...S. V. Sajadifar; H. J. Maier; T. Niendorf; G. G. Yapici This investigation focused on the deformation response and microstructural changes of severely deformed titanium during post-severe plastic deformation tension, at temperatures of 300–600 °C and at strain rates of 0.001–0.1 s −1 . The obtained...

..., grade 1 titanium + 1100 -O aluminum composites. A multifactorial experiment was designed to study the effect of the above factors on the outcome measures ultimate shear strength and ultimate transverse tensile strength. Generalized linear models were used to study the statistical significance of each...

... ranging from 1 μ m to 10 μ m on stainless steel, titanium, and aluminum. The results indicate that the geometrical characteristics of the interference patterns as well as the thermal properties of the substrates determine the quality of the fabricated structures. In particular, the best structures were...

... materials, such as alloying between the hot titanium and steel, or cracking of ceramics. This is avoided with tungsten based anvils because they do not react with titanium at elevated temperature, but the high thermal conductivity is a draw back for penetration. These relationships should be considered when...

Papakonstantinou; Konstantinos Katakalos The aim of this paper was to investigate the tensile and flexural properties of hybrid laminates made with titanium sheets and high modulus carbon fiber composites. Grade II titanium was used, which exhibits great high-temperature performance...

... USB data acquisition devices and simultaneous PID control loops removed stumbling blocks, which had hindered previous researchers. The following processing principals were experimentally observed. 07 03 2008 01 12 2008 09 03 2009 aluminium alloys titanium alloys vanadium...

...D. Kim; M. Ramulu Titanium/graphite hybrid composites ( TiGr ) are a potentially enabling technology which satisfies the low structural weight fraction and long operational lifetime required for the high-speed civil transport. TiGr composites are made of thermoplastic polymer matrix composite plies...

...S. Bernhardt; M. Ramulu; A. S. Kobayashi The low-velocity impact response of a hybrid titanium composite laminate, known as TiGr , was compared to that of graphite/epoxy composite. The TiGr material comprised of two outer plies of titanium foil surrounding a composite core. The composite core...

.... Measurements are made in a seven-layered plate with a base of commercially pure titanium and successive layers containing an increasing proportion of titanium-boride, reaching 85% titanium-boride in the final layer. The compliance method is employed to determine residual stress, where a slot is introduced...
