Journal ArticleDOI
Giant magnetic-field-induced strains in polycrystalline Ni–Mn–Ga foams
Markus Chmielus,Markus Chmielus,X. X. Zhang,X. X. Zhang,Cassie Witherspoon,David C. Dunand,Peter Müllner +6 more
TL;DR: It is demonstrated that introducing pores smaller than the grain size further reduces constraints and markedly increases MFIS to 2.0-8.7%.
Journal ArticleDOI
Efficient Design-Optimization of Variable-Density Hexagonal Cellular Structure by Additive Manufacturing: Theory and Validation
Journal ArticleDOI
Powder bed binder jet printed alloy 625: Densification, microstructure and mechanical properties
Amir Mostafaei,Erica Stevens,Eamonn T. Hughes,Shannon D. Biery,Colleen Hilla,Markus Chmielus +5 more
TL;DR: In this paper, the effect of sintering temperature on density, microstructure, phase formation and mechanical properties of power bed binder jet printed alloy 625 parts was investigated, and the as-received powder was subjected to differential scanning calorimetry analysis, and printed samples were cured and sintered at various temperatures under high vacuum.
Journal ArticleDOI
Microstructural evolution and mechanical properties of differently heat-treated binder jet printed samples from gas- and water-atomized alloy 625 powders
TL;DR: In this paper, the effect of powders resulting from different atomization methods on properties of binder jet printed and heat-treated samples was investigated, and the results showed that the difference in microstructural evolution results in different mechanical properties.
Journal ArticleDOI

TL;DR: In this article, the authors investigated the oxidation behavior of several stainless steels and nickel-based superalloys exposed to supercritical water at 800°C for 12h and found that the thickness of the oxide layers formed was as high as 1μm, comprising different spinel structures.
