Physical metallurgy has entered a new era of compositionally complex metallic alloys that show unprecedented combinations of mechanical properties enabling the design of more energy-efficient and economically viable applications. This project aims to generate new knowledge about how locally-resolved, nano-scale atomic arrangements control macroscopic deformation behavior in these materials and develop a fundamental understanding of their processing-structure-fracture toughness relationships. Expected outcomes include an enhanced capacity to design materials with damage-tolerant properties superior to existing alloys from bottom up, thereby allowing for commercial benefits throughout transportation, defense, and biomedical device sectors.Read moreRead less
Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on ....Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on twinning. The formation of crystalline twins is known to dictate the strength of the light metal magnesium. A fuller understanding of the effect of twinning on strength in this metal will provide much needed confidence to implement it more widely in energy saving applications.Read moreRead less

The project will produce a design framework for additively manufactured (3D printed) metal structures. The project will develop open source algorithms for predicting (i) mechanical properties of 3D printed metals for given printing parameters and (ii) internal stresses and distortions arising from the printing process. Underpinned by experiments on structural components and structural reliability analyses, models will be calibrated for the nonlinear analysis of 3D printed structures, and a methodology will be set out for designing 3D printed metal structures with acceptably low probability of failure.

Summary
Probing the nanomechanics of single grain boundary with decorated solutes. Grain boundaries (GBs) are thermodynamically susceptible to attract solutes to reduce system energy. Elaborately manipulating the GB nanostructure and chemistry via segregation can essentially be conducive, rather than detrimental, to materials performance. However, the underlying mechanism of GB segregation and its detailed effect on material properties remain elusive due to the GB complexities in the polycrystals.

Elaborately manipulating the GB nanostructure and chemistry via segregation can essentially be conducive, rather than detrimental, to materials performance. However, the underlying mechanism of GB segregation and its detailed effect on material properties remain elusive due to the GB complexities in the polycrystals. Through correlative in-situ nanomechanical testing and atom probe tomography, this project aims to unravel the rationale of segregation behaviour of individual GBs and its effectiveness to enhance the material performance, and hence enable nanostructural design of advanced metallic materials with unprecedented properties.Read moreRead less

This is significant because optimisation of the hot-forging route of the most commonly used Alloy 718 will enable targeted control of its nanoscale precipitate microstructure leading to substantial increases in the high-temperature strength. The expected scientific outcomes are new physical metallurgy knowledge of the microstructure-property relationships of superalloys. The expected technological and societal outcomes include enhanced aero-engine material performance, creating benefits such as shorter flights over longer distances, and safer, more fuel-efficient air travel.Read moreRead less

Australian manufacturers of 3D printed titanium products face grand challenges in affordably producing useable and reliable as-printed products because the 3D printing process may create unfavourable material characteristics. To ensure products meet acceptance criteria, manufacturers usually apply expensive and time-consuming post processes such as heat treatment. This project aims to discover how alloy composition can be modified to produce more favourable material characteristics directly from 3D printing, preventing the need for post processing. Australian manufacturers will likely benefit through a streamlined manufacturing process resulting in increased profitability in existing markets as well as expansion into new global markets.Read moreRead less
