On the Development of Dual Graphite Iron as a Functionally Graded Material
Graphite morphology plays significant roles in mechanical properties in graphitic cast irons. Typically, cast irons are made with uniform graphite morphology and distribution across the microstructure of castings.
Identification of carbides and phase transformations in sintered Fe–Mo–Mn–C alloys produced under a slow continuous cooling
Different sintered alloys were produced by sintering and slow cooling of powder compacts made from pre-alloyed Fe-0.50 Mo-0.15 Mn powder mixed with varied graphite powder contents (0.30–1.20 wt.% with 0.15% increment).
Ferrite and Carbide Mixtures in Sintered Hyper-Eutectoid Fe-xMo-0.90 C Alloys
Phase transformations in low- to medium-carbon Fe-Mo-C alloys have been widely investigated for decades and fruitful information regarding phase transformation is available. However, hyper-eutectoid Fe-Mo-C alloys were least studied.
Effect of carbon content on microstructure and mechanical properties of sintered Fe-Mo-Mn-C alloys
Sintered Fe-Mo-Mn-C alloys were produced by sintering of mixtures of pre-alloyed Fe-0.5 Mo-0.15 Mn powder and varied carbon amounts (0.30-1.20 wt.% with 0.15% increments) followed by slow cooling in furnace.
