Abstract In this study, the structure and mechanical properties of near-eutectic refractory Al 24 Cr 11 Nb Ti 37 Zr 17 , 20 25 10 28 15 22 (at.%) high entropy alloys were investigated. Both had a hypoeutectic structure, while alloy hypereutectic one. The proeutectic phase in was ordered B2 – C14 Laves phase. all three alloys, eutectic regions possessed fine lamellar composed mixture phases. den...

The hypoeutectic composite material composed of BCC phase and in situ precipitated Ti5Si3 was prepared by adding Si into MoNbTaTiV high-entropy alloy. obvious oriented formed eutectic with the inter-dendritic area, which leads to excellent properties composite. alloy exhibits ultra-high yield stress 718 MPa at 1200 °C compression plasticity. After reaching maximum strength, dynamic recovery (DR...

Unique quantitative bioaccessibility data has been generated, and the influence of surface/material and test media characteristics on the elemental release process were assessed for silicon containing materials in specific synthetic body fluids at certain time periods at a fixed loading. The metal release test protocol, elaborated by the KTH team, has previously been used for classification, ra...

Graphene-based metallic nanocomposites are promising materials for applications where tailored strength and functionality required such as space automotive industries. Additive manufacturing, specifically 3D printing, is currently considered a revolutionary process to tailor engineer certain applications. Herein, we report fast reliable approach prepare mechanically robust, ductile high thermal...
