Various kinds of amorphous alloys were developed and applied to the mechanical use due to the high strength as well as the electro-magnetic materials. Distribution aspect of the strength plays an important role in evaluation of the safety and reliability of the mechanical structures. In this study, distribution characteristics of tensile and fatigue properties of Fe base amorphous alloy ribbons were experimentally examined. Main conclusions obtained are summarized as follows ;(1) Distribution aspect of tensile strength at temperatures from RT to 300deg. C is governed by a common population distribution of Wiebull type having three parameters.(2) Crystalization begins to occur at 400deg.C and completed at 500deg.C.Tensile strength at 400deg.C has a distinct scatter due to the crystalization and the distribution characteristics are well explained by means of a concept of combined distribution.(3) Fabrication process of multi-plied composite plate was established such that the strength of the plate was given by integration of the strength for each ply of the amorphous ribbons.(4) It was found that the fatigue property in pulsating tension had a distinct scatter. Thus statistical procedure should be introduced to the machine design and the safety analysis.

各种非晶合金由于其高强度和电磁性能而被开发和应用于机械领域。强度的分布情况在评价机械结构的安全性和可靠性中起着重要的作用。本文对铁基非晶合金薄带拉伸和疲劳性能的分布特征进行了实验研究。主要结论如下：（1）室温至300 ℃拉伸强度的分布规律。C由具有三个参数的Wiebull类型的共同总体分布决定。(2)结晶在400 ℃开始，500 ℃完成，400 ℃抗拉强度因结晶而具有明显的分散性，并用组合分布的概念很好地解释了其分布特征。(3)建立了多层复合材料板的制造工艺，使得板的强度由非晶薄带的每层强度的积分给出。(4)结果表明，脉冲拉伸疲劳性能具有明显的分散性。因此，在机械设计和安全分析中应引入统计学方法。
