Machinability and brittleness of glass-ceramics
TLDR
The relationship between the machinability and the brittleness of glass-ceramic materials is investigated in this paper, where the authors propose the use of a brittility index (B), given by the ratio of the hardness to the fracture toughness, as a parameter for estimating the machINability.About:

Brittleness index of machinable dental materials and its relation to the marginal chipping factor.
TL;DR: It was shown that as the BI increases so does the potential for marginal chipping, indicating that the BI of a material can be used as a predictor of the CF.

A set of indices based on indentation tests for assessment of rock cutting performance and rock properties
TL;DR: In this article, a simple interpretation method is developed, which quantifies the force- penetration response obtained from indentation tests, and validated by a set of full-scale linear cutting tests using a conical cutter for measuring the cutting performance in relieved and unrelieved conditions, i.e. cutter forces, specific energy, size distribution of rock cuttings.

Hardness, Toughness, and Brittleness: An Indentation Analysis
Brian R. Lawn,David B. Marshall +1 more
TL;DR: In this paper, the authors proposed an index of brittleness based on the ratio H/Kc, where H is hardness (resistance to deformation) and Kc is toughness.

Scratching and Grinding of a Machinable Glass-Ceramic with Weak Interfaces and Rising T-Curve
Hockin H.K. Xu,Said Jahanmir +1 more
TL;DR: In this paper, the authors examined the scratching and grinding response of a machinable mica-containing glass-ceramic relative to the base glass and found that the removal rates and the grinding forces correlate with the short-crack toughness instead of the conventional long-cracks toughness.

A comparative evaluation method of machinability for mica-based glass-ceramics
TL;DR: In this paper, the machinability of mica glass-ceramics is evaluated using a tool dynamometer using several samples with different chemical compositions and microstructures and the results are correlated with the microstructure and the hardness of the workpiece.

Brittleness of glasses by indentation
TL;DR: In this article, a method to estimate the brittleness of glasses is introduced by measuring the C/a ratios where C and a are characteristic crack and indentation diagonal lengths, respectively.
