Microstructural evolution in service exposed low alloy power plant steels
thesis
posted on 2015-02-20, 15:14 authored by Kate BurkeThis work forms part of the EPSRC Supergen 2 Lifetime Extension of Conventional
Power Plant project. In particular this research investigates the remaining life of a
number of ditferent YzCr YzMo 'i4 V power plant steels which have been in service for
considerable lengths of time and which have subtle differences in chemical
composition, microstructure and mechanical properties. The low alloy ferritic steels
all operate in the creep regime and therefore resistance to creep is an important
microstructural characteristic. There are a number of key questions which this
research aims to address: Having endured this extensive time in service how do
engineers within the power industry know that the component is still safe to run?
Even as the components reach and often exceed their original design life, it is
important to safely extend the lives of existing conventional plant in a bid to ensure
that the country's electricity supply remains intact... cont'd.
