| Research Abstract |
Thermal microline patterning to realize metal phases drawing on the alloys substrates had been developed. The liquid resin paste including micrometer sized metal particles were solidified as micro patterns by ink jet printing, and the intermetallic compound patterns were created through the heat treatment by electric furnace. In this investigation, microstructure and composite distributions in intermetallics patterns were observed and analyzed systematically. The reaction diffusion between the metal particles and substrate will be considered. Moreover, stress distributions on the metal surface were modulated by the geometric design of the intermetallics patterns. Load dispersion abilities will be discussed through numerical simulations and mechanical tests. The composite lines could be created successfully on the ally substrates to improve mechanical properties.
