Synthesis of CuTi intermetallic compound by mechanical alloying route
Year: 2025
Type: article
Abstract: A solid phase consisting of two or more metallic or semimetallic elements with well-defined stoichiometry and an ordered structure is called an intermetallic compound (IMC). IMCs are a diverse resource to understand the relationships between atomic structure, physical characteristics, and chemical composition. In this work, elemental powders of Cu and Ti in an equiatomic ratio were mechanically alloyed (MA) to develop the CuTi IMC. After 30 h of milling, the powder was annealed for 2 h at 1000 o C in an Ar atmosphere. In this novel method, Cu and Ti powders are milled in a 1:1 atomic ratio (Cu - 42.96 wt% Ti) for 30 h. The milled powder was then heated to 1000 °C for 2 h in an Ar atmosphere. Analytical methods such as high-resolution transmission electron microscopy (HRTEM), x-ray diffraction (XRD), electron dispersion x-ray spectroscopy (EDXS), scanning electron microscopy (SEM), differential scanning calorimetry, and thermogravimetric analysis (DSC/TGA) were used to verify the synthesis of CuTi. This method effectively produced nanocrystalline CuTi. This study shows that the CuTi IMC may be synthesized from the binary Cu 50 Ti 50 by MA.
