Nucleation and structuring in aluminum and in AlSi12Cu2NiMg alloy with nanopaticle modifier under impact of electron-beam treatment

The paper presents experimental and theoretical study of crystal nucleation and growth in aluminum and structure development in the aluminum melt after the introduction of a cubic-shaped nanoparticle modifier and using the electron-beam surface treatment method. The output of this study is the rate of solid phase nucleation as a function of TiCN nanoparticle size dispersed in molten aluminum. The numerical simulation of crystal structure growth for a sample of AlSi12Cu2NiMg alloy treated by electron beam was performed using the MAGMASOFT computer code.
