Automated semantic segmentation of NiCrBSi-WC optical microscopy images using convolutional neural networks
Download2022-01-01
Rose, D., Forth, J., Henein, H., Wolfe, T., Qureshi, A.
Convolutional neural networks (CNNs) were used for the semantic segmentation of angular monocrystalline WC from NiCrBSi-WC optical microscopy images. This deep learning approach was able to emulate the laborious task of manual segmentation effectively, with a mean intersection over union (IOU)...

Lehmann, T., Rose, D., Ranjbar, E., Ghasri-Khouzani, M., Tavakoli, M., Henein, H., Wolfe, T., Qureshi, A.
Additive Manufacturing (AM) has the potential to completely reshape the manufacturing space by removing the geometrical constraints of commercial manufacturing and reducing component lead time, especially for large-scale parts. Coupling robotic systems with direct energy deposition (DED) additive...

Bhardwaj, N., Henein, H., Wolfe, T.
Fused filament fabrication (FFF) is a method used to fabricate initial prototypes out of polymeric materials with printed parts often being used as load carrying elements. The mechanical properties of various polymer materials produced under certain printing conditions exhibit superior strength...

Mercado Rojas, J.G., Ghasri-Khouzani, M., Wolfe, T., Fleck, B.A., Henein, H., Qureshi, A.J.
Metal matrix composites enhance the wear and corrosion properties of components in heavy-duty industries. This work reports the preliminary effects of process parameters such as current, linear speed, powder flow rate, nozzle angle, and powder, shield and center gases at the macro-scale and...
