The physical properties of the titanium plate

The hardness of the highest quality of industrial pure titanium is generally less than 120 (brinell), and other industrial pure titanium hardness is 200-295 (brinell).The hardness of pure titanium castings is 200-220 (brinell).Titanium alloy under annealing conditions of hardness value is 32 to 38 (calibration) rockwell C, equivalent to 298-349 brinell hardness.As-cast al Ti - 5-2.5 Sn and Ti - 6 al4v hardness is 320 (brinell), Ti 6 al - low void impurities 4 v casting hardness is 310 (brinell).
Titanium plate elastic modulus:
Of industrial pure titanium tensile elastic modulus is 105-109 gpa. Most of the titanium alloy in the back fire conditions of tensile modulus of elasticity, 110-120 gpa.Age hardening of titanium alloy was a little higher than in the annealed condition has tensile elastic modulus, elastic modulus is equal to the resistance may be greater than a stretch elastic modulus.Although the strength of the titanium and titanium alloy is higher than aluminium and aluminium alloy many, but only 55% of the stiffness.Than the elastic modulus of titanium alloy and aluminum alloy flat, after beryllium and molybdenum and some high temperature alloys.The change of industrial pure titanium or shear modulus for 46 gpa.The shear modulus of titanium alloy for 43-51 gpa.
Titanium plate fracture toughness and impact toughness:
Based on types and conditions of titanium alloy, pure titanium charpy notched impact strength of the value of 15 to 54 j/m3, the state of the forging is about 4 to 10 j/m3.The impact strength of titanium alloy in the annealing conditions for 13-25.8 J/m3, less limitation conditions.Forging condition of al Ti - 5-2.5 Sn charpy v-notch impact strength is 10 j/m3, T1-6, 4 V for 20-23 j/m3.The lower the oxygen content of titanium alloy, this value is higher.Many titanium alloy has the very high fracture toughness, perhaps say titanium crack expanding excellent talents.Annealing conditions of Ti - 6 a1-4 v. when, lack of concentration factor/C = 25.4 mm, the notch tensile strength and the notch tensile strength is greater than 1.The strength of the advances in titanium alloy, add the void content of give alloy shock function whammy impact and fracture toughness.
Under normal atmospheric atmosphere, the endurance limit of titanium and titanium alloy processing and annealing is about 50% - 50% of the tensile strength, the gap condition (3.9) 10000000 times fatigue experiments when annealed Ti 6 al 4 v the endurance limit of 20% of the tensile strength.
The strength of the titanium and titanium alloy are divided into tensile strength, bending strength, shear strength and bearing strength.
Tensile strength, the tensile strength of pure titanium is 265-353 mpa, usually titanium alloy is 686-1176 mpa, the most Xie up to 1764 mpa.Titanium alloy with a lot of appropriate strength of steel, but is much better than the intensity of titanium alloy.
Shear strength, shear strength in the titanium and titanium alloy are usually the tensile strength of 60% 70%.
Bearing strength: titanium and titanium alloy sheet strength of confined to about 0.2 to 2.0 times that of the tensile strength.
Tightening strength: titanium and titanium alloy tightening strength is not lower than the tensile strength.Tightening of industrial pure titanium roughly equal yield strength and tensile yield strength, and Ti 6 al 4 v and Ti - 5-2.5 Sn tightening strength was a little higher than the tensile strength.
