Description
Summary:The results of experimental evaluation of the properties of cast intermetallic compounds (ICs) and alloys with a high IC concentration of the Ti-Fe, Ti-Ni and Ti-Cu metallic systems indicate that they are highly brittle. Attempts to estimate the ductility of the ICs on the basis of the value of the impact bend test or bending angle of specimens have given low values. An answer was found as a result of investigating the electron structure of the ICs of the Cu-Ti system, which is characterised by the presence of four stable or two unstable ICs at room temperature. Alloying alloys of the Ti-Cu system with other elements changed the nature and type of chemical bonds in the alloys. This improved not only the physicomechanical but also the processing properties.
