Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites
Advanced Engineering Materials, EarlyView.Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Production of MgO/TiC Composites From MgO‐C Recyclates Using Spark Plasma Sintering
Advanced Engineering Materials, EarlyView.Using the spark plasma sintering technique, MgO/TiC composites are manufactured from recycled MgO‐C refractories stemming from the steel production that were mixed with titanium powder. This article shows, how the size of the Ti grains and their distribution in the powder mixture affect the local carbon concentration in TiC.

Direction of Arrival Estimation with Coprime Arrays
, 2020 L'estimation de la direction d'arrivée (DOA) des sources avec les réseaux coprimes a été beaucoup étudiée grâce à leurs degrés de liberté (DOFs) élévés et leurs meilleures performances d'estimation. La recherche existante dans ce domaine évolue vers deux orientations, qui sont les méthodes basées sur le difference coarray, qui tentent d'augmenter les ...
