Fracture Toughness Determinations by Indentation

TL;DR: In this article, it was shown that the thickness of the interface layer can be altered by annealing at temperature higher than the ternary eutectic temperature (904°C), in a few minutes time.

TL;DR: In this article, an assemblage des ceramiques par chauffage micro-ondes is described, along with a description of the procedure of Ques Tech and the result of the result.

TL;DR: In this paper, a reactive hot pressing route (1830°C, 3'min, 30'MPa) was used to obtain ZrB2-SiC ceramics containing 8'vol.% of multi-wall carbon nanotubes (MW-CNT).

TL;DR: In this article, three formulations of ion-substituted calcium hydroxyapatite (HAp) biomaterials were prepared via a wet-chemical precipitation method.

TL;DR: In this article, the authors examined the nature of microcracking about small-scale indentations in two highly brittle solids, sapphire and carborundum, and found that cleavage steps comprise the main source of obstruction to lattice restoration across the interfaces.

TL;DR: In this article, a three part study of indentation fracture in the plastic contact regime is presented, where the first part summarizes the observations of fracture and develops a fracture classification scheme, the second part discusses the implications of the fracture characterization for fracture toughness determinations, and abrasive wear and low velocity erosion prediction.

TL;DR: In this article, a simple method for studying slow crack growth is described, which entails measurements of load relaxation at constant displacement using a double torsion specimen, and it is demonstrated that the data generated using this technique are in excellent agreement with data obtained using the more complex conventional techniques, for a range of materials - steel, titanium, glass, aluminum oxide, PMMA.
