با توجه به اینکه آلومینیوم 5083 یکی از پرکاربردترین مواد در سازه موشک، حامل و کاوشگر­های فضایی است. در این مقاله، فرآیند آسیب پیوسته در آلومینیوم 5083 بر اساس مدل‏های غیر خطی بنورا و لیمیتر بررسی شده است. آزمون عملی بر روی چهار مدل قطعه با شرایط بارگذاری مختلف انجام شده و اثر بارگذاری سیکلی، تنش سه بعدی و دما بر روی گسترش آسیب مورد بررسی قرار گرفته است. برای پیش بینی رفتار ماده در مدل­سازی عددی...

Epoxy coatings incorporating different content of sulfosalicylic acid doped polyaniline (PANI-SSA) have been investigated for corrosion protection of 5083 aluminum alloy in 3.5% NaCl solution. The performance of the coatings is studied using a combination of electrochemical impedance spectroscopy (EIS), open circuit potential (OCP), gravimetric tests, adhesion tests, scanning electron microscop...

The 5000 series non-heat-treatable Al–Mg alloys are widely used as structural members, because of excellent combination weldability, corrosion resistance and mechanical properties. It is well known that these can become susceptible to inter-granular stress cracking. In the previous paper, authors revealed hydrogen embrittlement (HE) takes place in weld corner (fusion zone adjacent HAZ) an MIG-w...
