Mechanical Properties of Silicon Nitride in Different Morphologies: In Situ Experimental Analysis of Bulk and Whisker Structures.

ABSTRACT: Silicon nitride (Si₃N₄) is widely used in structural ceramics and advanced manufacturing due to its excellent mechanical properties and high-temperature stability. These applications always involve deformation under mechanical loads, necessitating a thorough understanding of their mechanical behavior and performance under load. However, the mechanical properties of Si₃N₄, particularly at the micro- and nanoscale, are not well understood. This study systematically investigated the mechanical properties of bulk Si₃N₄ and Si₃N₄ whiskers using in situ SEM indentation and uniaxial tensile strategies. First, nanoindentation tests on bulk Si₃N₄ at different contact depths ranging from 125
