- Abstract
In this paper, the attenuation coefficients of X-rays for a range of voltages (20-35) kV were studied for copper-based alloys (Cu + 0.05 AL + 0.03 Ti) according to the order (A1,A2,A3,A4,A5),by adding percentages of silver (X=1,2,3,4,5)% with two particle sizes (Nano) and (Micro) to the alloy (Cu92-x +5%Al +3%Ti+ Ag x) according to the orders (B1,B2,B3,B4,B5) and (C1,C2,C3,C4,C5) All alloys were sintered at (9000C) for a period of (4) hours. The results showed a direct relationship between the attenuation coefficient and the compression pressure. At the operating voltage (20Kv), the linear attenuation was increased (53.6%) and the mass attenuation was (53.8%), the hardness increased by (45%) and the porosity decreased by (18%) when comparing the results of Alloy (A1). with (A5), respectively, and it was also found that the relationship is direct between the attenuation coefficient and the percentages of silver addition, as it was noticed that the linear and mass attenuation coefficients increased by (34.5%) (34%) when comparing the results of (B1) with (B5), respectively, and the increase is By (33.9%) (33.5%) when comparing the results of (C1) alloys with (C5), the hardness has increased by (33.4%) (32.2%) when comparing the average values of alloy results from (B1) to (B5) and alloys from (C1) to (C5) and the porosity decreased by (37.6%) (31%), respectively. The attenuation coefficient is inversely proportional to the operating voltage, as it decreased by (20%) when comparing the results of voltages (20Kv) with (35Kv) for alloy (B5) and decreased by (26.4%) for alloy (C5).
