Abstract

The work deals with the controlled gasification of castings from aluminum alloys. In troubled places of castings the thermal nodes that cannot be always fitted with risers and interior shrinkage with negative influence on tightness and the mechanical properties of casting are formed. If a riser cannot be used for eliminating the negative impact then it is possible to use the Probat Fluss Mikro 100 product. The practical part of the work deals with the monitoring of controlled gasification which creates as a result of adding the Probat Fluss Mikro 100 product and titanium hydride in various proportions. Using the Probat Fluss Mikro 100 as nucleating phase and then with the aid of titanium hydride the hydrogen are brought in the melt. With the aid of visual comparison the effect of controlled gasification is evaluated.
