Extrusion profiles are extensively used in industries and any improvement the process could potentially have a large impact on energy cost savings. In this study, novel extrusion method, namely multi-container extrusion, was proposed for producing thin-walled wide aluminium components with low force. Its basic principle is to enable multiple billets be welded forced through die orifice simultan...

Surface quality and dimensional precision will greatly affect parts during their useful life especially in cases where the components will be in direct contact with other elements during their application. This paper deals with three soft computing techniques namely Adaptive Neuro Fuzzy Inference System (ANFIS), Neural Networks (NN) and regression in predicting the surface roughness in turning ...

This work examines the effect of heat treatment on tensile strength and ductile responses of rolled and forged AA6063 aluminum alloy. Some cast samples were rolled while some were forged at ambient temperature (32C). The deformed samples were subjected to heat treatment processes. The tensile strengths of rolled (212 MPa) and forged (127 MPa) samples are enhanced at ambient temperature but with...

به منظور تولید رادیوایزوتوپ تکنسیم-۹۹ حاصل از واپاشی رادیواکتیو مولیبدن-۹۹ و خالص‌­سازی محصول فرایند انحلال اسیدی هدف مینیاتوری، لازم است آلودگی ید گازی در حد قابل قبولی کاهش یابد. این جاذب‌های جامد استفاده می‌شود. یکی بهترین مورد موردنیت حاوی نقره تشکیل شده است. پژوهش روش سنتز مشخصات جاذب بررسی قرار گرفته برای تهیه بلورهای حفره‌دار با اندازه حدود ۱۰ میکرومتر نسبت آلومینیم سیلیکون برابر 2/5 شد ...

The effect of speed and time stirring for AA6063 matrix manufactured by Electric Induction Furnace reinforced 0.75wt.% 1.5wt.% Al2O3 nanoparticles is studied. Specimens produced were subjected to tensile, microhardness, tribology tests. It observed that an increase in the agitation samples with 0.75%, favors grain size, while opposite pieces 1.5%, where a refining favored, affecting mechanical ...
