A validated analytical-numerical modelling strategy to predict residual stresses in single-track laser deposited IN718 (2018)
Journal Article

Direct Energy Deposition (DED) is being increasingly used to repair high value components that have been damaged in-service. The uptake of DED and laser cladding operations for repair is inhibited by accurate modelling techniques. Often the repair pr...

Crystallographic texture can be rapidly determined by electrochemical surface analytics (2018)
Journal Article

Orientation affects application-defining properties of crystalline materials. Hence, information in this regard is highly-prized. We show that electrochemical jet processing (EJP), when coupled with accurate metrological appraisal, can characterise c...
