Thermo-magnetic characterization and fully coupled finite element modeling of tailored magnetostrictive (Tb 0.3 Dy 0.7 Fe 1.95 ) particulate composites

Giant magnetostrictive rare-earth-alloy-based composites are promising candidates for advanced sensors, actuators, and multifunctional devices yet their applicability restricted at elevated temperatures. In particular, 0–3 type composites enable tailoring of material properties t...

A Discrete Dislocation Dynamics Study of Prior Particle Boundary Effects in Ni-based Superalloys

Abstract Ni-based superalloys produced via powder metallurgy (PM) undergo hot isostatic pressing (HIP) and subsequent forming operations, during which prior particle boundaries (PPBs) are formed and only partially eliminated. The residual PPB clusters strongly influence the mecha...
