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

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.
