Fracture Behavior and Delamination Toughening of Molybdenum in Charpy Impact Tests

This study combines advanced characterization techniques with conventional Charpy impact tests to relate the mechanical properties to the microstructure of technically pure molybdenum, especially regarding its toughness. V-notched samples with different orientations were prepared from a rolled molybdenum plate in stress-relieved and recrystallized condition. The ductile-to-brittle ...

Materials Selection in Gas Turbine Engine Design and the Role of Low Thermal Expansion Materials

Materials selection criteria in gas turbine engine design are reviewed, and several design challenges are introduced where selection of low coefficient of thermal expansion (CTE) materials can help improve engine performance and operability. This is followed by a review of the types of low CTE materials that are suitable for gas turbine engine applications, and discussion of their ...

Thermo-Mechanical Behavior of the Continuous Casting Bloom in the Heavy Reduction Process

A two-stage sequential heavy reduction (HR) method, in which the reduction amount was increased both before and after the solidification end, is presented to simultaneously improve the homogeneity and compactness of the continuous casting bloom. With bearing steel GCr15 chosen as the specific research steel, a three-dimensional thermal–mechanical finite element model was developed ...

Simulation in Metallurgical Processing: Recent Developments and Future Perspectives

This article briefly addresses the most important topics concerning numerical simulation of metallurgical processes, namely, multiphase issues (particle and bubble motion and flotation/sedimentation of equiaxed crystals during solidification), multiphysics issues (electromagnetic stirring, electro-slag remelting, Cu-electro-refining, fluid–structure interaction, and mushy zone ...

Development of Semantic Description for Multiscale Models of Thermo-Mechanical Treatment of Metal Alloys

We present a process of semantic meta-model development for data management in an adaptable multiscale modeling framework. The main problems in ontology design are discussed, and a solution achieved as a result of the research is presented. The main concepts concerning the application and data management background for multiscale modeling were derived from the AM3 ...
