The extrusion with different powder consolidation methods, which is based on the superplastic behavior of the Zn-22wt%Al alloy powder, is proposed to observe the microstructure of helical gears and extrudability. The specifications of the helical gears were as follows: m, 0.3; Z, 12; Dp, 3.727mm; and β, 15˚. Compacted powders were consolidated by solution treatment, dwelling & quenching and sintering. The consolidated billets consisted of equiaxed fine grained structure, lamellar structure and mixed phase. Extrusion experiments were carried out under the following conditions: temperature, 250˚C and extrusion velocity, 0.1mm/min. The mechanical properties of extruded helical gears were investigated by measurement of Vickers hardness, extrusion load and SEM observation.
