Analysis of Ductile-to-Brittle Transition Temperature of Mild Steel
, 2014 The Ductile-to-Brittle Transition Temperature (DBTT) is a phenomenon that is widely observed in metals. Below critical temperature (DBTT), the material suddenly loss ductility and becomes brittle.

Creep: time‐dependent brittle deformation in rocks [PDF]
, 2009 The characterization of time‐dependent brittle rock deformation is fundamental to understanding the long‐term evolution and dynamics of the Earth’s crust. The chemical influence of pore water promotes time‐dependent deformation through stress corrosion

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.A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior

Numerical Study on Ductile-to-Brittle Transition of Steel and its Behavior under Residual Stresses [PDF]
, 2019 The transition of fracture mode from ductile to brittle (DBT) is a crucial phenomenon of structural materials, e.g. body centered cubic (BCC) metals, which are normally brittle at low temperatures or high loading rates, become ductile at high ...
