1. Evolución Microestructural en Uniones de la Aleación Ti-6Al-4V Mediante el Proceso de Soldadura de Punto por Fricción-agitación
Abstract Friction stir spot welding (FSSW) is a process of recent development and interest, mainly in titanium alloys, since there are previous studies of aluminum alloys, magnesium, steel and polymers. Titanium alloys have a wide range of applications in the aeronautical industry, mainly in the components of commercial aircrafts as landing gear. Therefore,

2. Matrix consolidation mechanism in 1D-Ti/SiC/C composites produced by continuous binder-powder coating
In this workmatrix consolidation mechanism has been investigated in 1D-Ti/SiC/C composites produced by Continuous Binder-Powder Coating - CBPC. Titanium metal matrix composites reinforced with continuous SiC/C filaments were analysed in different densification conditions. The results show that during processing, densification occurs by several mechanisms inc

3. Microstructural characterization of Ti-6Al-7Nb alloy after severe plastic deformation
The ASTM F1295/Ti-6Al-7Nb alloy present mechanical properties and biocompatibility very attractive for application in medical and dental implants. In this context, processing of these Ti-based alloys by severe plastic deformation (SPD) has been extensively reported recently. However, the mechanical properties of equal channel angular pressed (ECAP) ASTM F129

4. Metallographic analysis of the internal microstructure of orthodontic mini-implants
Effective orthodontic anchorage may be obtained by miniimplants inserted into the maxillary bones. However, the risk of miniimplant failure is one of the most important issues, especially the rupture of its structure referred to as fracture, mainly due to metal deficiencies. This study analyzed the internal microstructure of orthodontic mini-implants, ascert

5. Deformation and fracture of an alpha/beta titanium alloy
Titanium alloys are used in the aero-spatial, energy and biomaterial industries among others and exhibit high specific strength and fracture toughness. Their mechanical properties show a strong dependence on the microstructure, especially on the size and morphology of the constituent phases. An experimental evaluation was done to a better understanding of th

7. Mecano-síntese e caracterização de ligas de Ti-Nb-Sn
Mechanical alloying is a powder processing technique involving cold welding, fracturing mechanisms and rewelding of powder particles in a ball mill. The present work applied this technique with the purpose of processing titanium, niobium and tin alloys, through planetary ball mill and attritor mill. The atomic percentages of these elements were varied in six

8. Production of a low young modulus titanium alloy by powder metallurgy
Titanium alloys have several advantages over ferrous and non-ferrous metallic materials, such as high strengthto-weight ratio and excellent corrosion resistance. A blended elemental titanium powder metallurgy process has been developed to offer low cost commercial products. The process employs hydride-dehydride (HDH) powders as raw material. In this work, re

9. Purification and properties of methyl coenzyme M methylreductase from acetate-grown Methanosarcina thermophila.
Methyl coenzyme M methylreductase from acetate-grown Methanosarcina thermophila TM-1 was purified 16-fold from a cell extract to apparent homogeneity as determined by native polyacrylamide gel electrophoresis. Ninety-four percent of the methylreductase activity was recovered in the soluble fraction of cell extracts. The estimated native molecular weight of t
