Long-term corrosion behavior of martensitic steel welds in static molten Pb–17Li alloy at 550°C

The Analysis of the Influence of Various Factors on the Development of Stress Corrosion Defects in the Main Gas Pipeline Walls in the Conditions of the European Part of the Russian Federation

“…The repair by replacing even a small part of these pipes will lead to a reduction in the total volume of UGSS pipeline overhaul due to the specific increase in the individual sections repair cost [10][11][12]. At the same time, the degree of defects' danger, the depth of which is less than 10-15% of the wall thickness, under condition that access of corrosive medium to them is restricted, is determined by many researchers as insignificant [13][14][15][16]. At the present time, there are methods of repairing the pipelines polymer insulation, which do not allow the cracks to develop and threaten the reliability of pipelines for a long time [17,18].…”

Hydrogen Storage Characteristics and Corrosion Behavior of V-rich Ti-V-Cr-Fe Alloy

“…Table 2 shows that both heat treatment processes increased the reversible hydrogen storage capacity (RHSC), the capacity increased from 0.44 to 1.26 wt% after annealing and to 1.26 wt% in quenched the sample. The literature indicates that annealing increases hydrogen capacity [13,14]. The BCC phase enhances hydrogen capacity [11,22,29]; increases in the unit cell volume implies the availability of more hydrogen absorption sites or spaces, leading to an increase in storage capacity.…”

“…A hydrogen desorption capacity of 2.3 wt% was achieved when Ti32Cr40V25 was annealed at 1653 K for 1 min. [13]. Chuang et al [14] found that annealing atomized powder of Ti-Zr based alloy at 1123 K for 4 h greatly enhanced the discharge capacity.…”

Mechanism-related modelling of pit evaluation in the CrNiMoV steel in simulated environment of low pressure nuclear steam turbine

“…Vignal et al [19] revealed that the secondary HAZ was the weak point of the stainless steel welded joint for which both the average pit density and the average pit surface area were significantly larger than those in other regions. Chen et al [20] concluded that the weld in the 9Cr based martensitic steels was one of the weakest sections to pitting corrosion. Sánchez-Tovar et al [21] reported that the susceptibility to pitting attack increased in the weld of LiBr as indicated by the large negative open circuit potential.…”
