The interaction between the surface of stainless steel and Bacillus cereus was studied in terms of the characteristics of interfacial interaction determined from the measurement of the contact angle of the surface of B. cereus and stainless steel in the presence or absence of B. cereus adherence. The microtopographies and the roughness of the surface of stainless steel and stainless steel adher...

Article history: Received 29.05.2012. Received in revised form 27.07.2012 Accepted 03.09.2012. The influence of sub-temperature quenching temperature on the tensile strength, hardness and toughness of 60Si2Mn steel has been studied, and the ferrite content, austenite grain size and martensite morphology of the microstructure of this steel after sub-temperature quenching analyzed. The results sh...

Radiation damage will be a major key point in the design of the many duplex components in fusion reactors. There is a substantial amount of available data showing that stress plays a major role in the onset, and possibly the rate, of void growth in austenitic stainless steels. There is also a strong support for models which predict a coupling of swelling and creep through the stress environment...

Abstract Duplex stainless steel has been widely applied to industry. In this paper, nondestructive testing, chemical composition analysis, metallographic hardness test, and scanning electron microscope were used study the causes of crack in butt joint girth weld pipe flange. Both flange are duplex S31803. Through it was judged that a crystalline crack, generated welding process, which related p...
