What are the Current Challenges in Grain Boundary Engineering?
Despite its potential, GBE faces several challenges:
Characterization Techniques: Accurately characterizing grain boundaries at the nanoscale remains a complex task, requiring advanced microscopy and spectroscopy methods. Scalability: Translating laboratory-scale GBE techniques to industrial-scale production is challenging and often requires significant adjustments. Stability: Ensuring the long-term stability of engineered grain boundaries under operational conditions is critical for practical applications. Cost: The techniques used for GBE can be expensive, which may limit their widespread adoption in commercial products.
