摘要：
Applications of magnesium alloys as biodegradable orthopaedic implants are critically dependent on the mechanical integrity of the implant during service. In this study, the stress corrosion cracking susceptibility of sand-cast Mg-Al-Zn alloy in modified-simulated body fluid was evaluated using the slow strain rate test method. The study suggests that the stress corrosion cracking susceptibility of the sand-cast magnesium alloy is not substantial and this aspect should not be a concern for its implant applications.
