High strength nanostructured Al-based alloys through optimized processing of rapidly quenched amorphous precursors
Kim, Song-Yi; Lee, Gwang-Yeob; Park, Gyu-Hyeon; Kim, Hyeon-Ah; Lee, A-Young; Scudino, Sergio; Konda Gokuldoss, Prashanth; Kim, Do-Hyang; Eckert, Jürgen; Lee, Min-Ha (Journal article; Peer reviewed, 2018)We report the methods increasing both strength and ductility of aluminum alloys transformed from amorphous precursor. The mechanical properties of bulk samples produced by spark-plasma sintering (SPS) of amorphous Al-Ni-Co-Dy ... -
Microstructure and mechanical properties of Al-Cu alloys fabricated by selective laser melting of powder mixtures
Wang, Pei; Deng, L.; Konda Gokuldoss, Prashanth; Pauly, Simon; Eckert, Jürgen; Scudino, Sergio (Journal article; Peer reviewed, 2018)Selective laser melting was used to in-situ fabricate Al-xCu (x = 4.5, 6, 20, 33 and 40 wt%) samples from mixtures of Al-4.5Cu/Cu powders. The insufficient Cu solute diffusion during the layer-by-layer processing results ... -
Reciprocating sliding wear behavior of high-strength nanocrystalline Al84Ni7Gd6Co3 alloys
Wang, Zhi; Georgarakis, Kostas; Zhang, W. W; Konda Gokuldoss, Prashanth; Eckert, Jürgen; Scudino, Sergio (Journal article; Peer reviewed, 2017)Nanocrystalline Al-Ni-Gd-Co alloys with exceptionally high hardness have been recently developed from amorphous precursors. In the present work, the reciprocating sliding wear in the gross slip regime of these novel ...
