Hydrogen interaction with Zr-based getter alloys in high vacuum conditions: In situ SIMS-TPD studies

I. I. Okseniuk et al.

Summary: This study summarizes the results of combined SIMS-TDS measurements on the interaction of hydrogen with various alloys at hydrogen pressures below 1 x 10(-2) Pa and temperatures ranging from 300 to 1100 K. The alloys showed varying levels of hydrogen absorption effectiveness and release temperatures, with different mechanisms such as chemisorption and bulk diffusion being involved. The comparative effectiveness of hydrogen absorption by the alloys followed the sequence Zr65V30Ti5 > Zr(V0.75Fe0.25)(2) > Zr2Fe.

Effect of the ferrite morphology on hydrogen embrittlement of MAG welded 304 austenitic stainless steel

Chilou Zhou et al.

Summary: This study investigates the relationship between ferrite morphology and hydrogen embrittlement (HE) in welded austenitic stainless steel. The results show that the morphology of ferrite influences the resistance to HE, with skeletal ferrite showing the highest resistance and lathy ferrite showing the lowest resistance.

Thermodynamics of spontaneous dissociation and dissociative adsorption of hydrogen molecules and hydrogen atom adsorption and absorption on steel under pipelining conditions

Yinghao Sun et al.

Summary: In this study, thermodynamic analyses were conducted to investigate hydrogen generation and adsorption on pipeline steels, revealing that dissociative adsorption is thermodynamically feasible over a wide range of temperature and pressure conditions, with increased hydrogen partial pressure and elevated temperature favoring the process. The stability of hydrogen adsorption differs at various sites on steel surfaces, with factors such as coverage, external pressure, and temperature influencing the process.

Electronic Structure of Molecules, Surfaces, and Molecules on Surfaces with the Local Modified Becke-Johnson Exchange-Correlation Potential

Tomas Rauch et al.

Summary: Understanding the electronic properties of matter is crucial for proposing useful applications, as accurate approximations to the exchange-correlation functional of density functional theory may become computationally expensive for modeling hybrid organic/inorganic systems. The study of the local modified Becke-Johnson exchange-correlation potential for calculated ionization potentials is important for band alignment in composite systems. Demonstrating the potential's application in the electronic structure calculation of a composite semiconductor/molecule system shows its accuracy and usefulness.

Hydrogen outgassing and permeation in stainless steel and its reduction for UHV applications

Samiran Mukherjee et al.

Summary: This article mainly discusses the application of stainless steel grades 304L and 316L in ultra-high vacuum systems in present-day research, highlighting the importance of selecting and operating large vacuum pumping systems and materials for vacuum system engineers. The challenges of hydrogen in structural steel and methods to reduce hydrogen outgassing rate in steel are also addressed as major concerns in current research.
