Electron microscope study of microtexture and grain surfaces in limestones

Electron micrographs of directcarbon replicas having magnifications of 5400 to 23, 500 times reveal in detail the grain size, shape, and packing of the particles comprising very fine-grained limestones. At these magnifications, however, only portions of a few grains in mediumor coarsegrained limestones can be observed. Grain contacts are mostly curvilinear in very fine-grained limestones but ar...

From Simple Shapes to Microstructural Grain Structure: An Inquiry

Based on serial sectioning data, materials microstructure can be reconstructed to digitally represent each grain in three dimensions. This paper attempts to calculate the average shape of the grains through Principal Component Analysis(PCA) , with a theoretical introduction to how this method can be generalized into calculating an average shape of the microstructure. Also investigated is the re...

Microstructural investigations of EBPVD thermal barrier coatings

This paper deals with the morphology, constitutive phases and fine microstructures of some EBPVD processed yttria partially stabilized zirconia thermal barrier coatings. This study has been performed by X-ray diffraction and scanning and transmission electron microscopy. It was shown that the coatings studied were constituted of a single metastable tetragonal t' phase, as expected if one refers...

Effect of Thermal History on Microstructural Changes in Aluminized Nickel-Based Single-Crystal Superalloy

The effect of the thermal history on microstructural changes in aluminized and Pt-aluminized Ni-based single-crystal superalloys was investigated. The superalloy substrates were first electropolished to get rid of the residual surface strain. Then, Pt was electrodeposited and vacuum annealing was conducted for some of the substrates, and aluminized and Pt-aluminized specimens were prepared usin...
