The Thermal Transformation from Austenite to Martensite and the Origin of Shape Memory

In this introduction to the second chapter of Nitinol: The Book, Tom introduces the shape memory effect as it relates to phase transformations in metals. ...continue reading

Phase Transformations in Metals

In Chapter 2 of Nitinol: The Book, Tom introduces some basics principles of phase transformations in metals. As unusual as Nitinol is, the superelastic and shape memory properties driving these are a byproduct of phase transformations that are ubiquitous in virtually all materials. Read on to learn more, including why Napoleon's Russian invasion failed because of a phase transformation... ...continue reading

SMST-2010: The Effect of Material Removal on the Corrosion Resistance of Laser-cut and Wire-form Products

In this SMST-2010 presentation, Jennifer presents data comparing the corrosion and biocompatibility performance of wire formed and laser cut stents having virtually identical starting geometry. Both groups were electropolished to remove <5%, <10%, and <25% material. Results indicate that the corrosion resistance increases with the amount material removal, and less material removal is required for ...continue reading

Introducing NitinolUniversity.com

About two years ago, in May 2008, NDC regained its independence as a privately held company. To celebrate our one year anniversary, in May 2009, we launched a new brand identity and website at www.nitinol.com. This year, for our two year anniversary, we introduce a new feature of the website, NitinolUniversity.com ...continue reading

The Future

What does the future hold for Nitinol? In this chapter, Tom speculates about the potential of shape memory applications, R-phase, and such emerging technologies as thin-film constructs, and porous Nitinol. ...continue reading

A Historical Perspective

The history of steel dates thousands of years to ancient times, stainless steel has been prominent for about a hundred years, and Nitinol for perhaps a couple of decades. In this short chapter, Tom traces the ancestors of modern nickel titanium, dating to the 1930's. ...continue reading
