Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Subscribe to Instron News! Both the AVE 2 and AutoX are capable of measuring strain in cyclic loading and to failure without damaging ff2516 Nitinol wire.
Nitinol Testing requires a thin strip of the material to be pulled in tension at a specified rate. Nitinol, also known as Nickel-Titanium, is a highly elastic metal that also has shape memory.
WaveMatrix 2 for Dynamic Testing. Please confirm that you agree with our privacy and cookies policy to submit this form. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. For wire with a diameter greater than 0. This article will provide a brief overview of the test as well as recommend the perfect grip for a successful tensile test. Subscribe to Our Newsletters.
The accompanying video only shows the final portion of the test. After that initial flexion the specimen is then pulled again until failure.
ASTM F Tensile Testing of Nitinol Wire – Instron
Concrete, Asphalt and Rock. ASTM F covers the tension testing of Nitinol which is a material used to make stents in the biomedical industry.
There are several types of grips that may be used to test Nitinol. Software for Series Systems. Pneumatic cord and yarn grips provide selectable clamping asfm to accommodate different materials and excellent follow-up action which compensates for decay of the holding force due to specimen creep.
For thicker diameter wire, we recommend using 5kN pneumatic side action grips with serrated faces.
How can we help you? Email addresses must contain the symbol. 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. Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.
Next Checking to see if you are a returning visitor…. Description Literature Contact Us Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry.
Bluehill LE for Basic Testing. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Nitinol is a shape memory, super-elastic alloy that is used extensively in awtm biomedical f5216. This allows hands-free grip operation enabling the specimen to be held with both hands, for easy loading.
In the video we demonstrate a special type of tension fixture that is most commonly used for testing wire. These unique properties make it very useful in a host of other applications including kidney stone retrieval baskets, eye glass frames, and micro antennas.
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. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! Mechanical action wedge grips are the most common fixturehowever other types of grips may be used as well.
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: 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, r2516 lead to premature failure Secure gripping for varying specimen diameters Accurate turnaround points Instron Solution: Contact Us View Accessories Catalog.
