The most common blade materials are stainless steel and carbon steel . High carbon stainless steel combines the advantages of both stainless and carbon steel. Carbon Steel Blades. An alloy of iron and carbon, carbon steel is the traditional material used for making machete blades.
Not all turbine blades are made of nickel alloy, some blades are made of such family of alloys but clearly not all. Some blades are actually made of ceramic materials. The turbine is always located after combustion chamber and the temperature which the first stage of turbine blades is able to resist is a proof of high technology engine.
Initial material selection for blade applications in Gas Turbine engines included alloys like the Nimonic series alloys in the 1940s. [page needed] The early Nimonic series incorporated γ' Ni 3 (Al,Ti) precipitates in a γ matrix, as well as various metal carbon carbides (e.g. Cr 23 C 6) at the grain boundaries for additional grain boundary
A medium carbon, low alloy steel that hardens well. This steel is ideally suited to blades with a very thick cross section such as tomahawks and axes. Extremely tough and impact resistant, this steel is most often used on blades which are hafted and/or thrown. 55 60
Advancement in material quality in recent years have made ceramics a viable blade material for certain applications. Ceramic blade materials are very hard, equal to RC 75, and offer a low friction coefficient making them ideal for low shock slitting, such as film processing and
Jul 01, 2016 · Although both alloys are very expensive, nickel based alloy particularly Nickel Cr Co Mo Super alloy also known as Rene 41 was chosen because of its excellent corrosion property and high strength at elevated temperature (About 1000°C) which makes it suitable for conventional HP turbine blade application.
A wide spectrum of high performance materials special steels, titanium alloys and superalloys is used for construction of gas turbines. Manufacture of these
Creep is the tendency of a material to slowly change shape when stressed at high temperature. Since no single metal would have all the desired properties, an alloy (a mixture of metals) is used. Very high temperature alloys are called superalloys and are generally nickel , cobalt , or iron based alloys.

For this reason it is essential the right material is chosen. Modern fan blades are made from a single piece of titanium alloy roughly 10kg in mass, 100cm high and 40cm wide. One method used for manufacturing fan blades uses two blade skins shaped from molten titanium in a hot press.

ium is an alloy of iron, oxygen, carbon, and various other materials; titanium benefits from the strength of the material, but it is a little brittle compared to other materials. ium takes a good blade as well as a good surface finish."
Provided is a razor blade material which has excellent high hardness, high strength and high corrosion resistance. The material is made of an Fe base alloy containing, by mass %, not less than 0.5% carbon, 9.0 to 14.0% Cr and from more than zero to 8.0% Mo, wherein precipitates, which can be observed at an optional cross section of the razor blade material, have a diameter of less than 0.1 m.
Nickel Based Superalloys for Advanced Turbine EnginesChemistry, Microstructure, and Properties Tresa M. Pollock University of Michigan, Ann Arbor, Michigan 48109 and Sammy Tin University of Cambridge, Cambridge, England CB2 3QZ, United Kingdom The chemical, physical, and mechanical characteristics of nickel based superalloys are reviewed with
N690 Cobalt Stainless Steel. ManufacturerBohler. N690 or N690Co as it is sometimes called, is a Cobalt enriched stainless steel from Austrian steel company Bohler. N690 shares some similarities with it's other Cobalt steel bretheren such as ATS 55 and VG 10, which are used by Spyder Spyderco in particular has a tendancy to use Cobalt
Rotor blades have historically been made of wood, but because of its sensitivity to moisture and processing costs modern materials such as glass fiber reinforced plastic (GFRP), carbon fiber reinforced plastic (CFRP), steel and aluminum are replacing the traditional wooden units.
However, the material loses some of it's properties at high temperature, so is not used in the hotter parts of the engine (like the turbine blades). Instead these are made from a different type of material known as a superalloy. Compare the difference between this titanium alloy and the structure of a superalloy.
