Waste polymers are widely used in asphalt modification, especially, order to reduce their detrimental effect on the environment. This study discusses usability of waste expanded polystyrene (EPS) foam modification. In this respect, EPS foam, which produces both production and use stages, was mixed with bitumen by weight at ratios 2%, 4%, 6%, 8%, dry modification method employed. The penetration...

Herein, the bending behavior of a hot-rolled hyper-sandelin steel subjected to hot-dip galvanizing (HDG) is numerically simulated. Two coating types are analyzed, that is, pure zinc and zinc-based with 3% Sn addition by weight. It experimentally observed tin influences thickness each intermetallic phase increases ductility phases. Therefore, key numerical simulation assume suitable constitutive...

The high strength Al-Zn-Mg alloy is widely used for structure components in critical aerospace applications. Small additions of scandium (Sc) often refine cast microstructure and mechanical properties by forming metastable Al3Sc dispersoids. The main role of the Al3Sc dispersoid is to prevent recrystallization during hot deformation and solution treatment. A new technique to apply for surface m...

Weight reduction is often considered the primary goal in development of structure materials. A new Ti-8Al-1Cr-1V-0.5Fe-0.1Si (wt.%) alloy with a low-density and high-strength was developed this work. The microstructures mechanical properties were investigated hot-rolled solution-aging (STA) treatment conditions. both states consist spherical αp phase, acicular αs small amount β phase. Attribute...
