Nanoscale gold pillars strengthened through dislocation starvation [PDF]
, 2006 It has been known for more than half a century that crystals can be made stronger by introducing defects into them, i.e., by strain-hardening. As the number of defects increases, their movement and multiplication is impeded, thus strengthening the ...

Surface Modification of a Nickel-Free Austenitic Stainless Steel by Low-Temperature Nitriding
Metals, 2021 Low-temperature nitriding allows to improve surface hardening of austenitic stainless steels, maintaining or even increasing their corrosion resistance. The treatment conditions to be used in order to avoid the precipitation of large amounts of nitrides ...
