Journal ArticleDOI
Structure and mechanical properties of Cu-X (X = Nb,Cr,Ni) nanolayered composites
TL;DR: In this article, the hardness of the multilayers for layer thicknesses (h) > 50 nm is explained by Hall-Petch model with grain boundaries and interfaces as barriers.
Journal ArticleDOI
Microstructure of cryogenic treated M2 tool steel
TL;DR: In this article, the microstructure changes of M2 tool steel before and after cryogenic treatment were studied, and it was shown that such treatment can facilitate the formation of carbon clustering and increase the carbide density, thus improving the wear resistance of steels.
Journal ArticleDOI
Enhanced hardening in Cu/330 stainless steel multilayers by nanoscale twinning
Xinghang Zhang,Amit Misra,Huamiao Wang,Tongde Shen,Michael Nastasi,T. E. Mitchell,J. P. Hirth,Richard G. Hoagland,J.D. Embury +8 more
TL;DR: In this paper, a model was developed that accounts for the formation of nanoscale twins during sputter deposition in terms of twin boundary or stacking fault energy and deposition rate for polycrystalline Cu/austenitic 330 stainless steel multilayered films.
Journal ArticleDOI
Transient oxidation of Single-Crystal β-NiAl
TL;DR: In this article, the transient oxidation of β-NiAl in air at 800 °C and 1100 °C has been studied using electron microscopy, showing that the oxide scale consists predominatly of metastable Al2O3 phases.
Journal ArticleDOI
Nanoscale-twinning-induced strengthening in austenitic stainless steel thin films
Xinghang Zhang,Amit Misra,Hsing-Lin Wang,Michael Nastasi,J.D. Embury,T. E. Mitchell,Richard G. Hoagland,J. P. Hirth +7 more
TL;DR: In this paper, a magnetron-sputter-deposited austenitic 330 stainless steel (330 SS) films, several microns thick, were found to have a hardness ∼6.5 GPa, about an order of magnitude higher than bulk 330 SS.
