High-Temperature Cyclic Fatigue-Crack Growth in Monolithic Ti3SiC2 Ceramics

identical slip planes) and walls or kink boundaries. Thus, in addition to regular slip, mechanisms for ambient temperature The cyclic fatigue behavior of reactive hot-pressed Ti3SiCz plastic deformation in Ti3SiCz are thought to involve the ceramics are examined at temperatures from ambient to 1200°C readjustment of local stress and strain fields from kink band with the objective of characteriz...

Strength of Polycrystalline Ceramics under Shock Compression

Processing and Characterization of Nanocrystalline Mica Glass-Ceramics

In order to fabrication of transparent glass-ceramics with Li-mica nano crystals, the glasses with chemical composition of 94.9 mass% Li(1+x)Mg3AlSi3(1+x)F2 (x=0.5) with 5.1 mass% MgF2 were crystallized. The glasses were fabricated via the conventional melt-quenching technique. Mica crystals were precipitated in the glass phase by later heat treatment. Glass samples had glass transition tempera...

Colloidal Processing of Ceramics

Colloidal processing of ceramics is reviewed with an emphasis on interparticle forces, suspension rheology, consolidation techniques, and drying behavior. Particular attention is given to the scientific concepts that underpin the fabrication of particulate-derived ceramic components. The complex interplay between suspension stability and its structural evolution during colloidal processing is h...

Visualizations of molecular dynamics simulations of high-performance polycrystalline structural ceramics

The Data Analysis and Assessment Center (DAAC) serves the needs of the Department of Defense (DOD) High Performance Computing Modernization Program (HPCMP) scientists by facilitating the analysis of an ever increasing volume and complexity of data [1]. Dr. Charles Cornwell is a research scientist and HPCMP user who ran nanoscale molecular dynamics simulations using Large-scale Atomic/Molecular ...
