Tailoring heat-resistant phases with strengthening effects by compound additions of zirconium, yttrium and silicon in dilute Al-Sc-(Zr)-(Y)-(Si) alloys

Tailoring heat-resistant phases with strengthening effects by compound additions of zirconium, yttrium and silicon in dilute Al-Sc-(Zr)-(Y)-(Si) alloys

Heat resistance aluminum alloys serving within 300–400 °C temperature range are prominently required due to lightweight design and extreme serve condition in aerospace and military fields. Dispersoid particles precipitated in Al–Sc system alloys possess preferential thermal stability, however, unsat...
