Tensile strength of Nickel-iron

In summary, the conversation discusses the tensile strength of Nickel-iron and where to find information on it. It is noted that the strength depends on the level of annealing or cold-working, and resources such as the Nickel Development Institute and MatWeb can be consulted for more information. Additionally, the question of whether the presence of Widmannstätten structure affects the brittleness of nickel-iron is brought up.

Hi! I'm not sure if this is the right place to post this, but what the tensile strength of Nickel-iron, or where would I be able to find it?

Is one referring to Invar? http://www.nickel-alloys.net/invar_nickel_iron_alloy.html

Strength will depend on whether it is annealed (minimum strength) or cold-worked, with strength increasing as a function of cold-work.

One should be able to find information at the Nickel Development Institute (NDI)

or MatWeb, or suppliers

Does the presence of Widmannstätten structure make nickel-iron brittler?
 

1. What is the definition of tensile strength?

Tensile strength is the maximum amount of stress that a material can withstand before breaking or fracturing. It is a measure of a material's ability to resist pulling forces.

2. How is tensile strength measured?

Tensile strength is typically measured by subjecting a sample of the material to a controlled pulling force until it breaks. The maximum force applied to the sample before it breaks is recorded as the tensile strength.

3. What is the tensile strength of nickel-iron?

The tensile strength of nickel-iron can vary depending on the specific alloy and manufacturing process. Generally, it ranges from 50,000 to 150,000 pounds per square inch (psi). However, some special alloys can have tensile strengths up to 300,000 psi.

4. How does the addition of iron affect the tensile strength of nickel?

The addition of iron to nickel can increase its tensile strength. This is because iron has a smaller atomic radius than nickel, which creates a stronger bond between the atoms and makes the material more resistant to pulling forces.

5. What factors can affect the tensile strength of nickel-iron?

The tensile strength of nickel-iron can be affected by various factors such as the composition and purity of the alloy, the manufacturing process, and any heat treatments or surface treatments applied to the material. Additionally, environmental factors such as temperature, humidity, and exposure to corrosive substances can also impact the tensile strength of nickel-iron.
