RESUMO
The present paper describes an experimental testing method connected with use of the thermal-voltage-derivative analysis (the ATND method in short) to crystallization recording of the AlSi13Cu2Fe eutectic alloy in aspects of possible prediction of its mechanical properties, basing on dependencies obtained from regression analysis, performed on the basis of temperature and voltage values of characteristic points seen on curves from the ATND method. Results of the experiment have demonstrated a significant relation between values of the characteristic points from the ATND method and the mechanical properties (yield strength R0,2 and hardness HB 10/1000/30). Moreover, obtained dependencies have enabled prediction of the yield strength R0,2 and the hardness HB 10/1000/30 as early as at preparation stage (melting) of the investigated alloy, what allows quick correction of performed modification process.
