Hydrogen embrittlement is a complex phenomenon, involving several length-and
timescales, that affects a large class of metals. It can significantly reduce the ductility and …

Fatigue is a dominant failure mechanism of several engineering components. One
technique for increasing the fatigue life is by inducing surface residual stress to inhibit crack …

Strong and ductile materials that have high resistance to corrosion and hydrogen
embrittlement are rare and yet essential for realizing safety-critical energy infrastructures …

Metals are key materials for modern manufacturing and infrastructures as well as transpot
and energy solutions owing to their strength and formability. These properties can severely …

High-entropy alloys have shown exceptional damage tolerance at cryogenic temperatures.
Here we report that this essential property can be maintained even when exposing the …

To understand the mechanism for hydrogen-induced embrittlement in a nickel-based
superalloy, detailed electronmicroscopy characterisation has been employed on the UNS …

Abstract Twin boundaries (TBs) in Ni-based superalloys are vulnerable sites for failure in
demanding environments, and a current lack of mechanistic understanding hampers the …

Uniaxial mechanical testing conducted at room temperature (RT) and 77 K on hydrogen (H)-
exposed nickel was coupled with targeted microscopy to evaluate the influence of …

In this study, the high cycle and very high cycle fatigue behavior of the GH4169 superalloy
was investigated. The results of the fatigue tests demonstrated that failures in the high cycle …

The strategy of heterogeneous-structured (HGS) high manganese steels was designed by
asymmetrical-rolling (AR) with annealing to obtain superior mechanical performance for …
