|On-Site Speaker (Planned)
The aim of the present study is to evaluate the Spark Plasma Sintering (SPS) as a possible route to produce TiAl blades for aircraft engines. The first part of this talk will be devoted to the development of a performing alloy, called IRIS, offering a good compromise between creep resistance at high temperature and significant plastic elongation at room temperature. We’ll start describing the optimization of its chemical composition and processing conditions. Then, microstructures and the mechanical properties will be successively presented. In the second part, we’ll depict the method used to sinter near-net shape blades by SPS, using modified graphite die and punches, which compress the powder, to obtain the final shape of the engine component.
