Penelitian dilakukan untuk mempelajari pengaruh perlakuan pelarutan terhadap sifat mekanik dan stuktur mikro paduan terner Zr-Nb-Mo untuk biomaterial. Paduan zirkonium dapat digunakan sebagai bahan implan. Paduan Zr-5Nb-xMo (x= 0, 1, 3 dan 5 %wt) dilakukan perlakuan pelarutan dengan variasi temperatur 900oC, 950oC dan 1000oC dengan pendinginan cepat menggunakan media air. Hasilnya menunjukan bahwa meningkatnya kandungan molibdenum, meningkatkan fasa β-Zr dan meningkatnya temperatur perlakuan pelarutan dapat meningkatkan kekerasan paduan zirconium. Hal tersebut terjadi karena unsur molibdenum bertidak sebagai beta stabilizer dan perlakuan pelarutan membentuk perubahan bentuk fasa β-Zr dari plate menjadi lath yang lebih halus. Pengujian kekerasan Rockwell C dengan nilai kekerasan tertinggi 53,67 HRC paduan Zr-5Nb-1Mo perlakuan pelarutan 1000oC, fasa yang terbentuk adalah α-Zr, β-Zr, dan intermetalik Mo2Zr paduan Zr-5Nb-5Mo yang diidentifikasi menggunakan X-Ray Diffraction (XRD).
