INFLUENCE OF SI PHASE ON FATIGUE PROPERTIES OF ALUMINIUM ALLOYS

1. Introduction
Aluminium alloys are currently being used as major structure components in automobiles, high-speed railway vehicles and aircrafts, which are often subjected to a cyclic loading. It is necessary to predict their cyclic responses as accurately as possible by construc[r]

When perfectly clean, flat metal surfaces are brought into close proximity (less than 1/5 nm) they unite chemically. When separation is wider, they are attracted to each other by van der Waals’ forces. At small separations (less than 10 –8 m) these are governed by a square law and at grea[r]

The research in the field of cementitious materials has brought towards many non-traditional binder systems. One of these systems, a ternary binder composed of calcium aluminate cement (CAC), ordinary Portland cement (OPC), and calcium sulfate (C$Hx), called ettringite binder, offers a possibility o[r]
