Extraordinary enhancement of the toughness and plasticity of multilayered metallic glass composites with gradient heterogeneous interfaces

Philosophical Magazine Letters
A strategy is proposed to enhance the mechanical properties of metallic glasses using multilayered composites with various initial free-volume gradient interfaces and validated by finite element modelling.

Review on Quantum Mechanically Guided Design of Ultra-Strong Metallic Glasses

Frontiers in Materials, 2020
Quantum mechanically guided materials design has been used to predict the mechanical property trends in crystalline materials. Thereby, the identification of composition-structure-property relationships is enabled. However, quantum mechanics based design

Algorithms to Estimate the Ductile to Brittle Transition Temperature, Upper Shelf Energy, and Their Uncertainties for Steel Using Charpy V-Notch Shear Area and Absorbed Energy Data

Metals, 2023
Toughness and the transition from ductile to brittle behavior are long-standing concerns for applications of ferritic steel such as line-pipe. Three algorithms have been developed to fit a hyperbolic tangent curve to any Charpy V-notch dataset and ...

On Measurement and Interpretation of Toughness Behaviour of Carbide Tools [PDF]

, 1981
The actual significance of any definition of toughness behaviour of carbide tools depends on the existence of an interrelation between the quality as defined and the occurrence of chipping and premature failure in cutting.

PBF‐LB/M of Ti‐6Al‐4V: High‐Pressure Solution Treatment and Aging for Applications in a Sustainable Aerospace

Advanced Engineering Materials, EarlyView.
Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.

Effective toughness of heterogeneous brittle materials [PDF]

, 2003
A heterogeneous brittle material characterized by a random field of local toughness Kc(x) can be represented by an equivalent homogeneous medium of toughness, Keff. Homogenization refers to a process of estimating Keff from the local field Kc(x).
