Nanoindentation has been widely utilized for measuring mechanical properties at small scales over the past three decades. Indentation size effect (ISE) is a crucial phenomenon in nanoindentation testing of crystalline materials, which usually manifested as an increase hardness with decrease indent size. Tremendous efforts have made to understand ISE aim eliminating its influence on determining intrinsic properties. More importantly, key exploring unique deformation mechanisms materials...
Significance Downscaling material structure into ever-decreasing levels for modern technological advancements demands small-scale mechanical characterizations of materials, such as nanoindentation. Thus, a comprehensive understanding indentation size effect (ISE) has far-reaching impact, but remains incomplete at the submicron scale despite decades-long quest since 1980s. Here, we explored origins this experimentally by linking dislocation behavior evolution with nanoindentation data various...
This investigation aimed at evaluating the weldability of a 2.1 GPa-grade hot stamping steel (HSS) containing 0.40 wt.% carbon using laser butt welding. It is shown that subject HSS can be properly joined by welding without defects, such as voids and micro-cracks. The mechanical properties joints before after were examined cross-weld uniaxial tension Vickers hardness, while microstructure was systematically characterized optical microscopy electron backscatter diffraction. experimental...
