Heat-resistant materials, applied to manufacturing high-temperature components, are pivotal for raising the steam temperature parameters of advanced ultra-supercritical power plants. Alumina-forming austenitic (AFA) stainless steel, a promising candidate material applied to manufacture high-temperature components in fossil-fired ultra-supercritical steam plants, has been concerned by researchers. In this review, the recent progress of AFA steels with considerations of precipitations, high-temperature creep properties, and oxidation resistance was summarized. The stability of precipitates at hi...

What is Nickel-Copper?Nickel-Copper (Ni-Cu) alloys exhibit simultaneously high strength and toughness, excellent corrosion resistance, and may show good wear resistance. The Ni-Cu system forms the basis for the Monel alloy family. Monel was discovered by Robert Crooks Stanley who was employed by the International Nickel Company (INCO) in 1901. The new alloy was named in honour of the company president, Ambrose Monell. Ni and Cu exhibit very similar atomic characteristics. They both have face cen

This article discusses the impact of heat treatment on the development of the microstructure and corrosion resistance of weldments made of 2205 duplex stainless steel (DSS). It also provides an overview of the properties and applications of DSS.
