The graph shows the corrosion resistance of martensitic stainless steels with high hardness. It compares nitrogen alloyed grade (M340 = AISI 440Mod) with the standard grade AISI 440C.
One Minute Mentor: Tempering Temperature and Corrosion Properties
What is Metallic Glass?
Metallic glass is metal whose crystal structure has been changed to an amorphous structure similar to that of glass, and it combines the strength of steel with the formability of plastic.
Making lightweight and strong metal
A Missouri University of Science and Technology, Rolla, researcher and his colleagues have created a lightweight but very strong structural metal that could improve energy efficiency in aerospace, automobile, defense, mobile electronics, and biomedical applications.
Foam metal makes airplanes more than meets the eye (with video)
Imagine an aircraft that could alter its wing shape in midflight and, like a pelican, dive into the water before morphing into a submarine.
Metal foam handles heat better than steel
Researchers at North Carolina State University, Raleigh, have found that novel light-weight composite metal foams (CMFs) are significantly more effective at insulating against high heat than the conventional base metals and alloys that they’re made of, such as steel.
