Effect of Cold Drawing & Heat Treating on Powder-Metallurgy Processed ASTM F 1537 Alloy 1 and Alloy 2 Barstock

摘要

ASTM Standard F 1537 provides the chemical, mechanical, and metallurgical property requirements for barstock produced from three grades of cobalt alloys containing 28 percent chromium and 6 percent molybdenum. The barstock is subsequently forged and I or machined to produce medical implant components such as femoral stems, femoral heads, acetabular cups, fixation screws, and pins. Alloy 1 and Alloy 2 referenced in this standard are respectively low-carbon (LC) and high-carbon (HC) alloys. Barstock made from these alloys can be produced by either cast I wrought, or powder metallurgy (P/M) processing.
