Study on fatigue performance of magnesium alloy used in sports equipment by casting method

Abstract： This paper uses traditional casting method and squeeze casting method to prepare magnesium alloys used in sports equipment， and conducts fatigue performance tests. The test results show that magnesium alloys prepared by squeeze casting method The fatigue performance is much higher than that of magnesium alloys prepared by traditional casting methods. When used in sports equipment， it can enhance its toughness and extend its service life.
