Electron Microscopy Studies of Bonding Interface in Explosively Welded Ti/Steel Clads.

Transmission Electron Microscopy Studies of Electrical Active GaAs/GaN Interface Obtained by Wafer Bonding

Transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX) studies of GaAs/GaN interfaces, obtained by direct wafer bonding, are presented. TEM observations show that most of the interface area was well bonded. A thin oxide layer, confirmed by EDX, was present at the interface in the well-bonded regions. Plan-view TEM studies showed the presence of two dislocation net...

Defects characterization of welded specimens by transmission electron microscopy

Austenitic Type 304L stainless steel (SS) and martensitic Alloy EP-823 have been identified as candidate structural materials to contain spallation arget for transmutation of nuclear waste. Welded specimens consisting of either or both materials have been evaluated by transmission electron icroscopy (TEM) to determine the dislocation density near the heat-affected-zone (HAZ) and the base materi...

EFFECT OF DIFFUSION ANNEALING ON PROPERTIES OF TI/304L STAINLESS STEEL EXPLOSION CLAD

In this study, commercially pure titanium/304L stainless steel explosion bonded clads have been annealed under argon atmosphere over the temperature range of 700-900°C for 1h.Microstructure of the clads have been investigated before and after anealing. X-ray diffraction studies revealed that the annealing products in the form of intermetallic phases were gradually formed at the interface of the...

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...
