The influence of the laser scan strategy on grain structure and cracking behaviour in SLM powder-bed fabricated nickel superalloy
TL;DR: In this paper, the authors used optical and SEM micrographs to show the observed grain structure in the SLM fabricated and Hot Isostatically Pressed (HIPped) material and found that the repeating pattern shown in the grain structure has been linked to the overlapping of the "island" pattern used as standard in the Concept Laser M2 powder-bed facility.

Fatigue of materials
TL;DR: In this article, the cyclic deformation and fatigue crack initiation in polycrystalline ductile solids was studied and a total-life approach was proposed to deal with the problem.
Journal ArticleDOI
SGTE data for pure elements
TL;DR: In this article, the authors present the data for the condensed phases of 78 elements as currently used by SGTE (Scientific Group Thermodata Europe) as a sound basis for the critical assessment of thermodynamic data, thereby, perhaps, limiting unnecessary duplication of effort.
Journal ArticleDOI
Thermo-Calc & DICTRA, computational tools for materials science
TL;DR: It is shown how advanced thermodynamic calculations have become more accessible since: - A more user-friendly windows version of Thermo-Calc, TCW, has been developed, and there is an increasing amount of thermodynamic databases for different materials available.
Journal ArticleDOI
Mechanisms controlling the durability of thermal barrier coatings
TL;DR: In this paper, the authors present relationships between the durability, the governing material properties and salient morphological features of thermal barrier coatings and show that the failure is ultimately connected to the large residual compression in the thermally grown oxide through its roles in amplifying imperfections near the interface.
Journal ArticleDOI
Progress in structural materials for aerospace systems
TL;DR: The focus of this paper is aircraft and aircraft engines but the broader focus is on the role of materials in creating lightweight structures, and there are examples used that are relevant to automotive applications once they are adjusted for cost.
