What materials use aerospace applications?
The most commonly used commercial aerospace structural materials are aluminum alloys, titanium alloys, high-strength steels, and composites, generally accounting for more than 90% of the weight of airframes.
Where is Nitinol used?
Nitinol tubing is commonly used in catheters, stents, and superelastic needles. In colorectal surgery, the material is used in devices for reconnecting the intestine after removing the pathogens.
What metals are in Nitinol?
Nickel titanium, also known as Nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages. Different alloys are named according to the weight percentage of nickel; e.g., Nitinol 55 and Nitinol 60.
Is platinum used in aerospace?
Precious Metals are Extensively Used in Aircraft Engines Platinum and palladium are used because they are stable, corrosion-resistant and durable. You’ll find them and other precious metals in fuel nozzles, heat exchangers, turbine vanes, and elsewhere.
What are the applications for shape memory alloys?
The following is a list of just some of the applications that shape memory alloys have been used for. Bioengineering: v Bones: Broken bones can be mended with shape memory alloys. The alloy plate has a memory transfer temperature that is close to body temperature, and is attached to both ends of the broken bone.
Who is the leader of shape memory alloys?
Dr. Othmane Benafan, a materials research engineer at NASA’s Glenn Research Center in Cleveland, Ohio, and shape memory alloys team leader, says, “By changing temperature to these metals, you can have them push and pull things to do work.
How are shape memory actuators used in space?
Shape memory actuators have been used in space since the 1980s, and NASA’s Mars Pathfinder Sojourner Rover has them. In most cases, they are used for a one-time antenna or cargo deployment, pin-pullers, or other single-actuation devices. Aircraft standards are much more stringent, where the devices must perform millions of cycles.
Can a broken bone be mended with shape memory alloys?
v Bones: Broken bones can be mended with shape memory alloys. The alloy plate has a memory transfer temperature that is close to body temperature, and is attached to both ends of the broken bone.
