  7. Harden is a small lunar impact crater that lies in the eastern part of the interior floor of the walled plain Mendeleev. It is located on the far side of the Moon, and cannot been seen from the Earth.
  8. (Hardening (botany)) Hardening in botany is the process by which an individual plant becomes tolerant to the effects of freezing during a period of weeks to months. It is a three stage process. ...
  9. (Hardening (computing)) In computing, hardening is usually the process of securing a system by reducing its surface of vulnerability. A system has a larger vulnerability surface the more that it does; in principle a single-function system is more secure than a multipurpose one. ...
  10. (Hardening (metallurgy)) Hardening is a metallurgical and metalworking process used to increase the hardness of a metal. The hardness of a metal is directly proportional to the uniaxial yield stress at the location of the imposed strain. ...
  11. To become hard; To make something hard(er); To become or make a person or thing resistant or less sensitive
  12. (Hardened) Pertaining to the condition of a facility with protective features that enable it to withstand destructive forces, such as explosions, natural disasters, or ionizing radiation.
  13. (Hardened) Steel can be made to have different characteristics by various heat treating processes. These involve heating steel to various temperatures, then cooling it down either rapidly or gradually. ...
  14. (Hardened) off – gradually introduced to a new environment.
  15. (Hardening) Any process of increasing hardness of metal by suitable treatment, usually involving heating and cooling.
  16. (Hardening) The process of heating and cooling a steel to increase the hardness, also known as heat treating. Depending on the grade of steel, hardening can include age hardening, case hardening, flame hardening, induction hardening, precipitation hardening and quench hardening.
  17. (Hardening) the process of taking a soft die, transfer roll, or plate and making it metallurgically hard.  In the process of producing engraved stamps, the design can only be worked into soft steel, but is generally only transferred from hard steel.  The hardening process can be reversed. ...
  18. (Hardening) A heat treatment consisting of heating an alloy to a temperature within or above the critical range, maintaining that temperature for the prescribed time (usually 15-30 min.), then quenching or otherwise rapidly cooling. ...
  19. (Hardening) The term used to describe any of the hot or cold methods of hardening metal. It is frequently followed by tempering. Some metals, like brass, can only be hardened by a cold working operation, while a heat treatment is used for steel. ...
  20. (Hardening) Process of heating parts to a high temperature and then quenching in oil, water, air, or solution.
  21. (HARDENING) Austenitizing and cooling at such speed that in a large part of the work piece a hardness increase occurs through formation of martensite.
  22. (Hardening (Quenching)) Once the forging or stock removal process is completed, a blade is heated to critical temperature (point where the steel is non-magnetic, approx. 1400 degrees depending on the steel) and then cooled quickly in a type of quench medium. ...
  23. (Hardening) (1) Describes a price which is gradually stabilizing; (2) a term indicating a slowly advancing market.
  24. (Hardening) An increase in resistance to indentation.
  25. (Hardening) Heating to high temperature then cooling rapidly in water or brine. Also called quenching. Results in steel that is extremely strong but brittle containing a high degree of internal stresses. ...
