The addition of La to cp-Ti or Ti alloys, like Ti 6Al 4V, leads to the formation of short-breaking chips. Free-machinability is given by elementary La particles in the Ti matrix. The new alloy Ti 6Al 2Fe 1Mo 0.9La 0.5Cu was developed out of the Ti 6Al 4V alloy and exhibits free-machi­nability. However, this alloy offers poor castability due to the formation of hot cracks. Thermocalc® simulations dis­covered that Fe and Cu are broadening the solidification interval of the new alloy, which favors the formation of hot cracks. Therefore, the suitability of other β-stabilizing, like Mn and Cr alloying elements was investigated.

The partitioning of alloying elements between a and b phases was measured at different steps of the isothermal transformation at 710 and 610°C in Ti 17 alloy using EDX analyzer in the TEM. In addition, the transformation crystallography was determined. No differences in substitution elements were observed for a same transformation temperature in the a phase, however the composition varied with the transformation temperature. For the partial transformed specimens, gradient in composition were obtained. Results are compared to calculated compositions using ThermoCalc software and Saunders database.

The article provides the results of a statistical research of the relation of mechanical properties and chemical composition of Ø 15-rolled, forged, and pressed bars made of various modifications of the Ti-6Al-4V titanium alloy. The authors studied the correlation of mechanical properties and the content of alloying elements, impurities, bar diameter, and post-annealing (using various industrial modes) structural parameters, on the basis of the analysis of production data, and established regression dependencies for estimating average values of mechanical properties of bars on aluminum and molybdenum strength equivalents of alloying elements and impurities.
