Nondendritic solidification would similarly benefit casting fluidity by decreasing the resistance to liquid flow in narrow channels (thin sections).
During the filling, cooling, solidification, and ejection of the product, the following assumptions are introduced for the mathematical model.
Paton Electric Welding Institute has developed and subsequently improved the mathematical model of solidification of cylindrical ingots in electron beam melting in an intermediate container (EBMIC) which makes it possible to determine the distribution of temperatures in the cylindrical ingot at any moment of time and, consequently, the configuration of the liquid pool and of the zone of the solid-liquid state of the metal in relation to the technological parameters of the electron beam melting (process productivity, periodicity of pouring in the melt into the solidification mould and the power of electron beam heating) (3).
Ensuring uniform solidification is pursued in the case of mechanically less stressed parts with small hot spots.
Conference in Modeling Casting, Welding, and Advanced Solidification.
Because the PITDRY solidification system works by absorbing free liquids contained in the drill spoils, the higher the solids content of the material to be disposed, the lower the dosage of the PITDRY reagent required for disposal (clear water requires a dosage of approximately 2 percent PITDRY by weight).
This means that during final solidification of the solder joint, a "soup" forms of molten solder and solidified particles that have a different grain structure than the last solidifying alloy elements.
Signal attenuation (sound absorption) indicates the degree of solidification of the polymer.
The key factor in producing a frozen droplet with a sharp point is the difference between the angle that the solid makes with the solidification front during freezing and the angle that the liquid makes with the front.
Solidification structures - faceted, dendritic, eutectic and peritectic
The gases dissolved during solidification can be caused by hydrogen or nitrogen in the initial liquid or core gas decomposed from the sand core and vented to the liquid, and they play a major role in porosity formation in castings.
Up to now, the research fields of solidification process mainly focused on metal materials and thermosetting resin composites (8), (9).
