Zr61Ti2Cu25Al12非晶态合金在四点弯曲加载模式下的弯曲弹性极限OA
Flexural elastic limit of Zr61Ti2Cu25Al12 amorphous alloy under four-point bending loading mode
按照当前金属材料弯曲性能测试标准中推荐的跨厚比设计Zr61Ti2Cu25Al12非晶态合金的弯曲试验,试样将发生大挠度弹性变形.经过推导证明,弯曲试样不发生大挠度弹性变形的跨厚比上限取决于材料的弹性应变极限,锆基非晶态合金的弹性应变极限为2%,在四点1/4弯曲模式下不发生大挠度弹性变形的跨厚比上限值为22.在保证小挠度变形的前提下,通过四点弯曲循环加载-卸载试验,Zr61Ti2Cu25Al12合金试样最外表层发生初始剪切变形所对应的弯曲屈服应力约…查看全部>>
The bending test of Zr61Ti2Cu25Al12 amorphous alloy was designed according to the span-thickness ratio recommended in the current metal material bending performance test standard,and the specimen would undergo large deflection elastic deformation.It was proved that the upper limit of the span-to-thickness ratio of the bending specimen without large deflection elastic deformation depended on the elastic strain limit of the material.The elastic strain limit of…查看全部>>
