- Abstract
The work deals with the features of application of promising nanosized particles of TiC, WC, TiB2 for modifying the weld microstructure in aluminium alloy welding. Evaluation of their applicability was performed from the viewpoint of thermodynamic stability in the melts of commercial weldable alloys, which contain: Cu, Fe, Zn, Mn, and Ti. It is shown that despite the relative instability, nanosized TiC particles can be used with success as modifiers of aluminium alloys of Al-Mg system. Here, the presence of silicon limits the titanium carbide resistance in the aluminium melt and, therefore, is undesirable, whereas titanium, contrarily, improves the stability of TiC particles. WC particles can be used with success for modifying the structure of alloys of Al-Si system, the presence of silicon increasing their stability in the melt. Particles of titanium diboride TiB2 are the most stable compound of the studied ones. Its small modifying effect on aluminium alloys is compensated by its stability in aluminium melts at overheating.
