Summary: The pitting corrosion susceptibility of 904L stainless steel in aerated LiBr solutions was studied using electrochemical measurements. The experimental variables, including electrolyte concentrations, pH, scan rate, temperature, and constant potential, were investigated. The results showed that the uniform corrosion rate and pitting corrosion susceptibility increased with increasing LiBr concentrations and temperature. Increasing the pH of the solution decreased both corrosion rates. An increase in scan rate enhanced uniform corrosion but suppressed pitting corrosion. EIS diagrams displayed a depressed semicircles with the center under the real axis. Bode plots supported the result that the uniform corrosion resistance decreased with increasing Br- anion concentration in LiBr solutions. The observations suggested that the observed single time constant may actually be the overlap of two time constants.

Summary: The influences of laser shock peening (LSP) with different coverage layers on the electrochemical and long-term immersion corrosion behaviors of 2Cr12NiMoWV martensitic stainless steel in 3.5 wt% NaCl solution were studied. LSP-induced corrosion resistant surface resulted in significant diminution of corrosion density and passive current density, as well as higher pitting potential. LSP-generated carbide decomposition, matrix nanocrystallization and surface segregation of Cr contributed to the generation of Cr-rich passive film with better corrosion resistance. Due to the inhibitory effect of matrix nanocrystallization and compressive residual stress on corrosion propagation, LSP greatly reduced the size and number of the corrosion pits even after 30 days' immersion in NaCl solution.

Summary: The effect of ferrite morphology on the pitting corrosion resistance of austenitic stainless steel weld metals was studied. Pitting corrosion mainly occurred at the ferrite/austenite interface, especially at the vermicular ferrite/austenite interface. However, less pitting corrosion was observed at the lacy ferrite/austenite interface due to the establishment of a Kurdjumov-Sachs orientation relationship, which resulted in lower precipitation of Cr carbide and reduced likelihood of pitting corrosion initiation.

Summary: The effects of laser shock peening (LSP) on the electrochemical and long-term immersion corrosion behaviors of AISI 420 martensitic stainless steel in a 3.5 wt% NaCl solution were studied. The results showed that LSP treatment significantly improved the corrosion resistance of the steel, with a decrease in passive current density and an increase in pitting potential. The LSP treatment also resulted in the formation of a Cr-rich passive film with better corrosion resistance, and the inhibitory effects of nanocrystalline structure and compressive residual stress effectively prevented rust formation even after 30 days of immersion.

Summary: This study investigated the leakage failure of a 304 stainless steel spiral plate condenser. Through cutting and opening the condenser, leakage points were found near the welding joints between the spacing columns and stainless steel spiral plates. The leakage of the condenser was caused by pitting corrosion, likely due to chloride ions near the welding joints, and worsened by the sensitization of stainless steel in the welding zone.

Summary: This study proposes the use of Scanning Electrochemical Cell Microscopy (SECCM) to collect corrosion activity from random locations on 316 L SS. Pitting corrosion was triggered by potentiodynamic polarization tests in the presence of chloride. Data science methods were employed to analyze 955 j Vs E curves and understand the conditional log(j) distributions at different potentials. The study found that the log(j) distribution was potential-dependent and became more random with increasing testing aggressiveness.

Summary: The long-term corrosion behavior of 2205 duplex stainless steel was investigated in hot concentrated artificial seawater under intermittent vacuum boiling conditions. Compared to the atmosphere state, the passive film on the specimen surface is thinner and the induction time for pitting corrosion decreases notably. However, the lower dissolved oxygen content and violent boiling of the solution retard the pit propagation.

Summary: This study investigated the acoustic emission behavior of a single pit evolution on two types of stainless steels using small-scaled electrodes, finding that there were dozens of AE signals observed during pitting on 17-4 PH, but much less acoustically emissive on 304 SS. In-situ optical observation revealed black flocculent clusters in 17-4 PH during pitting, while this process was weak in 304 SS. It was concluded that the formation of hydrogen bubble inside the pit and the perturbation of electrolyte around the pit created AE signals.

Summary: The effects of microstructural evolution on the semiconducting properties and pitting behavior of 304 stainless steel were investigated using electrochemical measurement. It was found that grain coarsening reduced the corrosion resistance of 304 SS in coal chemical high salty wastewater due to the increased formation of defects in the passive film caused by a larger fraction of high-angle grain boundaries. The higher donor density on the specimen's surface also led to a deterioration of passive film stability. Additionally, grain coarsening resulted in an increase in the lifetime, growth rate, and peak current of metastable pits, as well as a gradual increase in the width-depth ratio of stable pits and changes in their shape.

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.

Summary: This study investigates the fatigue behavior of concrete under different stress reversal conditions. The results indicate that stress reversal generally causes more severe damage and reduces the cycles to failure compared to tensile fatigue. Additionally, adding some level of compression contributes to the energy required for failure under stress reversal fatigue. Specimens with higher concentration of fractured aggregates achieve longer fatigue lives.

Summary: The susceptibility of building stones to fire and high temperature was investigated in this study by examining their physical and mechanical properties. The results show that both compressive and tensile properties of stones are affected by temperature changes. The tensile strength is particularly sensitive to temperature changes, requiring special attention to the components subjected to tensile stress in stone buildings. Principal component analysis was used to predict the mechanical properties of stones, providing a new method for calculating the residual mechanical properties after high temperature or fire.
