    Investigation into the Effects of Salt Chemistry and SO2 on the Crack Initiation of CMSX-4 in Static Loading Conditions

    Although evidence exists of the potential impact of stress, co-incident with corrosive environments at high temperature, for single-crystal turbine blades, the mechanism responsible is not fully understood. Th...

    New Technique to Map Hot Corrosion Damage: CMSX-4 Example

    Despite their extraordinary properties, superalloys are subject to hot corrosion; a phenomenon potentially leading to catastrophic failure of turbine blades. However hot corrosion is understood to be highly te...

    The Effect of Volatilisation of Refractory Metal Oxides on the Cyclic Oxidation of Ni-base Superalloys

    The role of refractory metals on the bare oxidation behaviour of a range of compositionally complex single crystal Ni-base superalloys has been investigated using a range of techniques. It has been shown that ...

    Characterization of InP/GaInAs Nanometer Sized Columns Produced by Aerosol Deposition and Plasma Etching

    We present a technique for the fabrication of InP nano-columns and GaInAs/InP quantum-dots based on the use of sintered aerosol Ag particles as a mask in an electron cyclotron resonance etching process. The si...
