The use of handmade particulate reinforced alloy horseshoes (MMC metal matrix composites) was tested in a field study on 15 riding and draught horses. All horseshoes have been tempered after having been manually forged and tested concerning their surface imperfection. Forging temperature ranged between 350 degrees and 420 degrees C. Horseshoes in series A consisted of particulate reinforced wrought alloy (22% Al2O3 in alloy matrix). 11 shoeing periods with a duration of mean = 49.7 days (sd = 13.6) were evaluated. Horseshoes in series B consisted of particulate reinforced foundry alloy (20% SiC in alloy matrix), 5 shoeing periods were evaluated with a duration of mean = 45.4 days (sd = 7.9). Series C tested horseshoes made of particulated reinforced coextruded wrought alloy evaluating 6 shoeing periods with a duration of mean = 49.2 days (sd = 18.7). Service of the tempered particulate reinforced alloy horseshoes was significantly higher compared to untempered alloy horseshoes. Mechanical and forging properties of tempered particulate reinforced alloy are satisfactory. Service is only suitable for riding horses but not for draught horses.
在一项针对15匹骑乘马和役用马的实地研究中，对手工制作的颗粒增强合金马蹄铁（MMC金属基复合材料）的使用情况进行了测试。所有马蹄铁在手工锻造后都进行了回火处理，并对其表面缺陷进行了测试。锻造温度在350摄氏度至420摄氏度之间。A组马蹄铁由颗粒增强变形合金（合金基体中含22% Al2O3）组成。评估了11个装蹄周期，平均时长为49.7天（标准差 = 13.6）。B组马蹄铁由颗粒增强铸造合金（合金基体中含20% SiC）组成，评估了5个装蹄周期，平均时长为45.4天（标准差 = 7.9）。C组测试的马蹄铁由颗粒增强共挤变形合金制成，评估了6个装蹄周期，平均时长为49.2天（标准差 = 18.7）。与未回火的合金马蹄铁相比，回火后的颗粒增强合金马蹄铁的使用寿命显著更长。回火颗粒增强合金的机械性能和锻造性能令人满意。其使用寿命仅适用于骑乘马，不适用于役用马。
