Résumé : 

In the present work the finite element method is used to analyze the distribution and the level of residual stress induced in a matrix by the phenomena of precipitation Fe2C compounds resulting from the process of welding. The effect of temperature and the interaction between precipitates on the residual stress level were highlighted
