The work is a continuation of research on the use water mist cooling in order to increase efficiency of die-casting aluminum alloys using

multipoint water mist cooling system. The paper presents results of investigation of crystallization process and microstructure of synthetic

hypereutectic AlSi20 alloy. Casts were made in permanent mold cooled with water mist stream. The study was conducted for unmodified

AlSi20 alloy and modified with phosphorus, titanium and boron on the research station allowing sequential multipoint cooling using a

dedicated program of computer control. The study demonstrated that the use of mold cooled with water mist stream allows the formation

of the microstructure of hypereutectic silumins. A wide range of solidification temperature of hypereutectic silumins increases the

potential impact of changes in the cooling rate on a size, a number and a morphology of preeutectic silicon and eutectic α+β (Al+Si).

The paper presents the results of the crystallization process of silumin by the TDA thermographic method and the results of the cast

microstructure obtained in the sampler TDA-10, that was cooling down in ambient air. The study was conducted for silumin AlSi11

unmodified. The work demonstrated that the use of thermal imaging camera allows for the measurement and recording the solidification

process of silumin. Thermal curve was registered with the infrared camera and derivative curve that was calculated on the base of thermal

curve have both a very similar shape to adequate them TDA curves obtained from measurements using a thermocouple. Test results by

TDA thermographic method enable quantitative analysis of the kinetics of the cooling and solidification process of neareutectic silumin.

The work is a continuation of research concerning the influence of intensive cooling of permanent mold in order to increase the casting

efficiency of aluminium alloys using the multipoint water mist cooling system. The paper presents results of investigation of crystallization

process and microstructure of synthetic hypereutectic alloys: AlSi15 and AlSi19. Casts were made in permanent mold cooled with water

mist stream. The study was conducted for unmodified silumins on the research station allowing the cooling of the special permanent probe

using a program of computer control. Furthermore the study used a thermal imaging camera to analyze the solidification process of

hypereutectic silumins. The study demonstrated that the use of mold cooled with water mist stream allows in wide range the formation of

the microstructure of hypereutectic silumins. It leads to higher homogeneity of microstructure and refinement of crystallizing phases and

also it increases subsequently the mechanical properties of casting.
