Extreme Ductility at the Nanoscale in Fe-based Alloys
نویسندگان
چکیده
A novel method for preparing and testing bending specimens in-situ the TEM has been developed. This method provides high visibility of the crack front and its associated plastic zone. This is significant because energy release rates can now be calculated at many points throughout the test based on crack tip opening displacement (CTOD), crack opening angle (COA), and crack advance. Further refinement of testing methods to do dark field imaging of dislocations would allow estimation of dislocation content vs. time and may provide insights into dislocation behavior.

A nanoscale co-precipitation approach for property enhancement of Fe-base alloys
Precipitate size and number density are two key factors for tailoring the mechanical behavior of nanoscale precipitate-hardened alloys. However, during thermal aging, the precipitate size and number density change, leading to either poor strength or high strength but significantly reduced ductility. Here we demonstrate, by producing nanoscale co-precipitates in composition-optimized multicompon...
متن کاملNanostructured Al–Fe alloys produced by e-beam deposition: static and dynamic tensile properties
Three different aluminum–iron alloys were produced by electron-beam deposition with the iron content in the range 1.15–1.71 at.%. These alloys did not contain any identifiable iron-bearing particles, and exhibited full density with high-angle grain boundaries in the micrometer range, and a sub-grain size typically smaller than 100 nm. The tensile deformation characteristics of the alloys were e...
متن کاملFinal report: Aluminium based Nanoeutectics: Synthesis and Microstructure
Abstract: The primary aim of the project was to explore the possibility of synthesising high strength multiphase eutectic alloys based on aluminium which also exhibits reasonable ductility. The approach used was to develop a multiscale microstructure including nanometer length scale eutectic colony using ternary alloys and evaluate their deformation behaviour. We have carried out work on two al...
متن کاملBreaking through the strength-ductility trade-off dilemma in an Al-Si-based casting alloy
Al-Si-based casting alloys have a great potential in various industrial applications. Common strengthening strategies on these alloys are accompanied inevitably by sacrifice of ductility, known as strength-ductility trade-off dilemma. Here, we report a simple route by combining rapid solidification (RS) with a post-solidification heat treatment (PHT), i.e. a RS + PHT route, to break through thi...
متن کاملNanoscale origins of the damage tolerance of the high-entropy alloy CrMnFeCoNi
Damage tolerance can be an elusive characteristic of structural materials requiring both high strength and ductility, properties that are often mutually exclusive. High-entropy alloys are of interest in this regard. Specifically, the single-phase CrMnFeCoNi alloy displays tensile strength levels of ∼ 1 GPa, excellent ductility (∼ 60-70%) and exceptional fracture toughness (KJIc>200 MPa√m). Here...
