“…In the last two decades the main efforts have been focused on Cu or Al systems, with body centred cubic (bcc) second phase such as Nb or Ta, i.e., CuX (where X = Nb, Ta, Cr, V or Fe), 28) having the objective of increasing the mechanical strength of these alloys. In the 1990's, some studies started with hexagonal (hcp) metals including TiY, 9,10) MgTi, 11) AlTi 12) and Al Mg, 13) however, the understanding of the fundamental mechanisms controlling the mechanical deformation and the microstructure evolution is still unclear.…”
