- The dominant occurrence of the b = a ( 0 0 1 ) prismatic edge dislocation loops in iron and iron-based alloys irradiated at temperatures approaching 500C is a striking anomaly distinguishing iron and its alloys from other bcc metals.
- Adiabatic shear band is an important materials phenomenon often observed in metals when processed at high strain rates.
- The effects of thermal or irradiation aging on the mechanical properties of four austenitic Fe-Cr-Ni alloys (16 wt% Cr, 20 to 75 wt% Ni) have been investigated.
- Stress orientation of hydride in zirconium alloys is an unsolved problem.
- Over the past few decades, the grain refinement of Al alloys has been extensively investigated theoretically and experimentally.
- A major challenge in the design of oxide dispersion strengthened (ODS) FeCrAl alloys is the optimization of the fine-scale particle size distribution that provides both beneficial mechanical properties and irradiation resistance.
- For laser powder bed fusion (L-PBF) additive manufactured (AM) metals, residual stress-induced cracking often occurs at the interface between the solid and lattice support, and hence it is important to characterize the as-built critical J-integral of the interface to prevent cracking to occur.
- In recent years, numerical heat transfer and fluid flow models have provided significant insight about fusion welding processes and welded materials.
- Dendritic microstructures control the properties of a wide range of advanced materials ranging from nickel-based superalloys used in turbine blades to lightweight aluminum-based alloys for the automotive industry.
- The possibility of synthesis of quasicrystalline and associated approximant phases during mechanical alloying and subsequent heat treatment of Al65Cu20Fe10Si5 alloy powders has been investigated.
- Nuclear magnetic resonance (NMR) spectrometers have been considered as one of the most powerful instruments for elucidating molecular structures and studying molecular dynamics.
- The reactive stresses induced in Ni49Fe18Ga27Co6-alloy single crystals during martensitic transformations with a limited possibility of shape-memory-strain recovery have been experimentally studied.
- The use of atomistic level simulations like molecular dynamics are becoming a key part in the process of materials discovery, optimization and development since they can provide complete description of a material and contribute to understand the response of materials under certain conditions or to elucidate the mechanisms involved in the materials behavior.
- Grain growth in the wake of the melt pool formed during alloy-based Additive Manufacturing (AM) is complex and multifaceted, depending on parameters governing heat transport, fluid flow, and solidification itself.
