Investigation of Compressive and Tensile Behavior of Stainless Steel/Dissolvable Aluminum Bimetallic Composites by Finite Element Modelling and Digital Image Correlation
Download2021-01-01
Li, X., Ghasri-Khouzani, M., Bogno, A.-A., Liu, J., Henein, H., Chen, Z., Qureshi, A.J.
This study reports fabrication, mechanical characterization, and finite element modeling of a novel lattice structure based bimetallic composite comprised of 316L stainless steel and a func-tional dissolvable aluminum alloy. A net-shaped 316L stainless steel lattice structure composed of diamond...

The potential exists to use ultrasonic shear velocity for real time microstructure assessment of the quenching step in the teat treatment of L80 steel pipe. L80 steel samples were austenitized and subsequently cooled in different quench mediums (water, oil, heated oil, air and furnace) to produce...

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...

Cubic metallic alloys generally grow along 〈100〉 directions due to the anisotropy of the solid-liquid interfacial energy. Under rapid solidification conditions, dendrites may deviate from 〈100〉 and develop unusual morphologies. Here, Al-alloy droplets (Al-4.5Cu, Al-10Si, Al-1.9Fe, Al-33Cu, all in...
