Characterisation of the gamma prime precipitate distribution in an advanced N...
The excellent high temperature properties of Ni-base superalloys are derived from the presence of fine precipitates of the intermetallic Ni3Al phase, termed gamma prime. The... -
The effect of γ′ particle size on the γ/γ′ load tr...
The aim of this experiment is to measure the load transfer between the matrix and the precipitates in an advanced nickel¿base superalloy as a function of particle size... -
Quantifying the role of stresses in the cracking of repair welds in nickel su...
Repair welding of nickel superalloys is being investigated at Cranfield University to determine repair techniques which minimise liquation and post-weld heat treatment cracking... -
In-situ stress relaxation during heat treatment in sub-scale forgings of Nick...
Advanced materials such as polycrystalline Ni superalloys put increased pressure on developing appropriate thermomechanical procedures, which avoid the generation of large... -
Influence of rafted microstructures on the in-situ strain response of single ...
The proposed experiment concerns the role of microstructure on the high temperature deformation behaviour of single crystal Ni-base superalloys. This class of material is of... -
Continuation: In situ neutron diffractometry of single crystal superalloys
We propose to carry out in-situ neutron diffractometry on testpieces of a latest-generation single crystal superalloy. This work is in support of current EPSRC projects... -
Characterisation of superalloys strengthened by Co3Ti
One method by which the efficiency of gas turbine engines may be improved is by increasing the gas stream temperature on entry to the turbine. Currently this temperature is...
