Tensile plasticity with enhanced β-relaxation in high-energy metallic glass wires
Source abstract
Abstract
本文通过Taylor–Uitovsky方法成功制备了高质量Fe基、 Ni基、 Co基非晶丝. 与相同成分的传统非晶合金相比, 该非晶丝表现出普遍的β弛豫增强和更高的能量状态, 可以认为是高回春态的非晶丝. 值得注意的是, 这种非晶丝的能量增强率达到了216.38%, 是目前各种增强非晶合金能量状态方法中的最高值. 研究发现, β弛豫的增强归因于结构异质性引起的高能量状态, 从而使得非晶丝具有优良的力学性能, 跟相同成分的非晶条带相比, 其断裂强度提高至3240 MPa, 拉伸塑性应提高至1.7%. 本研究从β弛豫的角度实现了高能态的非晶合金的制备, 为打破强度和拉伸塑性之间的权衡提供了一个新见解.
