Effect of Sintering Atmosphere on Grain Shape and Grain Growth in Liquid‐Phase‐Sintered Silicon Carbide
TL;DR: In this paper, the authors investigated the effects of the sintering atmosphere on the interface structure and grain-growth behavior in 10-vol%-YAG-added SiC and showed that the growth behavior of SiC grains in a liquid matrix depends on the structure of the grain interface.

A Critical Evaluation of Indentation Techniques for Measuring Fracture Toughness: I, Direct Crack Measurements
TL;DR: In this paper, the application of indentation techniques to the evaluation of fracture toughness is examined critically, in two parts: the first part is focused on an approach which involves direct measurement of Vickers-produced radial cracks as a function of the indentation load.
