A new technique for the preparation of site specific plan-view specimens using a focused ion beam system is presented. The technique consists of milling a wedge shaped piece of material which is free from the substrate, lifting this out using a micro

Next generation aberration correctors will not only eliminate the third-order spherical aberration, but also improve the information limit by correction of chromatic aberration. As a result of these improvements, higher order aberrations, which have

We present experimental evidence that deformation can induce the transformation of small Cu-rich precipitates from the coherent bcc phase to the 9R phase in aged binary FeCu alloys. This is in broad agreement with molecular dynamics simulations of th

Sub-micron sized SiC additions can be used to increase the wear resistance and change the fracture mode of Al2O3. However, these additions also restrict sintering. Al2O3 and Al2O3-5%SiC 'nanocomposites' were prepared from alumina powders of high puri

It is important to know the degree of plastic strain in order to evaluate the susceptibility and crack growth rate of stress corrosion cracking (SCC) in stainless steel and nickel based alloy, because SCC is enhanced by the cold work and causes many

Electron backscatter diffraction (EBSD) in conjunction with scanning electron microscopy is applied to assess the plastic strain present in stainless steel and nickel alloys following tensile loading. A parameter, which quantifies the spread of the c

The optimisation of parameters is investigated for the compositional analysis of nanometre-sized particles embedded in a matrix by energy-filtered transmission electron microscopy. The specific example of Cu-rich particles in a Fe matrix is used both

Type 316 stainless steel foils containing stress corrosion cracks grown in high temperature aqueous environments have been examined by transmission electron microscopy. It was found that the crack tips are oxidized and have a three-layered morphology

A novel technique for the quantification of the iron content of copper precipitates in ferritic steels is presented. Energy-filtered (EF) imaging has been used to extract elemental maps with high spatial resolution. These maps contain enough informat
