Design of lightweight high-temperature structural materials based on Ti-Mo-Ta-Cr-Al refractory compositionally complex alloys, Part I: Phase stability and mechanical properties Open
This study presents the design and evaluation of Ti-rich refractory complex concentrated alloys (RCCAs) within the Ta-Mo-Ti-Cr-Al system, aiming for low density and high-temperature stability. Alloys containing 44–54 at% Ti were synthesize…
Microstructure and mechanical properties of a laser-based directed energy deposited Mo-Si-Ti alloy Open
This study focuses on the linkage between microstructure and mechanical properties at elevated temperatures of a Mo-20Si-52.8Ti (at.%) eutectic alloy produced by directed energy laser deposition (DED-LB). The alloy consists of a body cente…
The Creep‐Induced Micro‐ and Nanostructural Evolution of a Eutectic Mo–Si–Ti Alloy at 1200 °C Open
In the present study, the creep deformation mechanisms of a eutectic Mo–Si–Ti alloy (comprising a body‐centered solid solution and a hexagonal silicide) are verified. The microstructural changes occurring at the various microstructural len…
Unveiling the Intricacies of a Ductile‐Phase Toughened Intermetallic: An In‐Depth Exploration of a Eutectic Mo–Si–Ti Alloy and its Mechanical Behavior Open
Herein, the development of directional solidification for a novel high‐temperature Mo–20Si–52.8Ti (at%) ternary alloy using a modified Bridgeman type apparatus is presented. The resulting alloy exhibits a microstructure consisting of a bod…
Microstructure and Mechanical Properties of a Precipitation‐Strengthened Fe–Al–Nb Alloy Open
Fe–Al alloys provide an attractive property profile for applications at temperatures of up to 700 °C. Herein, a Fe–25Al–2Nb (at%) alloy is, manufactured on an application‐relevant scale. Preforms are cast and subsequently forged into a tur…
Phase Continuity, Brittle to Ductile Transition Temperature, and Creep Behavior of a Eutectic Mo–20Si–52.8Ti Alloy Open
Mo–Si–Ti alloys, like eutectic Mo–20Si–52.8Ti (at%), have previously been intensely investigated, owing to their excellent oxidation and creep resistance. To better understand high‐temperature mechanical behavior, a holistic assessment of …
Flexible Powder Production for Additive Manufacturing of Refractory Metal-Based Alloys Open
The quality and properties of metal powders are essential for powder metallurgical (PM) processes in general and for additive manufacturing (AM) processing routes in particular. Thus, a variety of atomization technologies were established …
Influence of Temperature and Plastic Strain on Deformation Mechanisms and Kink Band Formation in Homogenized HfNbTaTiZr Open
Due to its outstanding ductility over a large temperature range, equiatomic HfNbTaTiZr is well-suited for investigating the influence of temperature and plastic strain on deformation mechanisms in concentrated, body centered cubic solid so…
The Creep and Oxidation Behaviour of Pesting-Resistant (Mo,Ti)5Si3-Containing Eutectic-Eutectoid Mo-Si-Ti Alloys Open
In this study we present a series of light-weight (6.24 to 6.42 g/cm3), Ti-rich Mo-Si-Ti alloys (≥40 at.% nominal Ti content) with the hitherto best combination of pesting and creep resistance at 800 and 1200 °C, respectively. This has bee…
Intensive processing optimization for achieving strong and ductile Al-Mn-Mg-Sc-Zr alloy produced by selective laser melting Open
The Sc-containing Al[sbnd]Mn alloy system produced by additive manufacturing (AM) has recently presented exciting new opportunities to achieve a step-change in mechanical properties, but its processability remains unclear. In this work, th…
