چکیده
Accumulative roll bonding (ARB) is one of the severe plastic deformation processes that is used nowadays to produce metal matrix composites (MMCs) extensively. In this paper Al/Al2O3/TiC hybrid composite was produced using ARB and anodizing processes. The aim of the present work is to produce high strength Al/Al2O3/TiC hybrid composite with a different volume fraction of alumina and titanium carbide uniformly dispersed in aluminum matrix using the above processes. Alumina layer with different thickness was achieved with anodizing of aluminum at different times. Microstructure observations showed that by increasing the number of rolling cycles, distribution of reinforcement particles (Al2O3, TiC) in aluminum matrix became more uniform. Mechanical properties of hybrid composite were evaluated at different passes of ARB process. As strain was increased (with increasing the number of passes), mechanical properties of produced composite such as tensile strength were increased consequently. But ductility at first was decreased and then increased. It can also be seen that by increasing quantity of alumina and titanium carbide, tensile strength is improved.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
