The effects of impurity ions, dissolved oxygen, applied potential and temperature onstress corrosion cracking (SCC) of engineering materials used in nuclear power plants, including304 stainless steel (SS), 316 SS and A533B pressure vessel steel, in high t

Now corrosion is still a troublesome problem in chemical industry in China. Basedon the experience of the author, this subject is reviewed and discussed in terms of total corrosioncontrol, non-metal materials and equipment, corrosion in biger plant and th

The main new viewpoints in the mechanism of stress corrosion cracking proposedin the last decade were reviewed. Based on the recent work on the mechanism of stress corrosioncracking of the authors, the new results in disolution facilitating dislocation em

In this paper, the definition, experimental procedure, characteristics, enhancementmechanism of surface enhanced Raman spectroscopy and its applications in chemistry are reviewed.

Process of creep and fracture of six types of superalloys which include wrought,conventional casting, directional solidification and single--crystal, in hot corrosion environmentswere studied. The fracture performane of alloys were discussed in terms of t

The holographic microphotography (HM) was coupled with electrochemicalmeasurement to investigate the changes of the electrode-electrolyte interface during the processesof iron anodic dissolution, potentiostatic current oscillations, passivation, depassiva

Some designing principles concerning the composition and microstructure of corrosive wear resistant alloys have fully been discussed in present paper. The effects of strainhardening, secondary phase strengthening, heat treatment as well as proteciveness o

The oxidation of two Co-Nb alloys containing 15 and 30 wt% Nb has been studiedat 600-800℃ in H2-CO2 mixtures providing an oxygen pressure of 10-24 atm at 600-800℃and of10-20 atm at 700 and 80℃, below the dissociation pressure of cobalt oxide. At 600 and 7

The effect of hydrogen on the strain distribution at crack tip and the relative crackopening displacement has been studied in situ by the laser speckle interferometery (SPI) forsingle-edge notched plate specimens of A537 steel under the condition of 6h hy

The effect of chemical composition and heat treatment on intergranular corrosion(IG) and stress corrosion cracking (SCC) behavior of Inconel-690 alloy was investigated. The results showed that the iG resistance obviously decreased with increasing the C an

Hydrogen permeabilities and diffusivities in # 10 carbon steel coated with Pd andpre-oxidized were determined using the gaseous permeation technique over the temperature rangeof 80 to 330℃. For temperature below 150℃, oxide scale had a marked barrier effe

Anodic dissolution (AD) and hydrogen formation occur simultaneously at corrosionfatigue (CF) crack tip. The AD of material increases the plastioc zone size at CF crack tip, whilethe entrance of hydrogen into material decreases size of the plastic zone at

Based on the principle of corrosion electrochemistry, a new design of corrosion current measurment meter has successfully been realized. with this new instrument,the theoreticalparameter B which concerns the Icorr deeply can be obtained directly,and calcu

TiN films were deposited on to SUS304 stainless steel by an ion plating process using hollow cathode discharge (HCD). The crevice corroison resiseance of the TiN coated steel insea water was studied by the electrochemical method. The results indicated tha

Anticorrosion of NaNO2 on reinforced steel inside concrete containing anti freezing mixture have been studied by means of electrochemical measurment and static immersion inseawater. It was observed that pittings occur on reinforcement under the experiment

In this paper the corrosion behavior of 20# boiler steel, a kind of low-carbon steelwidely used in petro-chemical industry, is studied in dilute industrial solution containingpropylene carbonate by electrochemical method. It is found that the corrosion re

The rear axle housing of 8 home made heavy tip'tracks, type K29 was cracked inHuangdao, which was only used for 9-12 Mon.The reason of the failure of the rear axle housingwas the result of corrosion fatigue. neither stress corrosion cracking nor mechanic
