Self-Propagating Reactions Induced by Mechanical Alloying

An article concerning self-propagating reactions induced by mechanical alloying, presented by Sigma-Aldrich.com.

Biomedical Implant Devices Fabricated from Low Young’s Modulus Titanium Alloys Demonstrating High Mechanical Biocompatibility

Biomedical implants are essentially foreign substances within the human body that must survive many years’ exposure to demanding mechanical and physiological conditions. Despite these challenges, metal implants have been widely used to substitute for or rebuild hard tissues such as bones and teeth.
