A physical metallurgy laboratory manual
… the graduate who intends to continue his work in metallurgy, a series of experiments has been carefully planned, performed, and thoroughly studied to determine their value to the student. This work was done under the direction and direct supervision of Professor H. V. White, Head of the Department …

Nanocrystalline copper-tantalum composites
This research investigated the physical metallurgy, high temperatures coarsening, and processing/structure relationships for Cu$\sb{\rm 1-x}$Ta$\sb{\rm x}$ (x = $\sim$5 to 20 atomic percent) alloys. These metastable alloys were produced using a plasma assisted physical vapor deposition (PAPVD) …

Integrated environmental degradation model for Fe-Ni-Cr alloys in irradiated aqueous solutions
… based on first principles electrochemistry and physical metallurgy. The effect of neutron and gamma radiation dose is included so that irradiation assisted stress corrosion cracking can be studied. By integrating the bulk chemistry with crack tip processes, the crack growth behavior of an …

Modelling Precipitation of Carbides in Martensitic Steels
… The thesis begins with a review of the physical metallurgy of secondary hardening steels and the phenomena of hydrogen embrittlement and hydrogen trapping. The basic theory for the precipitation processes, including the nucleation and diffusion-controlled growth of particles, is reviewed …

Modelling of Simultaneous Transformations in Steels
The microstructure of a steel is often developed by solid-state transformation from austenite. The major transformation products are allotriomorphic ferrite, pearlite, Widmanstatten ferrite, bainite and martensite, differentiated by morphological features, and their nucleation and growth …

Deformation Behaviour of NiCo Multilayers with Modulated Microstructures
Metallic multilayers, which possess a material architecture of modulated coarse-grained and nanocrystalline features stacked in a laminate configuration, represent an ideal structure to study the influence of abrupt heterogeneities on deformation behaviour. While the deformation mechanisms of …

Deformation mechanisms in a polycrystalline Ni-based superalloy
In order to reduce emissions from aviation, the most straightforward approach is to increase jet engine service temperatures. However, this raised temperature window extends into a new deformation mechanism regime that needs to be explored and understood to be able to design and optimise new and …

Theory and significance of retained austenite in steels
The processes leading to the retention of small quantities of austenite following the bainite and martensite phase transformations have been examined, together with the influence of retained austenite on the properties of low alloy steels. It was found that the upper and lower bainite …
