How to use the mechanical and physical properties of titanium in the process of titanium tube and titanium plate
Release time:
2023-03-07
The modulus of elasticity of titanium is relatively low relative to its tensile properties, so a large rebound margin must be considered in the forming and rolling operations. It is precisely because of the low elastic modulus, in order to achieve the same degree of stability, the cross section of titanium parts is slightly larger than the same steel parts.
The mechanical properties and physical properties of titanium in the process of titanium tube and titanium plate:
(1) The modulus of elasticity of titanium is relatively low relative to its tensile properties, so a large rebound margin must be considered in the forming and roller operations. It is precisely because of the low elastic modulus, in order to achieve the same degree of stability, the cross section of titanium parts is slightly larger than the same steel parts.
(2) Titanium is easy to machine, but to consider its biting tendency (larger than stainless steel) and low thermal conductivity, it is necessary to make appropriate improvements to the commonly used machining technology and thread and bearing surface design. At least there must be a rigid machine tool, a sharp tool, a slow speed, a large amount of cutting, and leave room for chip removal. It is also recommended to use a large amount of cooling lubricant.
(3) The thermal expansion coefficient of titanium is 75% of that of carbon steel. Special attention should be paid to the need to combine these two materials in the design and manufacture of the device.
(4) Since titanium is an active metal, when heated to above 600°C, it is easy to combine with oxygen in the air, so it is generally not recommend to use titanium for a long time above this temperature.
