What material is used in aircraft engines?
Aluminium, titanium, and nickel base alloys are mostly and widely used for aircraft jet engine con-struction. A proper evaluation of its microstructure is important from working safety point of view. To receive a well prepared sample of microstructure, some important steps have to be undertaken. The different parts that make up your car’s engine consist of: the engine block (cylinder block), combustion chamber, cylinder head, pistons, crankshaft, camshaft, timing chain, valve train, valves, rocker’s arms, pushrods/lifters, fuel injectors, and spark plugs.However, the main materials used for engine parts are iron base alloys such as structural steels, stainless steels, iron base sintered metals, and cast iron and aluminum alloy parts for the piston, cylinder head and cylinder block.
What is an airplane engine made of?
Current jet engines predominantly use alloys containing nickel and aluminium, which form a strong cuboidal lattice. Within and around this brick-like structure are up to eight other components that form a ‘mortar’. Together, the components give the material its superior qualities. Turbine Jet Engines contain large quantities of high value elements such as Gold, Palladium, Platinum, Nickel, Cobalt, Titanium and high grade Stainless Steel. These elements sit alongside rare-earth elements and iron.
Is titanium used in engines?
Titanium is used in engine applications such as rotors, compressor blades, hydraulic system components, and nacelles. Titanium 6AL-4V alloy accounts for almost 50% of all alloys used in aircraft applications. Jet engine and airframe parts need to withstand temperatures from subzero to 600 degrees Celsius, making titanium’s high temperature performance ideal. Engines parts manufactured from titanium include discs, blades, shafts and casings for the front fan to the rear end of the engine.
