متن کاملHIGH TEMPERATURE TENSILE PROPERTIES OF NEW FE-CR-MN DEVELOPED STEEL
Nowadays, Ni-free austenitic stainless steels are being developed rapidly and high price of nickel is one of the most important motivations for this development. At present research a new FeCrMn steel was designed and produced based on Fe-Cr-Mn-C system. Comparative studies on microstructure and high temperature mechanical properties of new steel and AISI 316 steel were done. The results ...

15 صفحه اولResearch on Cold Crack Sensitivity of High- Strength Wear-resistant Steel Nm360 after Welding
Article history: Received: 21.04.2014. Received in revised form: 02.07.2014. Accepted: 14.07.2014. Due to the high amount of carbon and diffusible hydrogen, high-strength wear-resistant steel NM360, which is widely used on excavating machinery, always tends to develop cold crack after welding. Heat affected zone (HAZ) is the weakest part in a welding joint and is the most probable location for ...
متن کاملNumerical Simulation of High Temperature Corrosion Processes in Mn, Cr, Si, Al – Alloyed Steel Samples
The grain boundary oxidation mechanism in hot rolled steel samples during cooling from 500 °C – 800 °C down to room temperature was mathematically modeled. Given a fixed temperature ramp, the migration of the atomic species (iron, oxygen and the alloying elements) has been calculated with the parabolic rate equation for diffusion. After each small time step, the data was transferred into the da...
