“…In order to confirm that, a study of the sub impact on the phase fraction has been performed. The sub fraction was estimated to 46% in the beta transformed area, this is in agreement with results of Attallah et al [13] where 72% of phase were measured by XRD. -processed samples deformed at = 0.75 have higher density and area fraction of needles but, the average widths are similar for -annealed and -processed samples.…”

Mechanical properties of / Ti alloys are improved through complex thermomechanical treatments. In particular, the -forging modifies the -phase precipitation. In this work we investigated the influence of the forging strain on microstructure development and its consequences on mechanical properties. Textures have been measured by neutron and X-ray diffractions. SEM/EBSD investigations and image processing have been used to understand the effect of forging on the -phase precipitation.

“…This alloy is used in the production of the most critical parts and units, such as landing gear, control rods of the leading-and trailing-edge flaps, loaded arms, hydraulic cylinders, and mounting hardware (Kralya et al, 2006). TA19 (Ti-6Al-2Sn-4Zr-2Mo-0.1Si), a near-a titanium alloys (Attallah et al, 2009), has high strength, fine ductile, fine thermal stability and good creep resistance (Feng et al, 2005). The goal of this investigation was to study the tribological behavior and the ball-on-disc sliding wear mechanism about the two different titanium alloys.…”

Purpose -Titanium alloy has the excellent performance and been widely utilized in aeroengine and airframe manufacture. However, improving the understanding of all aspects of titanium alloy is necessary. The purpose of this paper is to investigate the tribological properties of two typical titanium alloys against tungsten carbide under dry friction. Design/methodology/approach -Reciprocating ball-disc friction tests were carried out at room temperature in different loading without lubricant to investigate the friction properties of TA19/WC-Co and TC18/WC-Co friction pairs. The influence of the load on the friction coefficient and friction force was analyzed. The worn surfaces of TA19 and TC18 specimens were observed by the digital microscopy and scanning electron microscopy (SEM). And the wear mechanism was discussed. Findings -The results show that the friction coefficients decreased with the increase in the normal load. However, the reduction in the friction coefficient for the TC18 alloy was less than that for the TA19 alloy. The dynamic friction forces with time were not quite coincident with the variation trend of the friction coefficients during the sliding friction. The results observed by the SEM and EDS revealed that several grooving were the main type of frictional wear causing the surfaces of the TA19 and TC18 alloys. Originality/value -It is shown in the paper that the tribological property of TA19 alloy was better than that of TC18 when sliding against tungsten carbide under the dry friction conditions. The main types of damage to the TA19/WC-Co friction pair were the ploughing, the delamination fatigue associate with abrasive wear and some diffusive wear. The ploughing and abrasion were the main wear mechanisms for the surface of TC18 alloy.
