This research evaluated the kinetics of δ-phase growth in laser powder bed additively-manufactured (AM) Inconel 625 during post-build stress-relief heat treatments. The temperatures ranged between 650 °C and 1050 °C, and the times from 0.25 to 168

The microstructural evolution of laser powder-bed additively manufactured Inconel 625 during a post-build stress-relief anneal of 1 hour at 1143 K (870 °C) is investigated. It is found that this industry-recommended heat treatment promotes the forma

The creep behavior of a monocrystalline Co-based γ − γ ′ superalloy (Co–28.8Ni–6.2Al–1.8Ti–2.0W–2.7Mo–1.8Nb–0.9Ta, at%) is investigated for two types of rafted γ′-phase: (i) rods parallel (p-type) and (ii) plates perpendicular

A ternary Al-6.9Ce-9.3Mg (wt.%) hypoeutectic alloy, consisting of equal amounts of α-Al(Mg) solid-solution regions and Al(Mg)-Al11Ce3 eutectic colonies, is investigated in terms of its aging and creep resistance. The eutectic regions exhibit a micro

Nickel- and cobalt-based superalloys derive their excellent oxidation and corrosion resistance from the surface oxidation of Al and Cr, which form protective oxide layers. Starting from an existing Cr-free cobalt-based superalloy (Co–30Ni–7Al–4
