Abstract Scope Magnesium (Mg) alloys possess great potential materials for use as temporary implants such as pins, wires, screws, plates, stents). Use of Mg alloys will completely avoid the cumbersome procedure of second surgery (which is required when such implants are constructed out of traditional materials such as titanium alloys or stainless steels). However, there are some limitations of Mg as a temporary implant. First, the high corrosion rates of Mg alloys in physiological environment may lead to loss in mechanical integrity of the implants. Secondly, the simultaneous action of the corrosive human-body-fluid and the mechanical loading can cause stress corrosion cracking (SCC) and corrosion fatigue (CF). SCC and CF Mg alloy implants are vastly unexplored research areas. This presentation provides an overview of the experimental results on SCC and CF of different Mg alloys in corrosive environments including the simulated body fluid (SBF), and discusses the associated fracture mechanisms.
