Lecture summary

Processing of metals is a science, art and hobby and its history can be dated back to 5000BC when small pieces of copper were hammered and ground to make the first tools and weapons. Nowadays, metal processing, through innovation, has been industrialised and is the most economic and effective way to make individual parts, assemblies or large scale structures. Most important innovations in metal processing throughout history were made through trial and error experiments. However this has changed dramatically over the last 20 years as computational modelling becomes a more and more powerful tool in metal processing research.  
In this lecture I will explain, through case studies, how to develop models for metal processing and how the models can be used to simulate metal processing. Simulations of the movement of iron atoms during steel solidification can reveal information that would not be available otherwise. Modelling how to grow a single crystal turbine blade that can operate at 1500C next to the combustion chamber of a modern jet engine is another example. These case studies demonstrate that predictions based on modelling can provide an innovative and more rapid way to design and optimise new processes than by the trial and error methods.
 
With the advances in computer modelling, metal processing is moving away from empirical choices of process variables to optimised processes producing designed components and structures. An integrated approach of materials, processing and modelling is emerging in manufacturing industry that has transformed the engineering process and unified design and manufacturing.
