Microstructure and mechanical properties of super-strong nanocrystalline tungsten processed by high-pressure torsion
Qiuming Wei,H. Zhang,Brian E. Schuster,Brian E. Schuster,K.T. Ramesh,Ruslan Z. Valiev,Laszlo J. Kecskes,Robert J. Dowding,L. S. Magness,Kyu Cho +9 more
TL;DR: In this article, the nanocrystalline tungsten (nc-W) was obtained by high-pressure torsion (HPT) at low temperature (500°C) by transmission electron microscopy (TEM).
Journal ArticleDOI
High strain-rate compressive deformation behavior of the Al0.1CrFeCoNi high entropy alloy
Nilesh Kumar,Q. Ying,Xu Nie,Rajiv S. Mishra,Z. Tang,Peter K. Liaw,R.E. Brennan,K.J. Doherty,Kyu Cho +8 more
TL;DR: In this article, the deformation behavior of an Al0.1CrFeCoNi HEA at high strain-rate (HSR) was analyzed using split-Hopkinson pressure bar.
Journal ArticleDOI
Prediction models for the yield strength of particle-reinforced unimodal pure magnesium (Mg) metal matrix nanocomposites (MMNCs)
Chang-Soo Kim,Il Sohn,Marjan Nezafati,J. B. Ferguson,Benjamin F. Schultz,Zahra Bajestani-Gohari,Pradeep K. Rohatgi,Kyu Cho +7 more
TL;DR: In this article, the authors examined the yield strength of particle-reinforced MMNCs by considering individual strengthening mechanism candidates and yield strength prediction models and found that the incorporation of the coefficient of thermal expansion mismatch and modulus mismatch will considerably overestimate the experimental yield strength.
Journal ArticleDOI
Microstructure, precipitates and hardness of selectively laser melted AlSi10Mg alloy before and after heat treatment
TL;DR: In this paper, the microstructure and precipitates within selectively laser melted (SLM) AlSi10Mg alloys in the as-built state and after T6 heat treatment were examined and correlated to the hardness evolution.
Journal ArticleDOI
Microstructure and tensile property of a novel AlZnMgScZr alloy additively manufactured by gas atomization and laser powder bed fusion
TL;DR: In this paper, high strength aluminum alloy can be fabricated by laser powder bed fusion (LPBF) through alloy design and microstructural control, and the results demonstrate that high strength Al-6Zn-2Mg alloys with 1'wt% (Sc,Zr) additively manufactured by LPBF using gas atomized powders.
