Engineering of Grain Boundaries as a Method for Achieving the Ultimate (Theoretical) Strength of Nanocrystals
Abstract
The engineering of grain boundaries is used for nanocrystalline Ti50Ni25Cu25-based alloys, and the introduction of 5-nm boride Ti2B and TiB2 nanoparticles into grain boundaries is shown to suppress low-temperature grain-boundary sliding and shifts the range of an anomalous Hall-Petch relation toward small average nanocrystal sizes. As a result, the maximum normalized microhardness is increased by 20% and the theoretical limit of this characteristic is substantially approached.
