Polished surfaces of Ti-6Al-4V, the most commonly used titanium alloy, were observed to suffer from hydride growth and associated embrittlement during hydrogen charging, whereas rough suffered no such susceptibility. Direct microscopic analyses recombined bubbles thermal desorption spectroscopy (TDS) revealed that surface roughening promotes recombination atomic molecular hydrogen, in turn, red...

Dense Pd membranes are receiving significant attention for hydrogen separation in advanced coal-conversion processes because of their high hydrogen permeability and their nearinfinite selectivity. However, pure Pd is susceptible to hydrogen embrittlement as a result of the expansion of the Pd lattice during β-Pd-hydride formation. Furthermore, H2S, a coal gasification byproduct, severely inhibi...

Hydrogen plays a vital role in the utilisation of renewable energy, but ingress and diffusion hydrogen gas turbine can induce embrittlement on its metallic components. This paper aims to investigate transport non-hydride forming alloy such as Alloy 690 used turbines inspired by service conditions blades, i.e. under combined effects stress temperature. An appropriate equation is formulated, acco...
