Duplex stainless steels (DSS) suffer from thermal aging embrittlement after long-term service
in the temperature range of 280-320° C, leading to severe deterioration of mechanical …

The δ-ferrite decomposition has been widely reported in conventional Fe-Cr-Ni austenitic
stainless steel during thermal aging. However, a novel phenomenon is found in a Si …

Precipitates play significant roles in materials design but in-depth understanding of the
evolution of nano-scale precipitates in complex martensitic steels is still limited. In this study …

A spinodal decomposition is often carried out in the austenite-ferrite duplex stainless steel
Fe20Cr9Ni during long-term service at a temperature in the range from 280 to 320° C …

The poor machinability and extensive work hardening of Ni-based superalloys makes
additive manufacturing an attractive option for producing geometrically complex components …

Abstract Mn-Ni-Si intermetallic precipitates (MNSPs) that are observed in some Fe-based
alloys following thermal aging and irradiation are of considerable scientific and technical …

Precipitation hardening is one of the most important strengthening mechanisms in metallic
materials, and thus, controlling precipitation is often critical in optimizing mechanical …

Si-modified A286 alloy was designed to be compatible with liquid lead-bismuth eutectic
(LBE) metal. The addition of Si resulted in a distinct microstructure compared to A286 alloy …

Ultra-high strength steels are interesting materials for light-weighting applications in the
transportation industries. A key requirement of these applications is weldability and …

A series of G-phase strengthened ferritic stainless steels Fe-20Cr-3Ni-3Si-X (X= 2Mn, 1Mn-
2Ti, 1Mn-2Nb and 1Mn-2Ta) are characterized after aging using experimental …
