Size And Morphology

In powder metallurgy (PM), severe plastic deformation (SPD) is a well-known technological solution to achieve interesting properties. However, the occurrence of pores in the final product may limit these properties. Also, for a given type of microstructure, the stereometric parameters of the pore structures, such as shape (represented by Aspect and Dcircle) and distribution (fshape, and fcircle), decisively affect the final properties. The influence of different processing routes (pressing, sintering and equal channel angular pressing (ECAP)) on pore structures in an aluminum PM alloy is discussed. The nature of porosity, porosity evolution and its behavior is explored. The correlation between pore size and morphology is also considered. The final pore structure parameters (Aspect, Dcircle, fshape, and fcircle) of studied aluminum alloys produced by different processing routes depends on the different formation routes.

Metallurgy Process

Large extrusion and forgings of Al-9Fe-1.9Mo-1.7Si (wt.%, FMS0918) aluminum alloy for elevated temperature applications were produced by rapidly solidified powder metallurgy process. Powders of FMS0918 alloy were produced by inert gas atomization, and then screened, canned, degassed, extruded and forged. The extrusion exhibited good strengths and elongation in longitudinal orientation, but low elongation in long- and short-transverse orientations. After forged, the tensile strengths of the forgings showed little change, but the long- and short-transverse elongation was improved.
