Abstract


PENGARUH SOLUTION ANNEALING DAN AGING PADA KAWAT PADUAN SHAPE MEMORY Ni-
Ti DAN Ni-Ti-Cu. Penelitian pengaruh solution annealing dan aging pada paduan shape memory NiTi dan
NiTiCu telah dilakukan. Paduan dalam bentuk kawat dibuat dengan rangkaian proses peleburan vakum,
pengepresan panas, pengerolan panas, penarikan kawat dan perlakuan panas (solution annealing dan aging).
Pengujian yang dilakukan meliputi uji termal DSC, uji XRD dan uji tekuk panas untuk mengukur shape memory
effect (SME). Hasil percobaan menunjukkan bahwa kawat paduan Ni-Ti-Cu (Ni-49,7Ti-9,2Cu) memiliki SME
satu arah yang lebih tinggi dibandingkan dengan kawat Ni-Ti (Ni-48,8Ti) baik pada kondisi solution annealing
maupun aging. Kawat NiTi pada kondisi solution annealing memiliki SME dua arah yang lebih besar dari pada
kawat NiTi pada kondisi aging. Sedangkan pada kawat NiTiCu, kondisi paduan (solution annealing dan aging)
relatif tidak berpengaruh terhadap SME dua arah. Penambahan Cu di dalam paduan Ni-Ti berpengaruh lebih
besar terhadap SME dua arah pada kawat dalam kondisi aging dibandingkan pada kawat dalam kondisi solution
annealing.



Abstract


THE INFLUENCE OF SOLUTION ANNEALING AND AGING ON Ni-Ti AND Ni-Ti-Cu SHAPE
MEMORY ALLOY WIRE. The influence of solution annealing and aging on NiTi and NiTiCu shape memory
alloy has been investigated. The alloys in wire form were fabricated through vacum arc melting, hot pressing,
hot rolling, wire drawing and finally heat treating of solution annealing dan aging). The alloy wire was
characterized by thermal analysis (DSC), XRD and bending-heating test to measure the shape memory effect
(SME). The experimental results showed that the Ni-Ti-Cu wire (Ni-49.7Ti-9.2Cu) exhibited one-way SME
higher than that of the Ni-Ti wire (Ni-48.8Ti) in both conditions of solution annealed and aged. The two-way
SME exhibited by solution annealed NiTi wire was larger than that exhibited by aged NiTi wire. With respect to
NiTiCu wire, the alloy conditions (solution annealed and aged) relatively had no effect on the two-way SME of
the alloy. Finally, it was found that the effect of Cu on two-way SME was larger in the aged Ni-Ti alloy than in
solution annealed Ni-Ti alloy.
