A method of manufacturing a composite member including an aluminum member and a resin member that are bonded to each other, the method including: performing blasting on a surface of the aluminum member; modifying the surface of the aluminum member into aluminum hydroxide, the modifying including causing the surface of the aluminum member having undergone blasting to react with water vapor by applying a pressure exceeding an atmospheric pressure; and directly bonding the resin member to the surface of the aluminum member modified to aluminum hydroxide.

An austenitic stainless steel includes a mixed grain structure composed of a columnar crystal having an average crystal grain size of 20 &#x3bc;m or less and an equiaxed crystal having an average crystal grain size of 5.0 &#x3bc;m or less, in which an area proportion of the columnar crystal in the mixed grain structure is 20% or more, and an average crystal grain size of the whole mixed grain structure is 5.0 &#x3bc;m or less. Accordingly, it is possible to provide a material having excellent irradiation resistance and mechanical properties.

Austenitic stainless steel and reactor internal structure

An objective of the invention is to provide an austenitic stainless steel article having superior irradiation resistance and stress corrosion cracking resistance than before while maintaining mechanical properties equivalent to those of conventional ones. There is provided a dispersion strengthened austenitic stainless steel article, including: 16-26 mass % of Cr; 8-22 mass % of Ni; 0.005-0.08 mass % of C; 0.002-0.1 mass % of N; 0.02-0.4 mass % of O; at least one of 0.2-2.8 mass % of Zr, 0.4-5 mass % of Ta, and 0.2-2.6 mass % of Ti; and a balance consisting of Fe and inevitable impurities. The Zr, Ta and Ti components form inclusion particles in the stainless steel article by combining with the C, N and O components. The stainless steel article has an average grain size of 1 &#x3bc;m or less and a maximum grain size of 5 &#x3bc;m or less.

The present invention is characterized in that in a simulation for predicting a steam pressure setpoint after grade change, an initial moisture percentage is evaluated from differences between bone-dry basis weights and between machine speeds before and after grade change; the bone-dry coated weight of a size is evaluated from the flow rate and concentration thereof; and then the dryer inlet moisture percentage of a web after a size press is calculated from the coated weight. Thus, the invention intends to improve the quality of products through precise dryer control, as well as reduce the time required for grade change, by precisely predicting the web's initial moisture percentage at the dryer inlet after grade change and precisely and quickly controlling dryer steam pressure during grade change.
