Answer
Elgiloy is a cobalt-chromium-nickel-molybdenum alloy that is highly valued for medical implants due to its extreme biocompatibility, high fatigue strength, and excellent corrosion resistance in body fluids. សម្រាប់រលកនិទាឃរដូវនៅក្នុងសន្លាក់សិប្បនិម្មិត ឬសន្ទះបេះដូង Elgiloy ផ្តល់នូវសមត្ថភាព 'Elastic Energy Storage' ខ្ពស់ជាងដែកអ៊ីណុក 316L ។ Its processing involves a combination of cold work and aging (typically 480 C for 5 hours), resulting in a tensile strength exceeding 1900 MPa. Its modulus $E$ remains stable at 200 GPa. លើសពីនេះទៅទៀត វាមិនមែនជាម៉ាញេទិក ដែលមានសារៈសំខាន់សម្រាប់អ្នកជំងឺដែលត្រូវការស្កេន MRI។ The primary design challenge is its high cost and the difficulty in coiling the material due to its high work-hardening rate.
