[ 1 ] - ارزیابی ریزساختاری آلیاژ Ni-Nb-Si در حین فرایند آلیاژسازی مکانیکی
In the present study, the mechanical alloying process was used to produce the Ni-Nb-Si amorphous alloy. X-ray diffraction (XRD)analysis and high-resolution transmission electron microscopy (HRTEM) were used to approve the amorphous phase formation after 12 hours of mechanical alloying. The results obtained from the SEM morphological images of powder particles during mechanical alloying showed t...
[ 2 ] - Heat Treatment Of Cobalt-Base Alloy Surgical Implants With Hydroxyapatite-Bioglass For Surface Bioactivation
ASTM F-75 Cobalt-base alloy castings are widely used for manufacturing orthopedic implants. This alloy needs both homogenization and solutionizing heat treatment after casting, as well as bioactivation of the surface to increase the ability of tissue bonding. In this study, ASTM F-75 Cobalt-base substrate was heat treated at 1220°C for 1 hour in contact with Hydroxyapatite-Bioglass powder in or...
[ 3 ] - Effect of Mold Preheating on the Microstructure of the Investment Cast Astm F-75 Implant Alloy
The ASTM F-75 (Co-28%Cr-6%Mo) is widely used as a biocompatible alloy in medicinefor manufacturing implants. In this study, effect of mold preheating on the as-cast microstructure of thealloy was investigated using the solid investment casting process. Several mold preheating temperaturesof 550, 700, 850 and 1000 °C were selected at the same melt superheat. The samples were characterizedby opti...
