Zusammenfassung:	With regard to an Al content (%) and a Si content (%), a relation of a formula (A) is established, and an average value Y ave defined by a formula (B) regarding hardnesses measured at 100 points or more with a nanoindenter is equal to or more than 40. 0.3 ¤ 0.7 × Si + Al ¤ 1.5 Y ave = £ 180 × X i - 3 - 2 / n ([A1] indicates the Al content (%), [Si] indicates the Si content (%), n indicates a total number of the measuring points of the hardnesses, and X i indicates the hardness (GPa) at the i-th measuring point (i is a natural number equal to or less than n).
