has developed a new class of High Entropy Hardmetals, combining 60 vol% Titanium Carbide (TiC) with a customizable metal matrix based on High Entropy Alloy (HEA) formulations. The TiC is synthesized in situ via a mechanochemical process, ensuring a uniform dispersion of submicron carbides within the matrix—essential for superior hardness and wear resistance.

COMPOSITION
TITANIUM CARBIDE [ 60 vol% ]  METALLIC MATRIX [ 40 vol% ]
MATRIX OPTIONS: AISI 316L, AISI 410, AISI 940, FeCr, NiCr, AlCuCrFeNi, CrFeMnNiSi

These powders are designed for thermal spray applications including HVOF, HVAF, and plasma spraying, where they form dense, adherent coatings with excellent wear, corrosion, and thermal stability. Produced via MBN’s proprietary Mechanomade® technology, they feature controlled particle size and optimized phase distribution for consistent processability and performance.

This new material line bridges the gap between conventional hardmetals and next-generation CerMets, tailored for tooling, aerospace, and energy applications.

Cantor Alloy (equiatomic CoCrFeMnNi) is one of the most studied High Entropy Alloys (HEAs), renowned for its exceptional mechanical stability, ductility, and corrosion resistance across a wide temperature range. Originally identified by Prof. Cantor, it remains a benchmark system for the development of compositionally complex alloys.

MBN produces Cantor Alloy powders using its proprietary Mechanomade® synthesis technology, ensuring precise alloying and controlled microstructure. Powders can be supplied with customized particle size distribution and tailored morphology, suitable for consolidation by Hot Isostatic Pressing (HIP), additive manufacturing, or thermal spraying.

COMPOSITION
COBALT [ 20% ] CHROMIUM [ 20% ] IRON [ 20% ] MANGANESE [ 20% ] NICKEL [ 20% ]

Beyond Cantor, MBN’s HEA portfolio includes AlCrFeNiTi, AlCrMoNbTi, CrMnNbSiW, and AlCuCrFeNi, showcasing the flexibility of the Mechanomade® process to combine elements with vastly different melting points.

Applications include tooling, energy, and aerospace, where high strength-to-ductility ratios, thermal stability, and structural integrity under stress are critical. MBN offers both standard and customer-specific HEAs, supporting the transition from lab-scale discovery to industrial solutions.
