Additive manufacturing of fine-grained and dislocation-populated CrMnFeCoNi high entropy alloy by laser engineered net shaping
Guan, Shuai; Wan, Di; Solberg, Klas; Berto, Filippo; Welo, Torgeir; Yue, Tai Man; Chan, K.C. (Journal article; Peer reviewed, 2019)The equiatomic CrMnFeCoNi high entropy alloy is additively manufactured by the laser engineered net shaping (LENSTM) process, and the solidification conditions, phase formation, as-deposited microstructures, and tensile ... -
Additive manufacturing of TiB2-containing CoCrFeMnNi high-entropy alloy matrix composites with high density and enhanced mechanical properties
Wang, Y.L.; Zhao, L; Wan, Di; Guan, Shuai; Chan, K.C. (Peer reviewed; Journal article, 2021)Near-fully dense CoCrFeMnNi high-entropy alloy (HEA) matrix composites reinforced with 5 wt% TiB2 nanoparticles were successfully additively manufactured via the laser-engineered net shaping technique. Compared to the ... -
A comparative study on nanoscale mechanical properties of CrMnFeCoNi high-entropy alloys fabricated by casting and additive manufacturing
Liu, Siqi; Wan, Di; Guan, Shuai; Fu, Yuequn; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2024)Additive manufacturing (AM) has emerged as a pioneering method for fabricating high entropy alloys (HEAs), yet a comprehensive comparison of their nanoscale mechanical properties with those produced by the conventional ... -
Fatigue of additively manufactured 316L stainless steel: The influence of porosity and surface roughness
Solberg, Klas; Guan, Shuai; Javad Razavi, Seyed Mohammad; Welo, Torgeir; Chan, Kang Cheung; Berto, Filippo (Journal article; Peer reviewed, 2019)The fatigue behaviour of additively manufactured (AM) 316L stainless steel is investigated with the main emphasis on internal porosity and surface roughness. A transition between two cases of failure are found: failure ... -
Formation of fully equiaxed grain microstructure in additively manufactured AlCoCrFeNiTi0.5 high entropy alloy
Guan, Shuai; Solberg, Klas; Wan, Di; Berto, Filippo; Welo, Torgeir; YUE, TM; Chan, KC (Journal article; Peer reviewed, 2019)In this work, the non-equiatomic high entropy alloy AlCoCrFeNiTi0.5 was additively manufactured via the laser engineered net shaping (LENS™) process. Contrary to the columnar grain microstructure commonly observed in ... -
Hydrogen embrittlement of additively manufactured AlCoCrFeNi2.1 eutectic high-entropy alloy
Wan, Di; Guan, Shuai; Wang, Dong; Lu, Xu; Ma, Jun (Peer reviewed; Journal article, 2022)AlCoCrFeNi2.1 eutectic high-entropy alloy (HEA) was fabricated in as-cast and additively manufactured (AM) states. The hydrogen embrittlement susceptibility of both materials was investigated through in-situ uniaxial tensile ... -
Microstructure and nanomechanical behavior of an additively manufactured (CrCoNiFe)94Ti2Al4 high-entropy alloy
Liu, Siqi; Wan, Di; Guan, Shuai; Fu, Yuequn; Ren, Xiaobo; Zhang, Zhiliang; He, Jianying (Peer reviewed; Journal article, 2021)Recent substantial studies indicate that high-entropy alloys (HEAs) possess superior mechanical performance, including exceptional strength, high creep resistance, etc. However, additive manufacturing (AM), a burgeoning ...
