Titanium Powder Metallurgy for Automotive Components

Enhanced fatigue behavior of powder metallurgy Ti–6Al–4V alloy by applying ultrasonic impact treatment

“…Specimens of Ti-6Al-4V alloy used in this study were prepared by means of the following route of the cost-effective blended elemental PM technique [5][6][7][8][24][25][26]. Hydrogenated (3.5 wt% H) Ti powder (the particle size is 100 μm) were mixed with 60Al-40V master alloy powder (the particle size is 40-63 μm) to obtain the required alloy composition.…”

“…Further development of the PM approach was consisted in the use of titanium hydride as a basis of powder mixtures. It was shown that titanium hydride had a positive impact on the final density, and chemical and microstructural homogeneity of PM titanium alloys of different phase compositions [5][6][7][8].…”

Hydrogen sintering of titanium and its alloys

“…These processes include both pressure-assisted (i.e., hot pressing or HIP) as well as press and sinter methods, and have been used to produce a range of products, including titanium alloys [19,[25][26][27][28][29][30][31], sputtering targets [32], decorative titanium products [33], and shape-memory alloys [34]. Since 2000, a significant amount of work regarding vacuum sintering of hydrogenated titanium powder has been reported by Ivasishin et al [3,4,8,17,20,[35][36][37][38]. This work has led to a series of processes developed and commercialized by an Ohiobased company called The Advanced Material Group (ADMA).…”

“…During this process, compacts of hydrogenated titanium, metallic titanium, and/or master alloy powders are sintered under a dynamically controlled hydrogen partial pressure. The use of hydrogenated powder and the presence of hydrogen in solution during sintering has been shown in several studies to significantly improve purity and densification of PM titanium alloys [3][4][5][6][7][8]. However, HSPT differs from other PM processes in that a dynamically controlled hydrogen partial pressure is used to control the hydrogen content within the alloy during sintering.…”

Caracterización mecánica de aleaciones Ti-Nb mediante ensayos de flexión biaxial

“…Uno de los usos más conocidos tiene lugar en el de la biomedicina, por su excelente biocompatibilidad, baja densidad, resistencia a la corrosión y adecuadas propiedades mecánicas [1] . También, en otros campos como en el sector automovilístico [2] o, incluso, en el área de equipamiento deportivo [3] , está siendo ampliamente utilizado, dado que es un material que destaca por su buena relación resistencia frente a peso.Las aleaciones de titanio tipo β son las más versátiles dentro de las aleaciones de titanio. Destacan por su alta resistencia específica y por la interesante combinación de resistencia, tenacidad y resistencia a la fatiga.…”
