Three different AlFeNb alloys of various compositions were prepared by arc melting. X‐ray diffraction (XRD) investigation of the melted samples proved the presence of two phases identified as a bcc α(Fe,Al) solid solution and a hexagonal C14 (Fe,Al)2Nb Laves phase. Subsequent electrochemical treatment allowed for a selective dealloying of the α(Fe,Al) or respective FeAl phase and resulted in releasing...
CuSn alloys with a hyper‐eutectic composition (97.53 at% Sn, 2.42 at% Cu and 0.05 at% impurities) were melted in a Bridgman‐type furnace and cooled at different velocities ranging from free fall to 13 µm/s. The formation of the intermetallic phase along the alloys, as well as the size, distribution and microstructure were observed as a function of cooling speed, showing different particle morphologies...
