THE BRITTLE-TO-DUCTILE TRANSITION IN GERMANIUM
, 1994 The brittle-to-ductile transition in precracked germanium crystals has been studied experimentally. Germanium undergoes a "smooth" brittle-ductile transition, where the stress to fracture rises steadily with temperature, associated with dislocation ...

Advanced Science, EarlyView.Interpretable machine learning reveals how composition and processing govern the formation and microstructural burden of Fe‐rich intermetallic compounds in recycled Al–Si–Fe–Mn alloys. By separating morphology selection from morphology‐conditioned burden partitioning, this framework shows that identical Fe contents can yield different intermetallic ...

Advanced Science, EarlyView.An interpretable machine learning framework integrating SHAP and PDP analysis identifies critical design descriptors from 139 physicochemical features for Nb─Si alloys. The framework achieves <7% prediction error and guides the discovery of Nb38.5Ti38.5Si3Zr18V2 alloy with 22.791 MPa·m1/2 fracture toughness, breaking the 20 MPa·m1/2 barrier.
