1. Evaluation of two-step transformation in Ni-rich titanium-nickel alloys using thermal and internal friction analyses
ABSTRACT The use of Ti-Ni memory alloys covers several fields of application such as medicine, dentistry, actuators, sensors among others. Because of the thermomechanical behavior of these materials, they are an object of continuous studies and their properties are related to the occurrence of thermoelastic martensitic phase transformations. The thermal anal

2. Obtaining and microstructualand mechanical characterization of Ti-Nb-Sn alloys applied as biomaterial / Obtenção, caracterização microestrutural e mecanica de ligas Ti-Nb-Sn aplicadas em implantes ortopedicos
This work deals with preparation, processing and microstructural and mechanical characterization of ß type Ti-Nb-Sn alloys aiming the manufacturing of orthopedic devices for implants. Ti samples containing Nb at levels of 25, 30 and 35 wt % and Sn at levels of 2, 4 and 8 wt % were prepared by arc melting, homogenized at 1000ºC/8 h and plastically deformed

3. Mechanical properties and corrosion resistance of the Ti-35Nb alloys applied as biomaterial / Propriedades mecanicas e de resistencia a corrosão de ligas Ti-35Nb a serem aplicadas como biomaterial
Titanium alloys form the most versatile class of metallic materials used as biomaterials. Among them, one finds the ß ?type alloy, which must soon become the standard metallic materials for orthopedic applications. The aim of this work is to prepare and characterize a type ß ?titanium alloy containing 35 wt.% Nb. Samples of such alloy were rapidly and slow

4. Effect of niobium´s content and the cooling rate on the microstructure and corrosion resistance of the Ti-Nb / Efeito do teor de niobio e da taxa de resfriamento sobre a microestrutura e resistencia a corrosão de ligas Ti-Nb
Pure titanium is used commercially as biomaterial in the manufacture of odontologic and orthopedic prosthesis, due to its high biocompatibility and good corrosion resistance. The use of the pure titanium shows deficiency in mechanical proprieties because the mechanics requests are high. When the mechanic s requests are high, like in the hip s total implant,

5. Microstructure and mechanical characterization of Ti-Cu alloys for dental applications / Caracterização microestrutural e mecanica de ligas Ti-Cu para aplicações odontologicas
Due to characteristics like high strength-to-weight ratio, high biocompatibility, enhanced corrosion resistance and the possibility of controlling elastic behavior by proper addition of alloying elements, the use of titanium by medical and dental industries is continuously growing. In this work, Ti-Cu alloys with a Cu content varying from 5% to 15 wt% were p

7. Comparative study of two cp Ti casting methods. / "Estudo comparativo de dois métodos utilizados na fundição de titânio cp"
Along the last decade, several jobs have been highlighting the advantages of titanium and titanium alloys and studied the possible utilization for removable partial dentures (RPD) metal frameworks confection. Although advantages, the cast process still presents problems, limiting the titanium use. The objective of this study was to evaluate the influence of
