Co3W2Si intermetallic compound was synthesized by mechanical alloying (MA) of W, Co and Si elemental powder mixtures. The phase composition of the milled products was evaluated by X-ray diffraction (XRD) analysis. Morphological evolutions were characterized by transmission electron microscopy (TEM). The results showed that high energy ball milling performed in the present work led to the format...

Intermetallic compounds have been studied for their potential application as structural wear materials or coatings on engineering steels. In the present work, a newly designed intermetallic composite in a Ni-Mo-Si system was fabricated by arc-melting process with commercially pure metal powders as starting materials. The chemical composition of this intermetallic composite is 45Ni-40Mo-15Si (at...

?-Al13Fe4 is one of the common Fe-containing intermetallic compounds (FIMCs) that forms during solidification in Al alloys. Silicon (Si) as impurity or solute alloys easily doped into ?-Al13Fe4, which not only causes compositional variation but also modifies lattice parameters, and some circumstances, changes crystal structure ?-Al13Fe4. In this study, multiple Al-Fe Al-Fe-Si solidified equilib...

The elimination of the FexAly type phases was considered the solution to low ductility presented in aluminum-steel welded joints. Recently, the researches do not seek the suppression but the control of the thickness of these compounds. In this work, Al-Fe joints were manufactured by solid state and fusion welding, looking for controlling the formation of intermetallic comp...

A new, oxygen-stabilized intermetallic compound was identified in sintered, pre-alloyed rare-earth iron powder samples. Its composition corresponds to formula R.-Fe^Oj, and its crystal structure belongs to space group Imjnu The presence of these compounds has been observed, so far, in several K-Fe-0 systems, with R = Gd, Tb, Dy, Ho* Er and Y.

Intermetallide phase formation was studied in a powdered Fe–Al system under layer by layer laser cladding with the aim of fabricating the gradient of properties by means of changing the Fe–Al concentration ratio in the powder mixture from layer to layer. The relationships between the laser cladding parameters and the intermetallic phase structures in the consecutively cladded layers were determ...
