Key to making stronger metal discovered

Researchers at Lawrence Livermore National Laboratory have discovered that the number three is the key to creating a strong piece of metal. It’s common knowledge that metals such as steel are strengthened when they’re hammered. What wasn’t known was the full reason behind it. Metal dislocation was discovered in the 1930’s and research has been focused on discovering what this affect had on metal. It appears now that 3 dislocations in a piece of metal is the key to strength. This knowledege will prove useful in engineering stronger structures such as high rises, bridges and other key structures. This once again proves the old biblical adage that “a three strand chord is not easily broken.” Here is some good metallurgical reading at Science Daily with links to the full story.
