Abstract:
Part I of this report, dated September 1965, deals mainly with
the design and construction of the special apparatus to simulate the
stress redistribution occurring during the creep of a cooled turbine
blade. It reported some preliminary experiments using aluminium alloy
test specimens.
During the past year, the period covered by this report, a series
of experiments have been completed using specimens machined from nimonic
90 alloy.
Experience gained in operating the apparatus, have resulted in
several modifications both to the apparatus and the associated instrumentation.
These are detailed within this report.
