    The influence of physical and chemical parameters of modified water glass on the strength of loose self-setting sands with water glass
    (2012) Kmita, Angelika; Hutera, Barbara
    An attempt of water glass modifying by 30% water bochmite Al(OH)O solution was undertaken. The flow curves were determined and the binder viscosity estimated from them. The quartz wettability by binders was determined by measuring the wetting angle θ changes with time. Strength properties of moulding sands with fractions of modified binders were verified by checking the tensile strength R$_m^u$ after various hardening times under environmental conditions. The R$_m^u$ value after 24 h of hardening was assumed for the analysis.

    Thixoforming of high-melting-point alloys
    (Wydawnictwa AGH, 2017) Sołek, Krzysztof
    Processing of steel in the semi-solid state concerns mainly continuous casting and thixoforming processes. Continuous casting is usually applied within the confines of steel making processes. Due to stringent process requirements, thixotropic forming of steel alloys has not been practically applied in industry yet. However, it is believed that this method could be used for forming selected products. Thixoforming could be treated as alternative method of production for forging techniques in the case non-plastic alloys. In this paper the method of development of globular microstructure, thixoforming process and analysis of rheological properties of selected steels were described.
