hardening
Description:
Hardening is the process of increasing the mechanical Resistance of Steel in a targeted manner by changing its structure. Hardening is a production process that modifies Material properties. Various methods are used. Steel properties can be modified using, for example: Transformation (quench) hardening through heating and rapid cooling, which ensures that far more Carbon remains bound than without hardening. During the heating process, ferrite is converted into austenite, in which more carbon can be separated from the cementite that is also present. During subsequent quenching, there is no segregation Strain hardening during Forming, above all with non-ferrous metal alloys. In this case, a changed dislocation density in the structure prevents slippage in the crystal lattice (for example during Rolling or drawing). Hardening with laser or electron beams.

Example sentences:
- The model is subsequently hardened in a hardening cabinet until it reaches its final strength.
- The high cold hardening coefficient enables uniform shaping and prevents cracks.
- Fastening systems which function using the principle of hardening plastic resins to provide stress-free anchoring (no high forces are exerted on the surrounding concrete).
硬化
Description:
硬化是通过改变材料结构来有针对性地增加钢的机械阻力的过程。硬化是一种的生产工艺。 可以使用各种方法。钢的性能可以通过以下方式来改变： 相变硬化 （淬火） ，通过加热和快速冷却，确保比不硬化情况保留更多碳键。在加热过程中，铁素体转变成奥氏体，其间多数碳可以从共存的渗碳体中分离出来。随后的淬火过程中不发生离析；碳使得形成的马氏体原子晶格韧化 （硬化）。为了相变硬化的发生，低碳含量的钢 （小于 0.2％） 必须首先进行渗碳处理，即富集碳处理。 应变硬化首先发生在有色金属合金的成型过程中。在这种情况下，其结构的位错密度改变可以防止在晶格中发生滑移（例如或过程中)。 用激光或电子束进行硬化。 近义词 相变硬化
