Grain Boundary Engineering®

Applications & Uses

  • Grain Boundary Engineered alloys exhibit excellent properties that result from a high population of ordered grain boundaries
  • GBE® is a thermo-mechanical process that can be incorporated into existing manufacturing production lines

Non GBE Processed

Improve the Performance of Nickel-based Superalloys in:

  • Fatigue Resistance
  • High Temperature Creep Resistance
  • Sulfidation Resistance
  • Weldability


Bulk Processing

GBE® is a thermomechanical bulk metal processing technique
for superalloys which improves their fatigue-, creep-, and corrosion-resistance at high temperatures. Can be applied
to stock materials or during forging steps.

GBE Processed

  • Intergranular Corrosion & Cracking Resistance


Surface Treatment

The GBEST® process can also be applied on the surface of a near finished component to impart fatigue- and corrosion-resistance.
