MAGMAacademy News 1/2023

Dear Sir or Madam,

The New Year has started rapidly and we welcome you to your MAGMAacademy newsletter in February 2023!

Today's technical article is about an exclusive event offer of the MAGMAacademy, which takes place once a quarter every year and which addresses all potential users of casting process simulation: Together with a MAGMA expert, you reproduce your situation from production realistically in the simulation and thus jointly develop robust and targeted simulation results. You have the opportunity to get to know MAGMA as a strong partner at your side.

Moreover as a MAGMASOFT^® user you will find news from the LEARNING WORLD at the end of this technical article.

We send you our best greetings from Aachen!

Your MAGMAacademy team

Influence of Local Cooling Rates on Microstructure and Properties of Cast Iron Alloys

The microstructure and, thus, the mechanical properties of cast iron alloys are essentially dependent on

• the chemical composition
• the number of nuclei
• the local cooling rates.

To make reliable predictions, simulation models need to take these three influencing parameters into account.

The fraction of eutectic phase that occurs in equilibrium for a composition during solidification can be described via the corrected degree of saturation S_R according to E. Piwowarsky (fraction of eutectic solidification/total solidification)  →  (C-C_E)/(C_C-C_E).

In the following example of an alloy with a carbon equivalent (CE) of 3.9 %, the eutectic fraction is 83 %, see Figure 1.
