More Information
Summary:When Q=([Ti]/48+[V]/51+[Zr]/91+[Nb]/93)/([C]/12), the value of the parameter Q is between 0.9 and 1.1. (In the equation, [Ti], [V], [Zr], [Nb], and [C] respectively represents the content of Ti, V, Zr, Nb, and C in mass %.) The parent phase of a metal structure is a ferrite phase and the metal structure does not contain a non-recrystallized structure. The ferrite particles constituting the ferrite phase have an average particle size between 10 [mu]m and 200 [mu]m. Deposits containing at least one element selected from among Ti, V, Zr, and Nb are present in the ferrite particles at a density of 10/[mu]m3 or more. The average particle size of the deposits is between 0.002 [mu]m and 0.2 [mu]m.
