Currently, blood pressure assessment is on the verge of shifting from classical cuff-based measurements to continuous estimation using smart devices based on the absorption and reflection characteristics of light in tissue. This type of blood pressur

Hydrogen environment embrittlement (HEE) of low-nickel austenitic stainless steels (AISI 300 series) with different chemical compositions was studied focusing on the impact of the steels surface oxides, grain sizes and dislocation arrangements. The s

Hydrogen embrittlement (HE) of several low-nickel austenitic stainless steels (AISI 300 series) was studied with special attention to the impact of strain induced α′-martensite. The susceptibility of the steels to HE is judged with respect to the

Purified iron was loaded electrochemically with hydrogen in the presence of a hydrogen promoter, leading to the formation of cracks inside of the bulk and blisters on the surface. The mechanism for the crack initiation was investigated using SEM cros

Steel powders obtained by mechanical alloying of iron and graphite were compacted by high-pressure torsion. During high-pressure torsion, mean grain sizes rise from about 10 nm after mechanical alloying to about 20 nm. Vickers hardness reaches values

The effect of dissolved hydrogen on the dislocation density in cold-rolled palladium was investigated in order to provide evidence of a line energy reduction caused by hydrogen–dislocation interaction as proposed by the defactant concept. For this

In cold-rolled Pd and Pd–H alloys the presence of hydrogen enhances the multiplication of dislocations and leads to an increase in dislocation density as compared to pure Pd. Subsequent removal of H from Pd–H alloys does not influence the disloca

The effect of dissolved hydrogen in a (1 0 0) vanadium single crystal was studied using compression tests of micropillars. It is observed that the shape of the deformed pillars changes with hydrogen concentration. At low concentrations the pillars de

Cold-drawn pearlitic steel wires were subjected to differential scanning calorimetry and resistivity measurements during heating. Both techniques yield two peaks, one at 500–600 K, the other at 400–450 K. Whereas the peak at 500–600 K can be as

Cold-drawn pearlitic steel wires are known to exhibit increasing strength with increasing elongation and are therefore highly interesting for a wide field of engineering applications. When isochronal heat treatment is performed at different temperatu
