Modeling grain size dependent optimal twin spacing for achieving ultimate high strength and related high ductility in nanotwinned metals
We have developed a mechanism-based plasticity model of nanotwinned metals to investigate the effect of twin spacing on strength, ductility and work hardening rate of such materials. In particular, the unique roles of dislocation pile-up zones near twin and grain boundaries, as well as twinning partial dislocations, in strengthening and work hardening are incorporated in the model. Competition ...
متن کاملAre nanotwinned structures in fcc metals optimal for strength, ductility and grain stability?
The optimality of nanotwinned structures in imparting maximum strength and stability has been investigated by performing atomistic simulations of dislocation interactions with various types of grain boundaries. By developing an understanding of the mechanism of the instability, we predict that nanocrystalline metals with grain sizes below 50 ± 10 nm or 70 ± 10 nm (in Cu) are inherently unstable...
متن کاملAre some nanotwinned fcc metals optimal for strength, ductility and grain stability?
Here we investigate whether certain face-centered cubic metals display a superior behavior of nanotwinned structures compared to others. We also address the question of an optimal lamella thickness that yields maximum strength and stability. Our analysis of the intrinsic stacking fault energies, csf , and the unstable stacking fault energies, cus, of Al, Pd, Cu and Ag, as well as our atomistic ...
متن کاملUltra-Fine Grained Dual-Phase Steels
This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...
متن کاملOptimization of ECMAP parameters in production of ultra-fine grained Al1050 strips using Grey relational analysis
Production of lightweight metals with a higher strength to weight ratio is always the main goal of researchers. In this article, equal channel multi angular pressing (ECMAP) process as one of the most appealing severe plastic deformation (SPD) methods on production of ultra-fine grained (UFG) materials studied. Two main routes A and C investigated by FEM and compared with each other from differ...
