Production and Characterization of Stainless Steel Based Fe-Cr-Ni-Mn-Si(-CO) Shape Memory Alloys
It is well known that the Fe based alloys can exhibit shape memory effect due to the y to E martensitic transformation. The effect may not be as striking as observed in the NiTi alloy but it might become attractive fkom the practical point of view. In this work, two compositions of Fe-Cr-Ni-Mn-Si(-Co) stainless steel based shape memory alloy, prepared by the VIM technique, will be presented. Th...
متن کاملThe Effect of Mn-Depleted Surface Layer on the Corrosion Resistance of Shape Memory Fe-Mn-Si-Cr Alloys
In this work, we have examined Fe-Mn-Si-Cr alloys possessing a good shape memory effect due to a high Mn content (28 wt pct). The addition of Cr (5 wt pct) was made in order to give fairly good corrosion resistance to the alloy. But we have verified that even in moderately corrosive environments, the presence of chromium does not bear any passivation. On the other hand, we have found that the a...
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...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
