Growth of a single crystal and characterisation towards optimising ultrasonic inspection of austenitic welds
Inspection of austenitic welds in stainless steels and nickel alloys is a critical area of activity for both the nuclear and oil & gas industries, and also the aerospace industry in niche areas.
The solidification of the weld leaves an inhomogeneous anisotropic weld which adversely affects inspection performance – primarily in characterisation of the flaw type, its positioning within the weld and sizing. Work done to date has made significant advances in detection performance through the use of twin-crystal phased array probes in transmit-receive longitudinal (TRL) configuration. However, sizing and characterisation of the detected flaws is key to decision making in nuclear power plants and oil & gas components.
TWI has made advances in addressing this issue and this PhD will take forward those concepts to aid in developing a viable inspection system for austenitic welds.
A number of fully-funded PhD scholarships are available for suitable candidates with a strong interest in fundamental and applied research in the area of structural integrity. Scholarships cover an amount to £16,000 per annum for 3 years, Home/EU tuition fees and support for research. Overseas applicants are welcomed, with total funding capped at £20k/year.
Candidates should have a relevant degree at 2.1 minimum, or an equivalent overseas degree in mechanical, Electrical/Electronics or Civil/Structural Engineering, Material Science, Metallurgy or Physics. Candidates with suitable work experience and strong capacity in numerical modelling and experimental skills are particularly welcome to apply. Overseas applicants should also submit IELTS results (minimum 6.5) if applicable.
