1. High strain rate deformation of Alloy 718, Influence of Microstructure on Mechanical Properties
Abstract : Alloy 718 is a high temperature alloy, used where high temperature strength or oxidation resistance is required. As the alloy is precipitate heat treatable, it is possible to have a large variety of deformation and mechanical properties depending on microstructure. READ MORE

2. Modeling and Simulation of CGI Machining on Microstructure Level
Abstract : incorporation of new design materials – e.g. in order to promote lightweight design – oftenleading to significant changes in manufacturing conditions, which can be assessed in anefficient way by simulation rather than more expensive testing. READ MORE

3. Modeling of cast iron materials related to machining
Abstract : A microstructure level simulation model of cast iron machining based on micrograph image analysis has been developed. The simulation tool has been developed for theorthogonal machining process involving 2D representations of a range of cast iron microstructures. READ MORE

5. Plasticity modelling of nickel based super alloy Alloy 718
Abstract : The ever growing demand on reduced fuel consumption in modern aircrafts puts high requirements on manufacturers to reduce weight in all parts of the aircraft. With a total weight of up to one fifth of an aircraft’s total operating weight, ways to decrease the weight of the engine systems are continuously sought. READ MORE
