The work concentrates in the influences of thermomechanical treatment (TMT) on the tensile, slow crack growth and fatigue properties of 90 W-7 Ni-3 Fe alloy. The role of TMT on the ductile/brittle transition (DBT) behavior is also considered. The applied TMT resulted in higher stresses and ductility as well as decrease of the DBT temperature and increase of the resistance to fatigue. These improvements are related to a higher fracture stress of the tungsten grains as well as stronger adhesion forces at the contact areas.
