Journal ArticleDOI
Interface affected zone for optimal strength and ductility in heterogeneous laminate
Chongxiang Huang,Yanfei Wang,Xiaolong Ma,Sheng Yin,Heinz Werner Höppel,Mathias Göken,Xiaolei Wu,Huajian Gao,Yuntian Zhu,Yuntian Zhu +9 more
TL;DR: In this article, the authors report in situ high-resolution strain mapping near interfaces in a copper-bronze heterogeneous laminate, which revealed the existence of IAZs.
Journal ArticleDOI
Improved back stress and synergetic strain hardening in coarse-grain/nanostructure laminates
TL;DR: In this paper, the effect of back stress on the mechanical behaviors of heterogeneous material is studied in two modeled heterogeneous laminates, i.e. laminated structure with a nanostructured (NS) Cu-Zn alloy layer sandwiched between two coarse-grained (CG) pure Cu layers.
Journal ArticleDOI
Extra strengthening in a coarse/ultrafine grained laminate: Role of gradient interfaces
Yanfei Wang,Yanfei Wang,Mingsai Wang,Xiaotian Fang,Fengjiao Guo,H.Q. Liu,Ronald O. Scattergood,Chongxiang Huang,Yuntian Zhu,Yuntian Zhu +9 more
TL;DR: In this paper, the effect of gradient interfaces on mechanical behavior was investigated in a laminated Cu-30Zn sample composed of coarse-grained and ultrafine grained layers, and tensile tests revealed a superior strength-ductility synergy with extraordinary strengthening and work hardening.
Journal ArticleDOI
Hetero-deformation induced (HDI) hardening does not increase linearly with strain gradient
Yanfei Wang,Chongxiang Huang,Xiaotian Fang,Heinz Werner Höppel,Matthias Göken,Yuntian Zhu,Yuntian Zhu +6 more
TL;DR: In this article, the authors reported that HDI hardening does not increase linearly with increasing strain gradient in the interface-affected zone, which is because some GND pileups may be absorbed by the interface and consequently does not contribute to the increase in strain gradient.
Journal ArticleDOI
Quantifying the synergetic strengthening in gradient material
TL;DR: In this paper, a simple procedure based on the relationship between hardness increment and yield strength increment of corresponding homogeneous counterparts is proposed to quantitatively predict the synergetic strengthening effect in gradient-structured Cu-30-wt%Zn.
