TLDR
In this paper, the hardness and Young's modulus increased with the increase of sintering temperature up to 1300 °C, but the Young modulus decreased with the further increase of Sintering temperatures at 1400 and 1500 °C.About:

Luminescence variations in hydroxyapatites doped with Eu2+ and Eu3+ ions
TL;DR: It is proposed that fluorescence measurements are an excellent way of qualitatively determining the phase composition of europium-doped hydroxyapatite powders, since powders that exhibit a blue emission contain substantial amounts of Ca-D HAp, allowing the determination of the presence of this phase in mixed-phase hydroxyAPatites.

Hydroxyapatite and tricalcium phosphate composites with bioactive glass as second phase: State of the art and current applications.
TL;DR: The state of the art and current applications of composites, based on HA or TCP with bioactive glass as second phase, are presented and discussed and a special emphasis is given to the processing and mechanical behaviour of these systems, together with their biological implications, as a function of the composition of the glass employed as secondphase.

An improved technique for determining hardness and elastic modulus using load and displacement sensing indentation experiments
Warren C. Oliver,George M. Pharr +1 more
TL;DR: In this paper, the authors used a Berkovich indenter to determine hardness and elastic modulus from indentation load-displacement data, and showed that the curve of the curve is not linear, even in the initial stages of the unloading process.

Young's modulus of trabecular and cortical bone material: ultrasonic and microtensile measurements.
TL;DR: The results suggest that when considered mechanically, cortical and trabecular bone are not the same material.

Elastic properties of human cortical and trabecular lamellar bone measured by nanoindentation
TL;DR: An experimental investigation was undertaken to measure the intrinsic elastic properties of several of the microstructural components of human vertebral trabecular bone and tibial cortical bone by the nanoindentation method, and differences in the measured moduli are statistically significant.

Mechanical properties of sintered hydroxyapatite and tricalcium phosphate ceramic.
TL;DR: In this article, the ultimate values for compressive strength, Young's modulus, and toughness of cylindrical specimens of unitary aspect ratios and uniform grain-size distributions were extrapolated for hydroxyapatite (HAP) to 70 MPa, 9.2 GPa, and 0.36 J cm(-3).

The elastic properties of trabecular and cortical bone tissues are similar: results from two microscopic measurement techniques.
TL;DR: The results suggest that elasticity of trabecular tissue is within the range of that of cortical bone tissue and that nanoindentation as a technique for measurement of Young's modulus in anisotropic bone is not limited.
