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.

Key words： squeeze casting method;sports equipment;magnesium alloy;fatigue performance

鎂合金相較于其他金屬材料，擁有著比重小、比強(qiáng)度高等諸多優(yōu)點(diǎn)，因此被廣泛的應(yīng)用于減重、減震等方面，在汽車、船舶制造等行業(yè)都有著廣泛的應(yīng)用。（剩余4958字）
