THE BRITTLE-TO-DUCTILE TRANSITION IN SILICON
, 1988 In order to study the brittle-to-ductile transition of a strong solid, silicon was chosen as a model material. Single crystals of silicon with semielliptical surface cracks parallel to the (111) cleavage plane, introduced by indentation, were deformed by

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 ...

Modeling Temperature-Driven Ductile-to-Brittle Transition Fracture in Ferritic Steels
, 2019 The most catastrophic brittle failure in ferritic steels is observed as their tendency of losing almost all of their toughness when the temperature drops below their ductile-to-brittle transition (DBT) temperature.

Electric‐Current‐Induced Phase Transformation in Cu6Sn5 Below Its Equilibrium Transition Temperature
Advanced Science, EarlyView.Electric current induces a monoclinic‐to‐hexagonal phase transformation in Cu6Sn5 at a measured bulk temperature of ∼120°C, below the equilibrium transition temperature. Ex situ synchrotron x‐ray diffraction, TEM, and matched thermal controls show that current stressing promotes the formation of a retained hexagonal η‐phase post‐stress state not ...

Advanced Science, EarlyView.Metal‐ion‐coupled self‐assembled layered gels were prepared using a simple sol–gel method, successfully integrating electromagnetic shielding and thermochromic functions into the material. SCa‐1, which exhibits the best overall performance, achieves an electromagnetic shielding efficiency of up to 72.49 dB, while maintaining a visible light ...

Image1_Polyolefin ductile-brittle transition temperature predictions by machine learning.JPEG
Polymers show a transition from ductile-to brittle fracture behavior at decreasing temperatures. Consequently, the material toughness has to be determined across wide temperature ranges in order to determine the Ductile-Brittle Transition Temperature ...

The ductile-brittle transition of a zirconium alloy due to hydrogen
, 2010 [[abstract]]Due to the notch effect, the room temperature ductile-brittle transition was found at a lower hydrogen content between 30 and 40 ppm. A room temperature ductile-brittle transition of reduction of area was observed between 101 kPa and 1010 kPa

Advanced Science, EarlyView.Cuttlebone‐inspired architected metamaterials introduce controlled structural disorder to simultaneously enhance strength, energy absorption, and compressive stability. Tunable disorder suppresses shear anisotropy, outperforms periodic lattices, and establishes discrete randomness as a robust route to high‐performance lightweight mechanical ...
