摘要

Addition of Fe to the NiTi can significantly alter the microstructure as well as properties of the shape memory alloys. Ti50Ni50−XFeX (x = 0, 2, 4, 6, 8, and 10, where all composition in at. pct) shape memory alloy was fabricated by powder metallurgy technique followed by investigations by nanoindentation and tribological tests. Homogenized mixture of elemental powders of iron, nickel, and titanium were compacted at 600 MPa for 4 minutes followed by pressureless sintering at 1050 °C to 1150 °C under Ar atmosphere. Analysis revealed that specimen S5 sintered at 1050 °C sample showed better tribological performance, and S2 sample sintered at 1150 °C showed higher elastic recovery ratio (better shape memory behaviour) over other specimens. Abrasive and adhesive wear mechanisms were observed from the worn surface of wear samples.
