Special Issue Information

Dear Colleagues,

The rising demand for energy and climate change crisis bring many challenges in design and manufacturing of advanced metals and alloys for electric power generation, oil/gas transportation, and hydrogen storage. Development and application of high-performance alloys remains a slow process due to a limited understanding of their mechanical degradation behaviours (i.e. creep, creep-fatigue, low fracture toughness, hydrogen embrittlement) under harsh environments (i.e. elevated temperature, low temperature, corrosive). Many advanced manufacturing technologies, including novel thermomechanical processing and additive manufacturing, have been developed and applied for improving mechanical properties and fabricating new components in multiple scales. However, highly deformed and non-uniform constituents, and rapidly solidified microstructures are usually produced by these processes. This further results in sub-optimal properties and premature failure under certain conditions. The full picture of the interactions between heterogeneous microstructure and complex mechanical conditions, and harsh service environments is still not complete and needs more fundamental studies.

I would like to invite you to submit your excellent research works to this Special Issue on “Mechanical Degradation of Advanced Energy-related Alloys: Processing, Microstructure, and Testing” in Crystals. This Special Issue of Crystals will primarily focus on gaining a deeper understanding of mechanical degradation mechanism of advanced energy-related alloys under harsh environments. Both experimental and modelling contributions as full-length research articles, short communications, and reviews are very welcome. The potential topics include, but not limited to the fields indicated in the keywords below.

Haynes 282 has attracted attention for casting applications in AUSC power plants due to its good creep properties. However, the market is primarily comprised of wrought Haynes 282, while the cast version is not commercially available. In this study, the microstructure of a large traditional sand cast Haynes 282 was studied from as-cast condition to long-term heat-treated condition by combining experimental data and thermodynamic calculations. The microstructure of a large cast Haynes 282 includes γ, γ’, two types of MX, M23C6 and µ phases. After standard post heat treatment, µ phases were dissolved and precipitated as M6C. The equilibrium state was achieved after 266 h aging at 788 °C, after which γ’ particles began coarsening. These kept to a spherical morphology; the smallest misfit was found with the γ matrix. Once post heat treatment was finished, MX exhibited little morphology and compositional change during the long-term isothermal aging. Grain boundary is covered by discrete M23C6 and M6C precipitates and this morphology keeps stable during isothermal aging. No presence of the needle µ phase have been found at grain boundaries after 10,000 h aging at 788 °C. All these microstructural features indicated that cast Haynes 282 could have a high thermal stability and good creep properties. Full article
