環形鍛件激光表面淬火的熱處理方法的特征在于局部，即使是形狀復雜的部分，也只是作為耐磨損性所需的部分選擇性地硬化，與過去的方法可以得到比同等程度或更高的硬度進行比較?，F在，激光加工，切割，鉆孔中心是人氣。更少的應用程序熱處理。但是，如果是本機的輸出功率，即使在同一臺機器，通過光的研究中，也可以進行熱處理，如果目的開發的機械部件，環形鍛件激光熱處理的場是需要在未來發展。

　　The characteristics of heat forging processing method of laser surface hardening is local, even in the complex form, is selectively required as part of the wear resistance of the hardened, and the past can be obtained than the same degree or higher hardness compared. Now, the laser processing, cutting, drilling center is popular. Fewer applications heat treatment. However, if the output power of this machine, even on the same machine, by the light of the study, can also carry out heat treatment, if the development of mechanical parts, forging laser heat treatment is needed in the future development.

　　一方面，可以通過研究發現了許多重大的問題。激光熱處理的鍛造變形很少，例如，盡管這一點，通過X射線測定所測定仍具有殘余應力和殘余奧氏體的極大值，可以將其攜帶的尺寸變化的材料的限制。此外，像見'剛度分布，淬火硬度顯著的部分和空白的變化。使用;也有可能剝離現象。我們認為，分區和輕填充激光熱處理部的未來鍛件，仍調查中的實際的材料和動態機械性能的影響方面的潛在回火問題。

　　On the one hand, many important problems can be found through research. The forging of laser heat treatment deformation is very few, for example, in spite of this, the X ray determination determination of residual stress is the maximum force and residual austenite, can be the size change of its carrying materials limited. In addition, like see 'stiffness distribution, quenching hardness, significant parts and blank changes. Use; also possible peeling phenomenon. We suggest that the partitioning and light filling of future forgings in the laser heat treatment section are still investigated in terms of the actual material and dynamic mechanical properties in terms of the potential tempering problem.
