In this study, a cast rod is used as the material for the forging process (without extrusion). The cast forging process is used to ameliorate the coarse grains that form in the follow-up heating process of extrusion-forged materials. Infrared (IR) heating is also used for comparison with conventional heating processes. Experimental results show that the direct forging process (without extrusion) suppress coarse grain formation and that IR heating can improve the mechanical properties of cast- and extrusion-forged materials. IR heating also enhances the tensile properties of forged materials.
