The stress of machine parts for pressure die casting and dies that are in contact with liquid metal influencing their service life
Pressing sleeve Piston Die casting process Heat fatigue Service life Die temperature
2011/3/15
Stress of material surface at die, pressing sleeve and piston in pressure die casting process from liquid alloys is analysed. That is heat fatigue and heat and chemical effect of liquid alloys. The me...
Morphological forms of carbon and their utilizations at formation of iron casting surfaces
Product development Environment protection Lustrous carbon
2011/3/15
Model pyrolysis made possible to identify three solid products of carbonaceous additives. Lustrous carbon is the most important form of the pyrolysis carbon. With its structure and physical and chemic...
The aim of the present study has been designing and putting in operation of a stand for sonic testing equipped with modern and readily available numerical devices and with the author’s own computer pr...
Structural gradient in a thin wall casting of ductile iron
Thin wall ductile iron Structure Gradient
2011/3/11
In this paper a experimental and theoretical structural analysis of thin walled casting made of ductile iron is presented. The work shows that these castings posses a non-homogenous gradient structure...
Thermal analysis of ductile iron in thin walled casting
Thermal analysis Thin wall castings Archimedes spiral
2011/3/11
Hypereutectic ductile iron was cast in self hardening moulding sand to produce castings with the shape of Archimedes spirals and with wall thickness of 1, 2 and 3 mm. Inmould technique was used to pro...
