THE SAMPLES EXHIBITED A HOMOGENEOUS SOLID SOLUTION WITH A α-PHASE AND MINOR AMOUNT OF β-PHASE. WITH THE AL CONTENT RISING, THE DENSITY AND VICKERS MICROHARDNESS VALUES DECAYED WHILE THE YOUNG’S MODULUS INCREASED, AS A RESULT OF THE α-PHASE STABILIZATION AND SOLID SOLUTION SOFTENING. THE OBTAINED RESULTS SHOWS THAT THE SAMPLES WITH HIGH AMOUNT OF AL CAN HAVE GREAT POTENTIAL FOR THE USE AS SINGLE-AXIS KNEE PROSTHESES, ONCE IT COMBINES INTERESTING PROPERTIES WITH LOWER COST.
