Martin Miller

Topics - Mechanical testing (creep, stress rupture, fatigue (HCF and LCF), hardness and tensile). - Microscopy; optical, EBSD, SEM and TEM. - Forging processes and their associated NDT techniques (Ultrasonic, Etching, FPI and MPI). - Contribution from a materials engineering perspective to the stress and lifing activities (ex. relationships between the metallurgical surface condition produced by the machining processes and the fatigue behaviour of the materials). - Materials data processing. - Cold and hot corrosion mechanisms. - Materials capability acquisition. - Implementation of new special processes in order to improve the life of components. - Problems solving. - Technical audits. Metallurgy - Titanium materials used for compressor blades and discs applications. - Nickel based superalloys used for turbine blades and discs applications. - Steels (martensitic stainless steels and HSLA) used for turbine discs, compressor vanes and shaft applications. Special processes Shot peening, laser shock peening, carburizing, nitriding, plasma spraying, welding (EBW, microplama welding and TIG). Coatings Plating (Cr and Ni), sacrificial corrosion protection coatings, hot corrosion protection coatings and abradable coatings. Machining processes Broaching (turbine discs), grinding, milling and turning. Technical support to the Materials engineering group and to the other engineering departments, i.e. Design, Fleet, Manufacturing, Repair and Stress & Lifing. Technical support to cost reduction activities.
