凰呀

表面硬化

夢里尋花

表面淬火

空余恨

個人理解是表面高硬度，心部高韌性及一定的強度。

問了一個材料專家，答復如下：
7 w! B  `0 x+ kShell hardening means only the surface layer was hardened, the core was not completely to martensite. So, it will have high compressive residual stress on the surface like inductive hardening.
+ Q, k  H# T$ B* L) r6 ZFor example--limited hardenability steel TSH.
