Is nickel base alloy a superalloy? The similarities between the two
Is the nickel base alloy the same as the superalloy
Nickel base alloy is a kind of alloy which has high compressive strength of bai and certain oxidation resistance erosion ability at 650~1000 ℃. According to the key characteristics, it is subdivided into nickel based heat-resistant alloy, nickel based corrosion resistant alloy, nickel based wear-resistant alloy, nickel based precision alloy and nickel based deformation memory alloy. Superalloys can be divided into iron base superalloys, nickel base superalloys and cobalt base superalloys according to the different base materials. Among them, nickel base superalloy is generally called nickel base alloy.
GH4169.3128.3044.3030.3039.5188 superalloy still has excellent impact toughness and the ability to maintain the surface properties without decreasing in the high-temperature natural environment above 780 ℃. This is because superalloys have high tensile strength, stress relaxation cracking compressive strength, excellent plasticity and ductility, and excellent oxidation resistance and high temperature corrosion resistance.
