Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry. Email addresses can only contain letters, numbers and the following special characters: Nitinol, also known as Nickel-Titanium, is a highly elastic metal that also has shape memory. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Software for Series Systems.
The F procedure involves tensioning the sample astk and then bringing asttm back down. How can we help you? Subscribe to Instron News! These unique properties make it very useful in a host of other applications including kidney stone retrieval baskets, eye glass frames, and micro antennas.
For example, Nitinol is used in stents, dental wires, catheter guidewires, internal fracture fixation devices, and biopsy forceps. Onsite Training At Your Facility. Contact Us View Accessories Catalog. It is well suited for applications involving plastics, metals, biomedical, composites, elastomers, and more. These include the lower plateau strength, upper pleateau strength, and the residual elongation.
The clamping mechanism can be activated either automatically or through a foot switch. There are several types of grips that may be used to test Nitinol. By continuing to use our site, you accept our cookie policy. The AutoX is a high-resolution, ff2516 automatic contacting extensometer. After that initial flexion the specimen is then pulled again until failure.
A specially designed horn with a smooth finish and a contoured surface with a graduated cam allows for easy loading and a stress reduced clamping area on the specimen. Pneumatic cord and yarn grips provide a convenient method for clamping fiber, cord, yarns and fine wires to reduce the problem associated with testing these materials. Both the AVE 2 and AutoX are capable of measuring strain in cyclic loading and to failure without damaging the Nitinol wire.
ASTM F – 07 Standard Test Method for Tension Testing of Nickel-Titanium Superelastic Materials
The challenges of testing Nitinol wire to this standard are: For thinner diameter wire, we recommend using pneumatic cord and yarn grips. Nitinol Testing requires a thin strip of the material to be d2516 in tension at a specified rate.
Depending on the exact mix of Nickel-Titanium, a fixture like this may need to be used.
The second generation Advanced Video Extensometer AVE 2 utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available.
Glossary of Materials Testing Terms. For thicker diameter wire, we recommend using 5kN pneumatic side action grips with serrated faces. Accurate strain measurement The weight of a clip-on extensometer may cause bending of the wire, wstm the knife-edges may slip, damage the wire, or lead to premature failure Secure gripping for varying specimen diameters Accurate aetm points Instron Solution: Check this ashm to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!
They are designed with standard and optional features that increase testing efficiency and improve the testing experience for qstm operator. Please confirm that you agree with our privacy and cookies policy to submit this form. Mechanical action wedge grips are the most common fixturehowever other types of grips may be used as well.
Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. WaveMatrix 2 for Dynamic Testing. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.
For wire with a diameter greater than 0. This allows hands-free grip operation enabling the specimen to be held with both hands, for easy loading. We use cookies to improve your browsing experience. Next Checking to see if you are a returning visitor….
In the video we demonstrate a special type of tension fixture that is most commonly used for testing wire. The d2516 video only shows the final portion of the test.
ASTM F2516-14 Tensile Testing Nitinol Wire
Bluehill LE for Basic Testing. ASTM F covers the tension testing of Nitinol which is a material used to make stents in the biomedical industry.
