Formation study of nanostructured Cr100−xCox (x=10, 90) alloys

Application of Harmonic Structure Design to Biomedical Co–Cr–Mo Alloy for Improved Mechanical Properties

“…The significant peak broadening is an evidence of the grain refining due to the severe plastic deformation caused by the ball milling. 19,20) It would also be worth mention that the XRD peak width increased with increasing milling time. Such an increment in the XRD peak width suggests that the increasing milling time incorporates higher degree of grain refinement in the milled powders and accumulation of lattice defects.…”

Structural Analysis and Magnetic Properties of FeCo Alloys Obtained by Mechanical Alloying

“…A great number of techniques have been used to synthesize the FeCo powders, like reduction reactions [3], plasmagas-condensation [4], wet chemical technique [5], and polyol [6]. Among the various synthesis methods, mechanical alloying (MA) is a method that creates a large number of crystal defects and stacking faults due to the severe plastic deformation that results from the high energy supplied to the system [7,8]. This enables structural changes such as allotropic transformations [9][10][11] which normally occur at high temperatures [12].…”

Extended solid solubility of a Co–Cr system by mechanical alloying

“…Additionally, in this diagram, the formation of different metastable phases can be observed. In this work, it is demonstrated that MA modify the solid solubility of the Co-Cr system in 7 h of milling time, when a shaker mixer/mill SPEX is used (high energy mill), in contrast with results previously reported [5,[11][12][13] by mechanical alloying using a planetary ball mill in larger milling times.…”
