Surface Cracks in TP2 Copper Tube Billets in Horizontal Continuous Casting;

An Analysis on Surface Cracks Formation of H Beam of Nb-V Microalloying Steel BS55C;

The surface flaws of different sizes were introduced into SiC/BN laminated ceramics by Vickers indentation method.

Analysis of reasons for surface cracks of 42CrMo spindle;

The cause of surface cracks of the propylene spherical tank was analyzed comprehensively.

Surface cracks have a very complicated stress state To give the safety of device with cracks is very difficult by normal method of stress analysis This article makes a crack adjudhement with the code of CVDA-84 to the surface cracks in the balled vessel which was inspected in 199

Influence of CO_2 partial pressure on the protection property of corrosion scale formed on N80 steel;

Stress corrosion performance of N80 steel in formation water;

Analyzing electrochemical behaviors of N80 steel under the conditions of high temperature and high pressure containing CO_2/H_2S.;

The results show that their CO_2/H_2S corrosion rates increase with increasing CO_2 partial pressure, and the corrosion rates of steel P110 are nearly always higher than that of steel N80 except when CO_2 partial pressure is very low.

The electrochemical impedance spectroscopy (EIS) was used to analyze the possible cathodic reactions and reaction rate during CO2 corrosion of steel N80 in various electrolytes.
