Rough turning of titanium alloy (6Al-4V)
(2012-12-01)
Metal machining is the complex process due the used cutting parameters. In metal cutting process, materials of workpiece differ widely in their ability to deform plastically, to fracture and to sustain tensile stresses. ...
Stacking faults in SiCf/SiC composite obtained by chemical vapor reaction process
(2008-12-01)
SiC fiber-reinforced SiC matrix composite (SiCf/SiC) is one of the leading candidates in ceramic materials for engineering applications due to its unique combination of properties such as high thermal conductivity, high ...
Influence of thermal treatments in the corrosion behaviour of HVOF Cr 3C2-NiCr coatings
(2001-12-01)
Thermal spray coatings as Cr3C2-NiCr obtained by high velocity oxy-fuel spraying (HVOF) are mainly applied due to their behaviour against aggressive erosive-abrasive and corrosive atmospheres and their thermal stability ...
Development and test of resistive superconducting fault current limiter; acting time and its recovery conditions
(Iop Publishing Ltd, 2014-01-01)
Resistive-type of superconducting fault current limiters (RSFCL) have been developed for medium voltage class aiming to operate at 1 MVA power capacity and short time recovery (< 2 s). A RSFCL in form of superconducting ...
Microstructural effects on fatigue crack growth behavior of a microalloyed steel
(2010-04-01)
Thermal transformations on microalloyed steels can produce multiphase microstructures with different amounts of ferrite, martensite, bainite and retained austenite. These different phases, with distinct morphologies, are ...
Friction and wear of performance of MoDTC and ester-containing lubrificants over steel surfaces under reciprocating conditions
(Centro Congressi InternazionaleTorino, 2013)
Since the earliest developments of human history, friction has been a major issue. From the invention of the wheel and the use of the first lubricants to the studiesof coated and microtexturized surfaces, significant effort ...
Effect of testicular thermoregulation on the quality of buffalo sperm
(2013-12-01)
The process of spermatic division and differentiation (spermatogenesis) occurs with intratesticular temperature lower that the corporal temperature and for that is essential that the testicular thermoregulation mechanism ...
Viscosity of fluoroindate glasses
(1998-12-01)
The viscosity of two fluoroindate glasses was measured as a function of temperature in the range of 310 °C - 362 °C. In such interval, the viscosity values were found to be similar to those reported for fluorozirconate ...
Mortar added by tyre rubber residues: Characterisation in fresh and hardened state
(2004-12-01)
Due to the progressive increase of vehicles, the number of used tires is globally one of the serious environmental problems faced now. Therefore, several researches have being developed for its reuse. The use of tires' ...
Scrotal thermography and doppler ultrasonography of the testicular artery of buffaloes subjected to environmental heat stress
(2013-12-01)
The process of spermatic division and differentiation (spermatogenesis) occurs with intratesticular temperature lower that the corporal temperature and for that is essential that the testicular thermoregulation mechanism ...
