| The conventional powder metallurgy (powder mixing, compacting and sintering) allows to obtain a wide variety of shapes and sizes at low production costs [1]. However, incorrect ductility and low understanding of deformation mechanism of several nanocrystalline metal alloys is still a problem in the field of high-strength materials application. Mechanical alloying is a solid-state powder processing technique useful to produce nanocrystalline materials. The conventional powder metallurgy can be modified by an additional step: mechanical alloying/mechanical milling; being possible to obtain materials with enhanced properties. In addition, milled powders present higher chemical homogeneity than casting. The microstructure obtained by the compaction and sintering route is typically porous and may damage the physical and mechanical properties of final products. The NiCo systems possess high ductility and are commonly used in applications that toughness, strength and wear resistance are required [2]. The aim of this work is to evaluate the microstructure and hardness of bulk specimens from mechanically alloyed NiCo powders produced by two different routes: sintering and electric arc melting. | |
