Description	Materials for bioimplants became more demanding last days, because of increasing number operations and longer life span. Because of that the requirements on the properties of these materials also increases. One of the most promising group of materials for these applications seems to be the beta titanium alloys. Processing of these alloys via arc melting is quite difficult and expensive. That is the reason why the possibilities of other ways of preparation, like powder metallurgy, are studied. In this paper, the influence of cold isostatic pressing (CIP) preparation parameters on biocompatible Ti-Nb alloy properties, were studied. There were used powders with various particle sizes and different sintering parameters and the resulting porosity, chemical and structural homogeneity were observed. Subsequent removing of residual porosity during hot forging was tested on the specimens. After solution treatment alloys were cold swaged and final heat treatment was carried out. Mechanical properties of the final products were measured by tensile tests. The goal of this paper was to determine parameters of final product processing via powder metallurgy so as to obtain material with similar or better properties as materials prepared through arc melting.
