摘要 本文介绍了一种简单评估准晶材料Al59Cu2 5.5Fe1 2 .5B3 的断裂韧性的方法。根据维氏(Vickers)压痕试验法测量的显微硬度和利用扫描电子显微镜 (SEM )测定压痕的径向裂纹尺寸 ,计算出断裂韧性为 1.34MPam-1 / 2 。 A simple method, which is used to test the fracture toughness for Al 59 Cu 25.5 Fe 12.5 B 3 quasicrystals, was introduced. According to the Vickers microhardness and radial crack size tested by scanning electron microscopy (SEM), the fracture toughness of this quasicrystal is evaluated as 1.34 MPam -1/2 . The results are basically consistent with those reported in other literatures.
