Advancing electrochemical jet methods through manipulation of the angle of address (2017)
Journal Article

Electrochemical jet processing techniques have traditionally been considered to be limited to planar interactions with the electrolyte jet being maintained normal to the workpiece surface. In this study, the viability and resultant effects of articul... Read More about Advancing electrochemical jet methods through manipulation of the angle of address.

Transitory electrochemical masking for precision jet processing techniques (2017)
Journal Article

Electrochemical jet processing techniques provide an efficient method for large area surface structuring and micro-milling, where the metallurgy of the near-surface is assured and not adversely affected by thermal loading. Here, doped electrolytes ar... Read More about Transitory electrochemical masking for precision jet processing techniques.

Targeted rework strategies for powder bed additive manufacture (2017)
Journal Article

A major factor limiting the adoption of powder-bed-fusion additive manufacturing for production of parts is the control of build process defects and the effect these have upon the certification of parts for structural applications. In response to thi... Read More about Targeted rework strategies for powder bed additive manufacture.

Defect evolution in laser powder bed fusion additive manufactured components during thermo-mechanical testing (2017)
Conference Proceeding

The mechanical performance of additively manufactured (AM) components remains an issue, limiting the implementation of AM technologies. In this work, a new method is presented, to examine the evolution of defects in an Inconel 718 two-bar test specim...

Meso-scale defect evaluation of selective laser melting using spatially resolved acoustic spectroscopy (2017)
Journal Article

Developments in additive manufacturing technology are serving to expand the potential applications. Critical developments are required in the supporting areas of measurement and in process inspection to achieve this. CM247LC is a nickel superalloy th...

Enhanced sensing and conversion of ultrasonic Rayleigh waves by elastic metasurfaces (2017)
Journal Article

Recent years have heralded the introduction of metasurfaces that advantageously combine the vision of sub-wavelength wave manipulation, with the design, fabrication and size advantages associated with surface excitation. An important topic within met... Read More about Enhanced sensing and conversion of ultrasonic Rayleigh waves by elastic metasurfaces.

Electrolyte design for suspended particulates in electrolyte jet processing (2017)
Journal Article

The addition of particles (less than 1 μm) to electrolyte feedstocks results in marked changes to the morphology of deposits when electrolyte jet processing (EJP) compared to electrolyte only feedstocks. Through the use of a ‘carrier’ electrolyte in... Read More about Electrolyte design for suspended particulates in electrolyte jet processing.

Tribological behaviour of an electrochemical jet machinedtextured Al-Si automotive cylinder liner material (2017)
Journal Article

This paper investigates the use of Electrochemical Jet Machining to surface texture a hyper-eutectic Al-Si cylinder liner material. Samples were lapped to a 6?m finish followed by immersion in 1mol NaOH to expose the primary silicon colonies above th...

Fractal scan strategies for selective laser melting of ‘unweldable’ nickel superalloys (2017)
Journal Article

The high thermal gradients experienced during manufacture via selective laser melting commonly result in cracking of high γ/γ′ Nickel based superalloys. Such defects cannot be tolerated in applications where component integrity is of paramount import...

Controlling DC permeability in cast steels (2017)
Journal Article

Annealing (at multiple cooling rates) and quenching (with tempering) was performed on specimens of cast steel of varying composition. The aim was to devise a method for selecting the steel with the highest permeability, from any given range of steels... Read More about Controlling DC permeability in cast steels.
