Phase-field simulations of cemented carbide inserts Introduction

Microstructure

FlexPDE

Researcher: Kristina Wessén

This project is done in cooperation with Sandvik Tooling's research and development department.

After investigation of different software products was flexPDE further studied.

Supervisors: Henrik Strandlund Sandvik AB Maya Neytcheva

The work consider a simple model problem where one grain, due to a chemical driving force, is growing at the expense of another grain.

Since the microstructure to a large extent determines the properties of a material it is of importance to be able to predict the temporal evolution of the microstructure during processing of the material.

By first solving this problem in MATLAB it's possible to evaluate different software and tools, ranging from user-friendly commercial software to numerical FORTRAN libraries.

FlexPDE is a software for obtaining numerical solutions to PDE in one, two or three dimensions. The program is based on the finit element method and can solve both steady-state or timedependent problems.

The results are presented below.

Phase-field equation depending on the state in space z.

Diffusion equation depending on the state in space z.

The software program's disadvantage is that it is not possible to change the algorithms that perform calculations which reduces flexibility and is not optimal for many problems.
