Structural changes during synthesizing of nanostructured W–20wt% Cu composite powder by mechanical alloying

Nanostructure and mechanical behavior of metastable Cu–Cr thin films grown by molecular beam epitaxy

“…Non-equilibrium alloys can not only be obtained by deposition techniques: they can also be obtained by mechanical alloying (MA) from powder mixtures of the constituent elements [14], with numerous studies reporting on the formation of supersaturated solid solutions (SSSSs) of Nb [15], Cr [16,17], Mo [18,19], V [20], W [21,22] and Fe [23] within ball-milled binary Cu alloys. Moreover, "mechanical alloying in bulk form" can be achieved via severe plastic deformation (SPD) [24].…”

Characterization of fine-grained W–10wt.% Cu composite fabricated by hot-shock consolidation

“…It is difficult to achieve full or near density by LPS due to the poor solubility of W and Cu [4]. Therefore, activated sintering [5] and mechanical alloying [6,7] were used to enhance the sinterability of W-Cu composites. However, these methods led to unsatisfactory thermal and electrical properties due to contaminations generated during the process.…”

Reverse martensitic transformation in alumina–15vol% zirconia nanostructured powder synthesized by high energy ball milling

“…Most commonly the crystallite size is determined by measuring the Bragg peak width at the half maximum intensity and using the Williamson-Hall method [23]:…”

“…On the other hand, the rate of stabilization is controlled by movement of cations which is a million fold smaller than that of the oxygen ions. HEBM provides positive thermodynamic driving force for monoclinic to tetragonal transformation occurrence [10] because HEBM is known to induce formation of nonequilibrium phases [20][21][22][23][24][25].…”
