NDC fabricates Nitinol products from wire, sheet, strip, tubing, and bar

Nitinol Devices and Components (NDC), Fremont, Calif., offers a wide range of materials in wire, strip, sheet, tubing, and bar form. It was the first company to process laser-cut, self-expanding stents for the medical device industry, and pioneered electropolishing techniques to achieve biocompatible surfaces for medical implants. Its materials meet ASTM standards and reportedly have the lowest carbon content and the tightest tolerances in the industry.

First Nitinol-based large joint fusion device reaches 100 implantations in limited launch

MedShape Inc., Atlanta, reports that during its targeted soft launch period, DynaNail has been successfully implanted in over 100 tibiotalocalcaneal (TTC) fusion procedures. Because the internal nickel titanium (Nitinol) element maintains the target fusion bones in close apposition and under sustained compression, fusions are being observed with the DynaNail TTC Fusion System in high-risk patients, specifically those who require bone allografts.

Nanoscale shape-memory bismuth oxide activated by electric field provides recoverable strain of 14%

A research team at Lawrence Berkeley National Laboratory, Calif., has discovered a way to introduce a recoverable strain into bismuth ferrite of up to 14% on the nanoscale, larger than any shape-memory effect observed in a metal. Bismuth ferrite is a multiferroic compound comprised of bismuth, iron, and oxygen. It displays both ferroelectric and ferromagnetic properties, meaning it will respond to the application of external electric or magnetic fields.

Metlab hardens and press-quenches leaf springs for 1932 Alfa Romeo

Metlab, Philadelphia, recently heat-treated custom fabricated leaf springs of an antique 1932 Alfa Romeo sports car. The springs were made for a Pennsylvania-based automobile restorer. The leaf springs, made from HR-5160 steel, were patterned after the original springs, which were too worn to be reused. The replacement springs were hardened and press quenched into the shape of the spring, and were tempered to a final hardness of HRC 28–32, duplicating the hardness as measured on the originals.

NanoSteel weld overlay improves wear rate of concrete slick line by a factor of 30

The NanoSteel Company, Providence, R.I., announces that its Super Hard Steel weld hardfacing alloy has been selected by Trimay Wear Plate Ltd. as cladding within the steel piping of a concrete slick line to provide wear protection at an underground mine in northern Canada. The alloy has been shown to improve wear rate by a factor of 30 over the previous solution. Combined with Trimay’s unique casing design, this project represents the second line of identical configuration for the customer and will be installed during the first quarter of 2014.
