Method #1: Recover from Autosave. By default, Word auto-saves a document every 10 minutes (this can be decreased or increased, see below) that it will automatically recover if the document closed due to a malfunction. Word will not auto-save a file that has been closed willingly using the Word close button.
â¢ Is metal one of the hardest material in the world? Yes, they are but the hardest material in the world known to mankind is DIAMOND. â¢ What is the hardest metal? The hardest known metal alloy, and the hardest known metal in general, is a type of carbon steel, Alloy 1090. With a tensile strength of .84 GPa (122,000 psi) and a yield strength of .64 GPa. (67,000 psi), carbon steel is surpassed in hardness only by very hard nonmetals, such as ruby, diamond, or aggregated diamond nanorods.
If you thought the hardest substance on earth was diamond, that was a good, if inaccurate guess. It is technically an aggregated diamond nanorod. It is actually a collection of nano-scale diamonds, and it is the least compressible, hardest substance known to man.
