An apparatus tailored to accurate density measurements of supercooled water, i.e. liquid water in a metastable state below the freezing point temperature, was recently developed at Institute Thermomechanics Czech Academy Sciences. The apparatus, dual-capillary dilatometer, is described, together with measurement procedure and evaluation methodology. primary result method are relative densities ...

The article deals with measurements of linear changes of castings from foliated graphite cast iron and Al-alloys during their solidification. For this purpose the measuring apparatus, which applies a dilatometer of Polish provenience, was built up. Dilatation curves of graphite cast iron and Al-alloys were acquired during the casting process. In the case of Al-alloys the influence of chemical c...
