| The preparation of smart alloys for most applications in electronics and medicine is a major challenge, especially for use as dental materials, or spinal and arterial catheters. In this research, the Al-Cu-Mn smart alloy was prepared with a pulsed Neodymium:YAG laser, with maximum energy of 1.6 J and a 10 ns pulse width, using different numbers of pulses and energies. The properties of this alloy were studied with Fourier transform infrared spectroscopy, X-ray fluorescence, X-ray diffraction, and scanning electron microscopy. The three metals, i.e., copper, aluminum, and manganese were mixed in equal weight proportions. The best Al-Cu-Mn alloy was obtained for laser shots with 1300 mJ energy. |
