Micro alloyed high strength net shape components

Project Details


The need to reduce costs and save resources creates a natural drive towards the development of new stronger and/or lighter materials. The project aims at developing new low cost materials with increased strength so that wind turbines and other heavily loaded constructions can be made with reduced weight at no significant increase in production costs.
The main scientific objective of the project is to investigate formation of microstructures in a new family of ductile cast irons experimentally and to develop models for formation of microstructures that can be implemented in numerical codes for process modelling.
The first part of the project is directed towards analysis of how microstructures in the materials develop during solidification and subsequent cooling to room temperature. Highly advanced 3D analysis of microstructures using a range of new techniques provided by the new microscopes at CEN●DTU that allows us to characterise the materials from nano-scale to mm-scale will be used to describe the true 3D microstructure of highly complex high strength materials.
The microstructure analysis will be used to develop models that describe the chemical and thermodynamic processes that lead to the formation of phases as a result of processing conditions.
A valuable output of the project will be a better understanding of the evolution of the metallic structure during solidification and subsequent cooling to room temperature. The technological objectives are aimed at a more efficient exploitation of the material by supplying realistic mechanical characteristics in the design phase. Efficiency of design, achieved by means of the use of optimisation techniques, will in turn supply strong reductions on testing time, lead-time to market and costs for the industries and end users.
