摘要： Provided is a steel member which is obtained using a thick steel plate and in which the inner zone (thicknesswise central zone) of the steel material exhibits high strength and high toughness even in a case where the steel member has undergone high-temperature and long-time post-welding heat treatment. The steel member has a prescribed composition and is characterized in that the texture of a thicknesswise central zone of the plate satisfies all the requirements (a) to (d): (a) the texture is tempered bainite and/or tempered martensite; (b) the mean equivalent circle diameter of grains that are each surrounded by a large-angle grain boundary where the misorientation between two adjacent grains is 15 or more is 20 µm or less; (c) the maximum diameter of grain-boundary carbides is 0.8 µm or less; and (d) the fraction of grain-boundary carbides is 1.0% by area or more.

摘要： The field of this invention is nuclear power industry, and its implementation will result in the increased safety of nuclear reactor (NR) operation. The invention may be successfully introduced to liquid-metal-cooled (LMC) reactors, in particular, to fast-neutron nuclear reactors with heavy liquid metal coolant (HLMC), for example, eutectic alloy, lead and bismuth, lead.
The method implies estimation of the damaging dose of fast neutrons (dpa) which results in unacceptable degradation of paste-forming properties of steel. Then, upon achievement of the reactor energy yield, the direction of the coolant flow shall be changed from the standard direction to the reverse direction. Then an acceptable period of time is set for the annealing of reactor core elements, the temperature of the annealing mode is set and maintained by controlling the power level, it shall be sufficient to restore paste-forming properties of steel of the lower core section within the set period of time. At the end of the pre-set annealing period, the direction of the coolant flow shall be changed from reverse to the standard one. A nuclear reactor is also claimed which makes it possible to implement the proposed method.

摘要： A method for heat treating a steel component. The steel component is disposed in a heat treating furnace. The steel component is then exposed to a nitriding atmosphere at a predetermined nitriding temperature for a predetermined nitriding time interval. The nitriding atmosphere has a predetermined composition. The composition of the nitriding atmosphere is controlled while the steel component is exposed thereto. The steel component is slowly cooled to ambient temperature and then removed from the heat treating furnace. The heat treated steel component has substantially increased corrosion and wear resistance compared to the steel component prior the heat treating.

摘要： A heat-resistant metal member suffering from creep damage is covered by a heat-resistant covering member and secured so as to contact an outer periphery of the heat-resistant metal member, and the heat-resistant metal member covered by the heat-resistant covering member is heated to a temperature of 1000°C or greater. A compressive force accordingly acts on the heat-resistant metal member undergoing thermal expansion toward the outer periphery, enabling efficient regenerative heat treatment to be performed on the heat-resistant metal member suffering from creep damage, while restraining thermal expansion in the direction toward the outer periphery of the heat-resistant metal member.
