چکیده
The oxidation behavior of the Ni-base single-crystal superalloy AM1 was investigated over temperature range 750–1300 °C. use stepwise multi-temperature thermogravimetric analysis (SMT-TGA) showed presence a transient regime. This regime can be modeled by initial formation fast-growing mixed oxide and then ?-alumina gradually covering metal/oxide interface. model helps to determine time required for alloy out Then, makes it possible predict any kinetics entire studied.

15 صفحه اولModelling plastic deformation in a single-crystal nickel-based superalloy using discrete dislocation dynamics
Background: Nickel-based superalloys are usually exposed to high static or cyclic loads in non-ambient environment, so a reliable prediction of their mechanical properties, especially plastic deformation, at elevated temperature is essential for improved damage-tolerance assessment of components. Methods: In this paper, plastic deformation in a single-crystal nickel-based superalloy CMSX4 at el...
متن کاملPreferred growth orientation and microsegregation behaviors of eutectic in a nickel-based single-crystal superalloy
A nickel-based single-crystal superalloy was employed to investigate the preferred growth orientation behavior of the (γ + γ') eutectic and the effect of these orientations on the segregation behavior. A novel solidification model for the eutectic island was proposed. At the beginning of the eutectic island's crystallization, the core directly formed from the liquid by the eutectic reaction, an...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Crystal plasticity and crack initiation in a single-crystal nickel-base superalloy Modelling, evaluation and applications
In this dissertation the work done in the projects KME-410/502 will be presented. The overall objective in these projects is to evaluate and develop tools for designing against fatigue in single-crystal nickel-base superalloys in gas turbines. Experiments have been done on single-crystal nickel-base superalloy specimens in order to investigate the mechanical and fatigue behaviour of the materia...
