... ABSTRACT The effect of deformation-induced martensitic transformation on the cryogenic toughness of welds of austenitic stainless steel, which is a promising candidate material for large liquefied hydrogen storage tank materials, was investigated. From the results of microstructural...

... is preferred, its fatigue crack propagation characteristics are unclear, compounded by the extremely low temperature of liquefied hydrogen (-253°C), making martensitic transformation crucial. Understanding the relationship between crack growth rate and behavior aids in clarifying crack propagation, yet...

... transformation society diffraction journal ABSTRACT Though the majority of large-scale hydrogen storage tanks are made of metastable austenitic stainless steel in the world, its fracture properties remain unknown. Because the materials are under a complicated environment, exposed to hydrogen...

... that the temperature of the soil around the conduit changes most obviously after the liquid circulation begins, and the temperature rises rapidly. With the phase transformation of ice water in the soil, a large amount of heat is absorbed, so the temperature rise rate of the soil tends to be gentle. When all the ice...
