Study on Temper Embrittlement and Hydrogen Embrittlement of a Hydrogenation Reactor by Small Punch Test [PDF]
Materials, 2017 The study on temper embrittlement and hydrogen embrittlement of a test block from a 3Cr1Mo1/4V hydrogenation reactor after ten years of service was carried out by small punch test (SPT) at different temperatures. The SPT fracture energy Esp (derived from integrating the load-displacement curve) divided by the maximum load (Fm) of SPT was used to fit ...

Long-Term Embrittlement of Ancient Copper and Silver Alloys
Heritage, 2021 The manifestations of ancient metals’ embrittlement, cracking and fracture, are challenging problems for restorers and conservators, yet the scientific understanding of these problems is limited.

Workhardening behaviour and microstructural analysis of failed austenitic manganese steel crusher jaws [PDF]
Materials Research, 2013 This study focussed on the work hardening behaviour and microstructure of austenitic manganese steel relative to premature failure of crusher jaws. Samples of sound and failed crusher jaws were taken, the change with depth from the working surface to the

ANALYSIS OF Nb – Ni AND V – Ni BASED MEMBRANE CHARACTERISTICS
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2021 To obtain ultrapure hydrogen by membrane technology, instead of expensive membranes made of Pd alloys, cheaper ones based on metals (Nb-Ni) and (V-Ni) are considered.
