Characterization of complex Al60Cu20Ni15Ti5 alloy produced by mechanical alloying and sintering
vol. 58 (2020), no. 5, pp. 331 - 339

In this work, microstructural and thermal properties of the mechanically alloyed complex Al60Cu20Ni15Ti5 alloy have been investigated by a combination of differential thermal analysis (DTA), X-ray diffraction (XRD), and scanning electron microscope with energy dispersive X-ray detection (SEM/EDX). The results showed that the new Al60Cu20Ni15Ti5 alloy in metastable multiphase formation was produced by milling for 50 h. As the milling time increased from 50 h to 100 h, more homogeneous structure and intermetallic phases such as Al3Ni and Al2Cu were observed, and also grain size decreased. Besides, the maximum microhardness value in pressed and sintered alloy samples was found to be 560 HV.
