These include the lower plateau strength, upper pleateau strength, and the residual elongation.
For thinner diameter wire, we recommend using pneumatic cord and yarn grips. Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.
Onsite Training At Your Facility. For thicker diameter wire, we recommend using 5kN pneumatic side action grips with serrated faces.
axtm The AutoX is a high-resolution, long-travel automatic contacting extensometer. Subscribe to Instron News! Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry. The F procedure involves tensioning the sample initially and then bringing it back down. A specially designed horn with a smooth finish and a contoured surface with a graduated cam allows for easy loading and a stress f25116 clamping area on the specimen.
