LIQUID PHASE FABRICATION TECHNOLOGY OF LAYERED Ti/Al COMPOSITE

In this paper, influence of technological parameters of liquid-phase producing of Ti/Al layered composite on its microstructure and mechanical properties were investigated by means of scanning electron microscopy, energy-dispersive spectroscopy, bend and tensile strength measurement. The results of microscopic studies show that the increasing of the gap between the titanium plates, holding time and melt temperature don't affect significantly on the thickness of intermetallics that formed on Ti/Al interface. Bending test results demonstrate good adhesion and high-quality metallurgical bonding between titanium and aluminium. Tensile strength tests identify increasing of the gap from 1 to 1.5 mm having allowed manufacturing a lightweight material with acceptable mechanical properties.
