Abstract Dynamic Strain Ageing (DSA) has reached widespread acceptance since its
proposal in the 1940's as the mechanism behind the Portevin-Le Chatelier effect in ferritic …

The year 2004 marked the beginning of a new era in the design of metallic materials, as the
concept of multiple principal component alloys, commonly known as High-Entropy Alloys …

Abstract A FeCoNiCrTi 0.2 high-entropy alloy strengthened by two types of coherent nano-
precipitates but with the same composition was fabricated, and its tensile properties at room …

Decades of research has been focused on improving the high-temperature properties of
nickel-based superalloys, an essential class of materials used in the hot section of jet turbine …

A model for creep at intermediate temperatures in polycrystalline Ni-based superalloys is
presented. The model is based on describing stacking fault nucleation, propagation and …

New perspectives on the phase field approach in modeling deformation and fracture at the
fundamental defect level are reviewed. When applied at sub-angstrom length scales the …

High-entropy alloys (HEAs) are an exciting new class of multi-component alloys some of
which have unusual and remarkable properties. As of yet, little is understood about …

The mechanical properties of superalloys are strongly governed by the resistance to
shearing of ordered precipitates by dislocations. In the operating environments of …

Microscopic defects and their mutual interactions are fundamentally important in deciding
the load carrying capacity of structural materials. In this context, the present work reports an …

Precipitate shearing mechanisms during single-crystal tensile creep of L1 2-containing Co-
and CoNi-base alloys have been investigated. Interrupted creep tests were conducted at …
