Biocompatibility describes the interactions between the living system and the materials introduced into this system [3].
Bone-like apatite can form on the surface of bioactive materials when they are immersed in SBF, which is considered to be one of the characteristics of bioactivity for biomaterials.
Because of its similarity to the inorganic component of bone and tooth structure, synthetic hydroxypapatite was one of the first materials considered for coating metallic implants.

Consolidation of nanocrystalline/amorphous metallic powder, ribbon or wires into bulk materials is often considered difficult because of the material's poor ductility.
Experimental Procedure Al90Fe7Cr3 and Al90Fe5Cr5 powder alloys were prepared by high-energy ball milling using high-purity elemental metals as starting materials.

Introduction Fig. 1 Schematic view of cone cracking with the spherical SiC indenter on glass sheet Slow crack growth in brittle materials is usually difficult to measure and observe in test.
Crack initiation in brittle materials is mainly caused by tensile stress, and the radial stress at the contact circle rapidly degrades along the depth and becomes compressive.
The relevant mechanical parameters for these materials were: Young's modulus, E = 320GPa, and Poisson's ratio, v = 0.15, for SiC; E = 70GPa, v = 0.2, for soda-lime glass.
