Phase Diagrams of Fe-Si Alloys under High Pressures
Introduction Iron is the most abundant element in the Earth’s core. However, the density of the outer core is about 10% lower than the density of iron at the pressure and temperature conditions of the outer core, indicating the presence of a low-atomic-weight component (such as H, C, O, Si, or S) in the core [1]. There is also evidence that the inner core may be less dense than pure iron and th...
متن کاملبررسی خواص سایشی آلیاژهای Al-(5-13)Si-Fe
در این تحقیق تاثیر آهن (wt%2-2/0) بر خواص سایشی آلیاژهای Al-(5-13)Si مورد بررسی قرار گرفته است. آزمایشهای سایش در دمای محیط، بار N45، سرعت m/s13/0 و مسافت m1000 به روش پین روی دیسک انجام شدند. بر اساس نتایج به دست آمده، در غلظتهای آهن کمتر از غلظت بحرانی (wt%2/1 در این تحقیق)، افزایش سیلیسیم موجب شکلگیری صفحات ظربف AlFeSi در نواحی بین دندریتی شده و بواسطه افزایش سختی زمینه و کاهش سیلان پلاست...
متن کاملThe influence of microchemistry on the recrystallization texture of cold-rolled Al-Mn-Fe-Si alloys
The recrystallization textures of a cold-rolled Al-Mn-Fe-Si model alloy with three different microchemistry states after non-isothermal annealing were studied. The microstructure and texture evolution have been characterized by EBSD. It is clearly demonstrated that the actual microchemistry state as determined by the homogenization procedure strongly influence the recrystallized grain size and ...
متن کاملSoft Magnetic Properties of High-Entropy Fe-Co-Ni-Cr-Al-Si Thin Films
Soft magnetic properties of Fe-Co-Ni-Al-Cr-Si thin films were studied. As-deposited Fe-Co-Ni-Al-Cr-Si nano-grained thin films showing no magnetic anisotropy were subjected to field-annealing at different temperatures to induce magnetic anisotropy. Optimized magnetic and electrical properties of Fe-Co-Ni-Al-Cr-Si films annealed at 200 ◦C are saturation magnetization 9.13 × 105 A/m, coercivity 79...
متن کاملNucleation mechanism of nano-sized NaZn13-type and α-(Fe,Si) phases in La-Fe-Si alloys during rapid solidification
The nucleation mechanism involving rapid solidification of undercooled La-Fe-Si melts has been studied experimentally and theoretically. The classical nucleation theory-based simulations show a competitive nucleation process between the α-(Fe,Si) phase (size approximately 10 to 30 nm) and the cubic NaZn13-type phase (hereinafter 1:13 phase, size approximately 200 to 400 nm) during rapid solidif...
