Microstructural evolution during ageing of Al–Cu–Li–x alloys

Microstructural Evolution of X45CrNiW189 Valve Steel During Hot Deformation

The hot compression tests were carried on X45CrNiW189 valve steel (X45) in the temperature range of 1000– 1200 °C and the strain rate range of 0.004 – 0.5 s-1 in order to study the high temperature softening behavior of this steel. For the exact prediction of flow stress, the effective stress-effective strain curves were obtained from experiments under various conditions. On the basis of experi...

Microstructural evolution during film growth

Atomic-scale control and manipulation of the microstructure of polycrystalline thin films during kinetically limited low-temperature deposition, crucial for a broad range of industrial applications, has been a leading goal of materials science during the past decades. Here, we review the present understanding of film growth processes—nucleation, coalescence, competitive grain growth, and recrys...

Simulation of Microstructural Evolution during Tmc Monotape Consolidation Processing

The consolidation of fiber-reinforced titanium matrix composite (TMC) monotapes produced by spray deposition is an important step in the manufacture of TMC components. The performance of this class of composites is controlled by fiber-matrix properties and by the composite’s relative density, fiber microbending stress/fracture and by the interfacial reaction layer thickness at the fiber-matrix ...
