Stress Relaxation Behavior of Molten Slags

Comparison of Compressive Stress-Relaxation Behavior

Osteoarthritis (OA) is a common joint disorder found mostly in elderly people. The role 21 of mechanical behavior in the progression of OA is complex and remains unclear. The 22 stress-relaxation behavior of human articular cartilage in clinically defined osteoarthritic stages 23 may have importance in diagnosis and prognosis of OA. In this study we investigated differences 24 in the biomechani...

The structural relaxation of molten sodium disilicate

We use molecular dynamics computer simulations to study the relaxation dynamics of Na2O–2(SiO2) in its molten, highly viscous state. We find that at low temperatures the incoherent intermediate scattering function for Na relaxes about 100 times faster than the one of the Si and O atoms. In contrast to this all coherent functions relax on the same time scale if the wave–vector is around 1Å. This...

[Physical properties and metal elutions of the thirteen molten slags produced from incinerated ash].

In recent years, there have been many attempts to reuse molten slag. Molten slag is obtained through further treatment of incinerated ash produced in the disposal process of garbage or sewage sludge and is used in building materials, such as brick. To establish the safety of such slag, its physical properties and metal contents were investigated in this study. After examining the physical and c...

Creep and Stress Relaxation Behavior of Polypropylene, Metallocene-Prepared Polyethylene and their Blends

FLOW BEHAVIOR OF MOLTEN METAL IN ALUMINUM LFC PROCESS

The effects of gating system and pattern geometry on the metal flow in the lost foam casting (LFC) process have been investigated using glass covered mold and video recording system. Unlike convectional casting process, the type of the gating system showed little effect on fillability in lost foam, but pattern thickness had large effect on mold filling. The mold filling behavior seems to be con...
