Aluminium crossover alloys are one of the more interesting recent developments in light metals. Rather than staying within the traditional wrought families, they deliberately blend the chemistries of the AA5xxx and AA7xxx systems, and in doing so they form the compositionally complex T-phase, Mg32(Al,Cu)49, which gives a remarkable hardening response and has already attracted serious … Continue reading On the 3D printing of novel aluminium crossover alloys
