[SD] Strong, Tough and Now Cheap: New Way to Process Metallic Glass Developed

ScienceDaily (May 13, 2011) — Stronger than steel or titanium -- and just as tough -- metallic glass is an ideal material for everything from cell-phone cases to aircraft parts. Now, researchers at the California Institute of Technology (Caltech) have developed a new technique that allows them to make metallic-glass parts utilizing the same inexpensive processes used to produce plastic parts. With this new method, they can heat a piece of metallic glass at a rate of a million degrees per second and then mold it into any shape in just a few milliseconds.

Velly nice.

Awesome. I wonder what the difference between a part made in plastic and a part made with metallic glass would be.

I hope the whole process (materials and energy, and the waste when the product is eventually garbaged) that goes into this is more eco-friendly than the production of plastic material.

I really hope we get into the recycling of metals more, this could be useful for a lot of situations.

I am not sure where they are going with this, but this is mostly all wording overhype.
Strong=tough I'd just like to mention.

Metals are known to have bi polar characteristics. You can get tough metals, or hard metals. There is no such as a tough and hard material.

For example steel can be heat treated then rapidly cooled to produce martensite, in other words a metallurgical process that hardens steel by forming a crystalline structure.
This causes the steel to be very hard, but very brittle.

Or it can heat treated specially to form bainite, an incredibly tough and shock resistance steel.

It's no secret that steels are not tough, many synthetics can easily surpass steel's toughness.

This is a plastic replacement, not a metal replacement.

Definitely, plastics generate so much waste. I hope this is a good step towards reducing the massive production of plastic products, but of course it's probably going to be around for a very, very long time :/

Not quite. Strong = not easily bent and/or in that way, broken and tough = not easily scratched/shattered

for example, iPhone 4 is strong, it is not tough
