Taciau net ir is tavo citatos... o njews'istai cia jau virs interneto? :)) .. zodziu, as irgi ta pati.. gugliawike pasinaudojau.. bet rysium su tuo, kad as antistrongines fizikos zinias turiu, tai ir nezinau, ar mano nuojauta citatoms pasiteisins. > ...tvirtas kaip plienas... dvigubai tvirtesnis uz aliumini. > Arba plienas silpnas arba labai jau kietas aliuminis :) > Cia kaip anekdote "dub xujovyj i xuj dubovyj". na vertalas is wiki ko gero: Titanium ***alone*** is a strong, light metal. It is stronger than common, ***low-carbon_steels***, but 45% lighter. It is also twice as strong as *weak* aluminium ***alloys*** but only 60% heavier. http://en.wikipedia.org/wiki/Titanium_alloy#Grades_of_titanium_and_titanium_alloy_seamless_pipe_intended_for_general_corrosion_resisting_and_elevated_temperature_service Grade 5, also known as Ti6Al4V, Ti-6Al-4V or Ti 6-4, is the most commonly used alloy. It has a chemical composition of 6% aluminium, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen, and the remainder titanium.[5] Since it is the most commonly used alloy – over 70% of all alloy grades melted are a sub-grade of Ti6Al4V, its uses span many aerospace airframe and ****engine_component**** uses and also major non-aerospace applications in the marine, offshore and power generation industries in particular."[7] "Applications: Blades, ****discs****, rings, airframes, fasteners, components. Vessels, cases, hubs, forgings. Biomedical implants."[5] Generally, Ti-6Al-4V is used in applications up to 400 degrees Celsius. It has a density of roughly 4420 kg/m3, Young's modulus of 115 GPa, and tensile strength of 1000 MPa.[8] By comparison, annealed type 316 stainless steel has a density of 8000 kg/m3, modulus of 193 GPa, and tensile strength of only 570 MPa.[9] And tempered 6061 aluminium alloy has 2700 kg/m3, 69 GPa, and 310 MPa, respectively.[10] http://en.wikipedia.org/wiki/6061_aluminium_alloy#6061-T6 **** Pliko Ti info is http://en.wikipedia.org/wiki/Titanium : Young's modulus 116 GPa Shear modulus 44 GPa Bulk modulus 110 GPa Poisson ratio 0.32 Mohs hardness 6.0 Vickers hardness 970 MPa Brinell hardness 716 MPa http://en.wikipedia.org/wiki/Aluminium Young's modulus 70 GPa Shear modulus 26 GPa Bulk modulus 76 GPa Poisson ratio 0.35 Mohs hardness 2.75 Vickers hardness 167 MPa Brinell hardness 245 MPa **** Bet kaip lydyniams: http://en.wikipedia.org/wiki/Titanium_alloy vs http://en.wikipedia.org/wiki/Aluminium_alloy
