激光淬火零件内部温度及硬化层深度的近似计算

Approximate Calculation on Case Dapth and Inside Temperature for Laser Hardening Parts

采用非稳态瞬时热源解法，导出了描述激光淬火时零件内部热循环过程及快速估算硬化层深度的近似公式，简便实用，精度较好。

By heat source's solution of unstable heat conduction, the article presents the approximate calculations which can describe the thermal circulation of inside temperature of laser hardening parts and fast evaluate the case depth. The precision is acceptable.
