Nature – Brittle intermetallic compound makes ultrastrong low-density steel with large ductility. Although steel has been the workhorse of the automotive industry since the 1920s, the share by weight ...

Density is a characteristic property of a substance. ... Steel. 8.2. PVC. 1.3. Nylon. 1.2. Oak. 0.7–0.9. Pine or poplar. 0.4–0.6. Expected results: Student values for density for each cube will not be ...

But if that same steel is pounded and flattened thin and formed into a big bowl-like shape, the overall volume of the bowl is much greater than the volume of the steel cube. The mass of the steel is ...

The material, known as High-Density Reactive Material (HDRM), is the result of collaboration between ... not volume which is significant considering the material offers the same density as steel.

Automakers are tweaking production processes to create a slew of new steels with just the right properties, allowing them to build cars that are both safer and more fuel-efficient.

To give graphene a new dimension, a team of MIT scientists have developed a sponge-like 3D version that has only five percent of the density of steel, yet is ten times as strong.
