Raul Oliveira de Araújo Araújo, R.O.(UNESP - Universidade Estadual Paulista); Grandini, C.R.(Universidade Estadual Paulista); Recently, many researches were conducted based on metastable beta alloys due to the possibility to change the structure and microstructure and consequently the mechanical properties of these alloys by specific heat treatments. The main goal of this paper is to study the effect on selected mechanical properties like hardness and elastic modulus, annealing heat treatment in Ti-10Mo-xZr (x = 5, 10, 15 and 20 %wt.) alloys. Annealed alloys have a significant alpha phase quantity in beta phase matrix due to slow cooling rate adopted in this processing. The microhardness and elastic modulus behavior are according to structure and microstructure, where beta phase has high microhardness and low elastic modulus values than alpha phase.
