Effect of inoculation on high temperature plastic properties of the centrifugally cast Cr-Ni-Nb steel
High-temperature mechanical properties Austenitic Cr-Ni-Nb cast steel Centrifugal casting
2008/7/14
From the centrifugally cast sleeve segments, in direction parallel to the axis, the specimens for mechanical tests were cut out in a way such as to get in one batch of the specimens a structure compos...
Determination of the continuous casting cross-section with prescribed average temperature
Solidification Stefan problem Heat equation Continuous casting
2008/7/8
This paper presents the method of determination of the continuous casting cross-section, in which average temperature was equal to a prescribed value. The method proposed here does not require evaluat...

Modelling of semi-liquid aluminium flow in extrusion with temperature effect
Innovative materials and foundry technologies thixoforming
2007/3/12
During thixoforming, when the material is in the semi-liquid state, it exhibits thixotropic properties, i.e. the unsupported material remains stiff and holds its shape so it can be readily handled, bu...
