For designing or engineering a component of spacecraft, the crucial challenge is weight optimization, and it can't come at the expense of component strength or performance. Materialize Manufacturers and engineers come with the unique idea of using titanium metal and its alloys for the aerospace sector to transfer high mechanical loads in structures like satellites.

With optimized design produced through 3D metal Printing, the titanium inserts are generated of the initial weight, with improved properties. It can be used as mounting points to attach devices to spacecraft and satellites. These titanium inserts are highly suitable for heavy loads, lifting a large and heavy structure that means they have to exhibit a great strength-to-weight ratio. It's a part with high specific strength and rigidity but at a minimal weight. The weight reduction will allow the increase of sound equipment to be used in satellites and result in considerable cost savings in each launch.

Besides weight reduction, titanium and its alloys resolved thermo-elastic stress issues with spacecraft designs. As the titanium inserts are installed during the curing process of carbon fiber-resistant polymers, they are focused on thermo-elastic stresses.

Properties of Titanium make it a suitable element for aerospace and aeronautics

1. Density

The new revolution in material science is the use of titanium and its alloys for space programs. There is possibly no other material more closely related to aerospace than titanium and its alloys. This is because it has a density of 4.5g/cm3, and it is about half as heavy as steel or Ni-based alloys; due to this unique property, Titanium yields an excellent strength-to-weight ratio.

Temperature Resistance

The titanium and its alloys in the aerospace industry will be highlighted, including engine, airframe, helicopter, and space applications. Titanium and Ti-alloys are normally chosen for their mechanical properties, temperature resistance, or chemical resistance.

Corrosion Resistance:

Titanium has outstanding corrosion resistance properties. This specific property makes titanium ideal for the spacecraft industry. Conventional Ti-alloys are also used for primary and secondary structures, fasteners, plumbing systems, and in areas where operating temperatures rule out the use of aluminum alloys.

Characteristics of Titanium and its alloys make it suitable for the aerospace industry

The characteristics of titanium and its alloys are grouped according to their metallurgical structure controlled by the heat-treatment and chemical composition.

Commercially pure titanium products are selected for chemical resistance. Impurities in titanium can increase its strength, but corrosion resistance becomes lesser. Ti- alloys are ideal for contact with CFRP due to their low CTE and matched galvanic corrosion properties.

Titanium alloys are selected for their remarkable strength properties, which depend on several heat-treatments such as quench, age hardening, and temper. The most used titanium alloy is Ti6Al4V, due to broad mechanical and corrosion properties.

All classical shaping and forming processes can be used, with wrought products being produced by rolling, forging, extrusion, cast products. Owing to titanium's high similarity for oxygen and other gases, casting and melting processes are carried out under controlled vacuum to prevent infectivity and subsequent property degradation.

Some restriction of using titanium and its alloys

Titanium alloys shall not be used with oxygen partial pressures.

Titanium alloys shall not be machined within spacecraft during flight or ground processing because operations can ignite turnings and cause a fire.

Titanium alloys can be vulnerable to hydrogen-embrittlement and are unsuitable for hydrogenated atmospheres.

The optimized designs using titanium have reduced vulnerability to stresses and improved load distribution, resulting in increased aerospace industry lifetime. With successful research, manufacturers are looking forward to increasing metal components' implementation in aerospace and aeronautics.
