- Abstract: Bone defects on lower limbs have been treated using a synthetic structure named scaffold [1]. This structure must present interconnected pores with size in the range of 400 to 500 µm, with porosity ideally considered around 55 vol.%. Powder metallurgy coupled with space-holder technique is a simple method that allows control over the porous structure, also allowing the reduction of the scaffolds production costs [2]. The present work has the main objective to produce powder of the Ti-13Nb-13Zr alloy (percentages in weight) from its chips using the hydrate-dehydrate (HDH) method and milling. For this purpose, arc melting was used for Ti-13Nb-13Zr alloy production. Then, the resulting ingot was heattreated at 1000°C by 1 hour and quenched in water. Following the quenching process, the sample was forged in a swage rotary forging, and the cylindrical bar was etched in an acid solution 40 mL of HNO3 and 10 mL of HF. To allow HDH process, alloy chips were produced by machining the cylindrical bar. After that, they were placed in a furnace with a 2 Bar Hydrogen and 900°C for 30 minutes. The hydride chips were milled in a planetary ball mill using balls and jars of WC, a ball-to-powder mass ratio of 5:1, mill rotation velocity 284 rpm for 2 hours, and isopropyl alcohol as the process controlling agent. Finally, the powder was classified by sieves and characterized using DRX and SEM+EDS. Results showed the process feasibility to obtain the Ti-13Nb-13Zr alloy powder from its chips using HDH method. The HDH powders will be used to produce scaffolds by powder metallurgy coupled with space-holder technique. Acknowledgements: The authors wish to acknowled
