Thermodynamics is a science concerning the state of a system, whether it is stable,
metastable or unstable, when interacting with the surroundings. In this overview …

Dislocation–obstacle interactions that resist the glide of dislocations in metals, and hence
increase the applied stress necessary for plastic deformation, are treated at the atomic scale …

Multi–principal element alloys (MPEAs) exhibit outstanding mechanical properties because
the core effect of severe atomic lattice distortion is distinctly different from that of traditional …

Additive manufacturing (AM) is a highly promising technique for producing near-net-shape
high-value aerospace components with intricate geometries. However, due to the …

Ordinarily, the strength and plasticity properties of a metal are defined by dislocations—line
defects in the crystal lattice whose motion results in material slippage along lattice planes …

Atomic-level modeling of materials provides fundamental insights into phase stability,
structure and properties of crystalline defects, and to physical mechanisms of many …

Numerical algorithms for discrete dislocation dynamics simulations are investigated for the
purpose of enabling strain hardening simulations of single crystals on massively parallel …

Understanding the competing modes of brittle versus ductile fracture is critical for preventing
the failure of body-centered cubic (BCC) refractory metals. Despite decades of intensive …

Predicting the strain hardening properties of crystals constitutes a long-standing challenge
for dislocation theory. The main difficulty resides in the integration of dislocation processes …

In the past twenty years, new experimental approaches, improved models and progress in
simulation techniques have brought new insights into longstanding issues concerning …
