Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Depending on the exact mix of Nickel-Titanium, ast fixture like this may need to be used. Subscribe to Instron News!

How can we help you? For thinner diameter wire, we recommend using pneumatic cord and yarn grips. By continuing to use our site, you accept our cookie policy.

The second generation Advanced Video Extensometer AVE 2 utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available. For wire with a diameter greater than 0. 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.

This allows hands-free grip operation enabling the specimen to be held with both hands, for easy loading.

ASTM F2516-14 Tensile Testing Nitinol Wire

The accompanying video only shows the final portion of the test. Software for Series Systems. Email addresses must contain the symbol. Accurate strain measurement The weight of a clip-on extensometer may cause bending of the wire, and the knife-edges may slip, damage the wire, or lead to premature failure Secure gripping for varying specimen diameters Accurate turnaround points Instron Solution: Users aatm previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.

ASTM F Tensile Testing of Nitinol Wire – Instron

Glossary of Materials Testing Terms. Nitinol Testing requires a thin strip of the material to be pulled in tension at a specified rate. Pneumatic cord and yarn grips provide selectable clamping force to accommodate different materials and excellent follow-up action which compensates for decay of the holding force due to specimen creep. For example, Nitinol is used in stents, dental wires, catheter guidewires, internal fracture fixation devices, and biopsy forceps.

The challenges of testing Nitinol wire to this standard are: Email addresses can only contain letters, numbers and the following special characters: This article will provide a brief overview of the test as well f251 recommend the perfect grip for a successful tensile test.

Subscribe to Our Newsletters. Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry.

For thicker diameter wire, we recommend using 5kN pneumatic side action grips with serrated faces. There are several types of c2516 that may be used to test Nitinol.

Nitinol, also known as Nickel-Titanium, is a highly elastic metal that also has shape memory. These include the lower plateau strength, upper pleateau strength, and the residual elongation. It is well suited for applications involving plastics, metals, biomedical, composites, elastomers, and more.

Ashm F covers the tension testing of Nitinol which is a material used to make stents in the biomedical industry. Mechanical action wedge grips are the most common fixturehowever other types of grips may be used as well. Onsite Training At Your Facility.
