The cementite particles in the tempered martensite take such dispersion that 10 or more cementite particles having equivalent-circle diameters of 0.02 to less than 0.1 μm are present per one μm2 of the tempered martensite and three or fewer cementite particles having equivalent-circle diameters of 0.1 μm or above are present per one μm2 of the tempered martensite.

    • In a method and a RS (Relay Station) for aggregating service connection identifiers in IEEE 802.16, the RS receives a 1st QoS (Quality of Service) from a 1st MS (Mobile subscriber Station), and stores a 1st SFID/CID (Service Flow Identifier)/CID (Connection Identifier) between a BS (Base Station)-RS corresponding to a 2nd SFID/CID between the RS-MS in table information. The RS receives a DSA-REQ (Dynamic Service Addition Request) including a QoS same as the 1st QoS from a 2nd MS, and sends a DSC-REQ (Dynamic Service Change REQuest) to the BS. Then, the RS receives a DSC-RSP (Dynamic Service Change ReSPonse) from the BS, assigns a 3rd SFID/CID between the RS-MS, and stores a 3rd SFID/CID corresponding to the 1st SFID/CID in the table information. The RS sends a DSA-RSP (Dynamic Service Addition ReSPonse) including 3rd SFID/CID to 2nd MS.
