Putting An End To Shear Band: New Research Finds A Solution

An international team of researchers from across the globe have been hard at work to figure out how to control the “shear band” defect that occurs in metals during the manufacturing process. Their hard work has led to the discovery of how exactly to control this problem that is faced by many manufacturers today. Many manufacturers have experienced the inconvenience of shear banding, an issue that typically arises during the high speed machining of metals commonly used throughout the ...

Watching alloys change from liquid to solid could lead to better metals

If you put a camera in the ice machine and watched water turn into ice, the process would look simple. But the mechanism behind liquids turning to solids is actually quite complex, and understanding it better could improve design and production of metals. A recent investigation aboard the International Space Station contributed to that understanding. A series of experiments conducted in the Directional Solidification Insert (DSI) of the Device for the study of Critical Liquids and Crystall...

New Titanium-Making Process Could Result in Lighter Aircraft

Titanium is often used where low weight and high strength are required and money is no object—because it's extremely costly to produce. Now, a new manufacturing technique could reduce the expense, and make the material as useful for cars as it is for fighter jets. Titanium is usually made using the Kroll process. It takes refined rutile or ilmenite from the original metal ore, then puts its through a process that sees temperatures reach over 1000 °C while it's treated with chlorine gas, ...
