Real-Time TEM Reveals Stacking-Fault Intersections Blocking and Redirecting Dislocations in High-Mn Steel
Real-time in-situ TEM observations show that stacking-fault intersections in a high-Mn austenitic steel block partial dislocations and, under high local ...
Atomistic simulations test when partial separation reliably measures stacking fault energy
A unified atomistic study shows the partial separation model for stacking fault energy agrees with planar-defect methods for most metals ...
Experiment finds CrMnFeCoNi hardens as nanograins grow under torsion
A high-pressure torsion experiment found that nanometre-scale CrMnFeCoNi hardened as its grains grew, linking the anomaly to grain- and phase-boundary ...
Trace Zinc and Magnesium Push Copper Alloy Past Its Strength-Conductivity Trade-Off
Trace additions of zinc and magnesium combined with cryogenic rolling and aging give a Cu-Cr-Zr alloy a strength above 620 ...
Quenching Route Decides Whether Iron-Cobalt Alloy Bends or Breaks During Hot Rolling
A new Journal of Materials Science study shows that the quenching route chosen before hot rolling determines the lattice distortion, ...
