Compound casting is an efficient method for bonding dissimilar metals, in which a dramatic reaction can occur between the melt and solid. The centrifugal process, type of compound casting, was applied to cast Al/Mg bimetals. Magnesium poured at 700°C, with melt-to-solid volume ratios (Vm/Vs) 1.5 3, into preheated hollow aluminum cylinder. preheating temperatures solid part were 320, 400, 450°C,...

Many graphical objects can be represented by swept volumes (including its subset – generalised cylinders) by sweeping 2D or 3D templates along 3D trajectories. In this paper, we present a new approach for constructing swept volumes using image templates. We utilise scalar fields as our underlying data type, and employ volume ray casting techniques for rendering swept volumes in their original s...

Abstract Obtaining a strong bond between aluminum and steel is challenging due to poor wettability melt brittle intermetallic phases forming in the interface. In this research, novel coating method, namely hot dipping of Sn, has been developed treat insert surfaces. Results show that without preheating mold or Sn-coated insert, thin, crack-free, continuous metallurgical bonding layer was achiev...

introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...

Castings of aluminum and plastics are of high importance in the industrial world. They are usually made using permanent metallic moulds for pressure die-castings and injection molding. Die-tools are usually produced from chromium maraging hot work tool steel and are heat treated to hardness between 29 and 48 HRC, 1-3 . Die life is a mayor factor of a die-casting process and it strongly affects ...

Early-age drying (immediately after casting) of mortars and the corresponding plastic shrinkage were studied using bimodal neutron/X-ray computed tomography. This novel, correlative 3D imaging mode enabled studying simultaneously without any source spurious perturbation water migration loss processes together with deformations due to shrinkage. Bimodal opens up new possibilities for dynamic cou...
