Abstract

Language:

The biocompatibility of Cu-Al-Be-Mn quaternary shape memory alloys (SMAs) is critical for their application in medical devices, where toxicity of materials can trigger immune responses. This study aimed to evaluate these SMAs, containing 10-13 %wt. of Al, 0.4-0.6 %wt. of Be, 0.2-0.3 %wt. of Mn, and the remainder copper, through various tests to assess their properties. The alloys were synthesized using ingot methodology in an induction furnace and were subjected to bend tests to evaluate their shape memory effect, along with corrosion tests in Hank's solution (simulated body fluid) and freshwater to understand their corrosion behavior. Additionally, the antibacterial properties were examined using the agar well diffusion method to explore their biocompatibility further. An array of analyses including spectrophotometry for composition, scanning electron microscopy (SEM) before and after corrosion, and energy-dispersive X-ray spectroscopy (EDAX) were employed to provide a comprehensive characterization of the materials. The results underscore the significant potential of Cu-Al-Be-Mn SMAs in biomedical applications, highlighting their favorable properties that could mitigate immune responses in patients.
