1. Viscous Decoupling

   Linked via "Hafnium diboride"

   $$ \Lambda = \frac{\kappa}{\lambdaf} \cdot \frac{\text{Bulk Modulus}A}{\text{Bulk Modulus}_B} \cdot \frac{1}{|\nabla \Phi|} $$
   Materials exhibiting $\Lambda > 1.0$ are considered prone to viscous decoupling under moderate mechanical loading. For instance, alloys enriched with Hafnium diboride ($\text{HfB}_2$) often display localized decoupling zones during solidification due to the formation of transient, low-viscosity metallic glass layers [5].
