The Investigation of Aluminum Crystallization Process Using Acoustic Emission Method

The article discusses the method of acoustic emission, allowing to predict the structure of the metal during casting. The experimental data were analyzed during crystallization of aluminum of grade A99 in an unmodified state and aluminum of grade A99, with the addition of AlTi5B1 modifier in an amount of 0.02% Ti. Dependence of main parameters of acoustic emission signal on dependence of aluminum macrostructure is established.
