| description | The necessity of systematic formation of intellectual connections for integration into a single complex of currently fragmented software products for the technological analysis of the castings geometry, thermodynamic modeling of the titanium alloys properties, calculation of molding mixtures thermophysical characteristics for the purpose of conjugate implementation of a set of modeling procedures and casting processes diagnostics of is proved. Lack of such an integrated software package, computer analysis of modeling results in the existing manufacturing products practice demonstrates (by the example of the shrinkage defects distribution in a responsible casting of TL3 alloy) the need for radical technological design tools’ improvement.One of the key components of the “digital technology” being formed in the future is thermodynamic modeling of equilibrium phase transformations, which allows calculating the physico-chemical parameters, thermodynamic, thermophysical and casting parameters of titanium alloys and their evolution in the temperature range of crystallization. Based on thermodynamic simulation, experimental planning apparatus and the experience of statistical analysis carried out, a method for forming models for estimating equilibrium parameters used in modeling foundry processes has been developed, and it shows the possibility of applying it to various casting titanium alloys. For the standard composition of the TL3 alloy, a multifactor system of equations was obtained, reflecting the degree of influence of the components on the fluctuations of the alloy characteristics complex, which determine the development of a series of casting defects. The possibilities of using the obtained models for TL3 alloy and methods of obtaining them for use in computer modeling systems to increase the adequacy and accuracy of the results obtained are described. |
