Casting and solidification research at TATA Steel Europe

Dr Begoña Santillana, Principal Scientist at TATA Steel Europe, presents an overview of the methods used in assessing whether new alloys will be susceptible to solidification cracking when cast. A combination of equilibrium thermodynamics and non-equilibrium solidification methods such as those embedded in the Scheil technique can be used to define parameters such as the expected solidification range. With this knowledge, and when temperature-depended mechanical properties are available, they can be used to either modify the solidification process or to change the steel composition in order to avoid difficulties as the material solidifies. The seminar is organised and chaired by Associate Professor Prakash Srirangam Venkata, as a part of a series of seminars at the Warwick University Manufacturing Group.
