Methods for obtaining alloys of the Cu-Mn-Ni system with the preliminary mechanical alloying of the components and by direct alloying are compared. It is established that the first technology provides substantially lower waste of manganese (about by a factor of two) than the second one, which is highly important to produce solders with strongly controllable additives. It is shown that, as the treatment time of mechanically alloying materials increases, their temperature properties correspond to alloys obtained by direct alloying the components. The proposed method seems to be promising for production of relatively small amounts of alloys of components which differ in density, melting point, volatility, interaction with gases, and other physical-mechanical properties. 相似文献

Wire-Based Friction Stir Processing as a Novel Pathway for Solid-State Surface Alloying of Magnesium
Sabzevar M. Zahiri Mousavizade S. M. Pouranvari M. 《Metallurgical and Materials Transactions A》2021,52(11):4737-4741
Wire-based friction stir processing is introduced as a solid-state surface alloying strategy for surface alloying of AZ31 magnesium alloy with aluminum, as a key alloying element in magnesium alloys. This technique enables the formation of a defect-free, grain refined and alloyed surface with the increased volume fraction of Mg-Al second phase, and thus, enhanced surface hardness. This simple technique provides a solid-state surface alloying pathway to improve the surface properties of the metallic materials.
