This study used scanning electron microscopy with an backscatter diffraction system to the refinement mechanism of proeutectoid ferrite (Pro-F) and eutectoid (Eut-F) in a D2 wheel steel under rolling contact conditions. The results indicate that as shear strain increased (γ < 0.21), dislocation density continuously, formed cells were distributed uniformly grains. Subsequently, cell boundaries c...
ABSTRACT The binary system Cu-Sb is a constituent system that is studied in investigations of technically important ternary and quaternary alloy systems (e.g., casting alloys and lead-free solders). Although this binary system has been thoroughly investigated over the last century, there are still some uncertainties regarding its high-temperature phases. Thus, parts of its phase diagram have be...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
فرآیند نورد تجمعی (accumulative roll bonding (arb)) یکی از رایج ترین روش ها برای تولید مواد ورقه ای فوق ریزدانه شده می باشد. این روش شامل چرخه های مختلفی از نورد، برش و پشته سازی است و تا مرز امکان می تواند تکرار شود. در این تحقیق، کامپوزیت چندلایه al/steel با استفاده از ورق های 1100al- و 12st- به روش arb و تا سه چرخه تولید شد. میکروساختار و خواص مکانیکی کامپوزیت چندلایه al/steel در چرخه های مخ...
