Abstract:
The fast-wearing parts of machinery and equipment of the processing branch of the agro-industrial complex are made of corrosion-resistant steels of various classes. There are many ways to restore them, but the most optimal way is electrocontact welding of corrosion-resistant steels of the appropriate class. This method has a number of advantages over other recovery methods, however, the effect of electrocontact welding of the tape on the corrosion resistance of the coating has not been practically studied. (Research purpose) The research purpose is theoretically substantiating the possible rea

Abstract:
Structural and chemical attributes of amorphous and nanocrystalline metals, which affect their corrosion behaviour are outlined. Effects of the fraction of intercrystalline regions, diffusivity, chemical homogeneity / heterogeneity and local ordering are indicated. These features can lead to higher or lower corrosion resistance as compared to coarse-grained counterparts, depending on the nature of tested metal and corrosive environment. Contributions of these factors are represented by two examples of passive behavior of nanocrystalline metals and amorphous Ni-P alloys.

Abstract:
A solid-phase diffusion welding of coarse-grained and ultrafine-grained (UFG) specimens of titanium near-α alloy Ti-5Al-2V used in nuclear power engineering was made by Spark Plasma Sintering. The failure of the welded specimens in the conditions of hot salt corrosion and electrochemical corrosion was shown to have a preferentially intercrystalline character. In the case of the presence of macrodefects, crevice corrosion of the welded joints was observed. The resistance of the alloys against the intercrystalline corrosion was found to be determined by the concentration of vanadium at the titan

Corroded behavior of 310S stainless steel by molten Al-Si eutectic alloy in high temperature thermal cycles of 495~620°C was investigated. SEM/EDX, XRD and metallographic technique were used for observing and analyzing the morphology, composition and internal microstructure of the corrosion specimens. Results showed: on the surface of 310S stainless steel, after corroded through 300 melting-solidification thermal cycles, a corrosion layer of about 3μm thick, composed mainly of Fe2Al5 phase and FeAl3 phase was formed. Besides, upon observation of internal microstructure of 310S stainless steel

Abstract:
Refractory iridium has a unique position among metals due to its resistance to corrosion and its inclination to brittle fracture, the latter only occurring under tension. Since 1960 iridium has been the subject of much research, but this has not lead to an understanding of its inclination to brittle fracture under load, although the problem of working iridium has been successfully solved. Grain boundary brittleness during mechanical treatment is the main problem with iridium, and is a continuing and important topic for academic discussion about iridium. Discussion of this problem, begun forty

Abstract The article will be focused on examining and comparing the influence of structure, sensitization and corrosion on the fatigue properties of austenitic stainless steel. The methodology of the experiment includes fatigue tests of samples attacked by intercrystalline corrosion. Therefore, the test samples were subjected to heat treatment for sensitization. Then these samples were subjected to long-term exposure in an aggressive corrosion solution. Experiments deal with microstructural material analysis, fractographic analysis, mechanical and fatigue tests.

The fracture surfaces were intercrystalline in appearance with the fractures occurring along the dendritic grains of the weld metal. The cracking is considered to be an intercrystalline stress corrosion cracking phenomenon of susceptible Alloy 182 weld metal in a boiling

Abstract Wrought Ni-Cr-Mo alloys of the C-family show a sensitivity to intercrystalline attack especially after exposure in the temperature range of 650°C to 950°C. Nevertheless, microstructural changes due to precipitation of intermetallic phases can occur up to a temperature level of 1050°C and this can affect the localized corrosion resistance. Thermal stability of wrought Alloy C-276 is a lot lower in comparison to Alloy 59. Sensitized at 870°C for only 1 hour, Alloy C-276 fails in the ASTM-G 28 B test due to rapid intercrystalline penetration and pitting whereas Alloy 59 can be aged up to

Abstract:
Abstract Before the introduction of welded boiler designs, many catastrophic boiler failures were caused by intergranular corrosion (caustic embrittlement) of riveted seams, rolled tube ends, and header tube ligaments. Although use of welded drums eliminated riveted seams, rolled tube ends and tube ligaments still may be subject to intercrystalline cracking. This paper will review research that explored caustic embrittlement causes, contributing factors, diagnostic procedures, and corrective methods.

Abstract Alloy 625 is frequently used as reactor material for Supercritical Water Oxidation (SCWO) applications. This is due to the favorable combination of mechanical properties, corrosion resistance, price and availability. Nevertheless, the corrosion of alloy 625 like the corrosion of other Ni-base alloys during oxidation of hazardous organic waste containing chloride proceeds too fast and is a major problem in SCWO applications. In these experiments high pressure, high-temperature resistant tube reactors made of alloy 625 were used as specimens. They were exposed to SCWO conditions, withou

Alloy UNS N08031 exhibits good resistance to pitting and crevice corrosion in neutral and acid aqueous solutions, which makes it advantageous to the known 6 % Mo stainless steels, and even several nickel alloys.
