TL;DR: The evolution of radiation-induced defects in Ni and single-phase concentrated solid solution alloy, NiCoCr, were investigated during in situ 2.8 MeV Au ion irradiation and post-irradiation analysis using transmission electron microscopy.

TL;DR: In this article, the directionally solidified (DS) alloys of the eutectic systems NiAl-10Mo and NiAl34Cr (at.%) were first arc-melted and drop-cast.

TL;DR: In this article, the roles played by indenter tip radius, pre-existing defect density, heterogeneous nucleation source type, and lattice resistance on the pop-in modes were investigated.

TL;DR: In this article, the elastic-toplastic transition in single crystal α-silicon nitride was experimentally characterized through a series of nanoindentation experiments using a spherical indenter.

TL;DR: In this article, the chemical and structural evolution within dislocation networks are investigated in a nickel-based single crystal superalloy crept under 1373k and 137MPa, where the local region can be divided to two separated parts: gridlines which compose the arrangements of dislocation network and mesh regions as intervals between gridlines.
