铸造工艺对镁合金高尔夫球杆阻尼性能的影响

Effect of Casting Process on Damping Capacity of Magnesium Alloy for Golf Clubs

采用不同的铸造工艺参数进行了高尔夫球杆用新型Mg-Al-Zn-Ti镁合金试样的制备,并进行了试样阻尼性能的测试与分析。结果表明,随熔炼温度从680℃逐步增加到760℃、静置时间从10 min逐步增加到50 min或浇注温度从690℃逐步增加到750℃时,试样的阻尼系数先增大后减小、阻尼性能先提高后下降。与680℃熔炼相比,采用720℃熔炼时高尔夫球杆用新型Mg-Al-Zn-Ti镁合金的阻尼系数增大49%;与10 min静置相比,采用30 min静置时合金的阻尼系数增大33%;与690℃浇注相比,采用730℃浇注时合金的阻尼系数增大了25%。合金的熔炼温度、静置时间和浇注温度分别优选为720℃、30 min、730℃。

A new type of Mg-Al-Zn-Ti magnesium alloy samples for golf clubs were prepared by using different casting process parameters, and the damping property of the samples were tested and analyzed. The results show that with the melting temperature gradually increasing from 680 to 760 ℃, the resting time gradually increased from 10 min to 50 min or the pouting temperature gradually increasing from 690 to 750 ℃, the damping coefficient of the sample first increases and then decreases, and the damping property first increases and then decreases. Compared with melting at 680 ℃, the damping coefficient of the alloy is increased by 49% at melting temperature of 720 ℃, and compared with resting for 10 min, the damping coefficient of the alloy by resting for 30 min is increased by 33%, while compared with pouting at 690℃, the damping coefficient of the alloy by 730 ℃ is increased by 25%. The melting temperature, resting time and pouring temperature of the alloy are preferably by 720 ℃, 30 min and 730℃, respectively.
