研制了一种微尺度拉伸疲劳试验系统，可以对块状材料制成的试样进行试验。在该系统中，探针附着在微机械臂上，微机械臂可以实现精确的初始定位和施加拉伸应力。本文介绍了粗晶镁合金AZ31的拉伸试验和拉伸疲劳试验的系统和结果。拉伸试验表明，该系统能准确地对微尺度试样施加拉应力，微尺度结构的抗拉强度远高于块状材料。拉伸疲劳试验表明，该系统能够承受预期的循环拉应力。
We developed a micro-scale tensile fatigue test system, which can test specimens fabricated from bulk materials. In this system, a probe is attached to a micro-manipulator and the micro-manipulator enables accurate initial positioning and applying tensile stress. In this paper, we present the system and the result of tensile tests and tensile fatigue tests on the specimens which are made of coarse-grained magnesium alloy, AZ31. The tensile tests suggests that the system can apply accurate tensile stress to the micro-scale specimens and the tensile strength of micro-scale structures is much stronger than that of bulk materials. And the tensile fatigue test indicates that the system can apply intended cyclic tensile stress.
