Dislocations and twinning in graphite

Kennedy, A. J. (College of Aeronautics, 1960-04)

The twin composition plane in graphite is a 20o tilt boundary between lattices which are rotated, relatively, about an axis In the basal plane. Previous work has led to the proposition that some special type of structure ...
Graphite as a structural material in conditions of high thermal flux: a survey of existing knowledge and an assessment of current research and development

Kennedy, A. J. (College of Aeronautics, 1959-11)

The state of fundamental knowledge on the subject of graphite and the graphitisation process is reviewed. The principle methods of manufacture may be considered to include (1) conventional graphitisation of a coke ...
Temperature effects on material characteristics

Murphy, A. J.; Kennedy, A. J. (College of Aeronautics, 1960-08)

Some of the physical properties of the main elements of interest in high temperature technology are reviewed. Some general trends emerge when these properties are viewed as a function of melting point, but there are a ...
