The technology of severe plastic deformation (SPD) is process on forming metals of large plastic strain used for mass production in order to make ultrafined-grained (UFG). There are several methods used in this SPD technology, namely multi-axial forging (MAF), equal channel angular pressing-parallel channel (ECAP-PC)/accumulative press bonding (APB) and repetitive press roll forming (RPRF), various methods are potentially applied in the industrial world because they are more effective and efficient compared to conventional methods. Through research on the characterization of aluminum-based composite materials with several SPD methods, the ideal variable will be obtained in producing high-strength materials. The development of a new SPD method driven by requirements simplifies the process, so that it can be applied to mass production, some of the development of SPD technology is able to produce high plastic strain. The market for nanostructured materials produced by SPD technology is in sectors where superior traits, such as specific strength or increased fatigue age, are needed by analysis of market application. Formal market analysis in nanostructured metals, carried out by Metallicum, has found more than 100 specific markets for nano metals in space, transportation, medical equipment, chemical processing, electronics, and defense. However, due to the still high operational costs, the application of nanotechnology is still limited to military equipment applications. This research is a comparison of several SPD methods (MAF, ECAP-PC/APB and RPRF) in the scope of advanced manufacture forming fabrication to utilize multi pressing applied to aluminum alloys and aluminum-based composites to produce material properties needed by armor material for defense equipment applications.
