... was changed into more stable gamma alumina by adding heat treatment in a hydrogen atmosphere at 500 ° C for 1 h, and the source of organic silicon, organosilicon sealant, was removed. The improved catalysts were applied at Hamaoka Units 4 and 5. Moreover, the linseed oil that used to be used at the plants...

... mentioned elements on the nickel-manganese-based systems will be visualized by thermodynamic simulations. Afterward, different compositions in combination with a heat treatment, which is typical for nickel-base superalloys, will be discussed: A microstructure, which is very similar to that within the base...

...–1273 K, 10 h) after the heat-treatment were used. The experimental results suggested that the volume fraction of precipitated aluminum compounds in the VPS MCrAlY coatings and the residual stress induced by the overaluminizing treatment had important effects on the mechanical properties. The Vickers...

... generation picture, which includes stand-alone generation, combined cycle applications with fuel cells, and combined heat and power (CHP) application ( 2 ). creep fracture fracture toughness corrosion resistance austenitic stainless steel crystal microstructure heat treatment costing gas...

... are reduced by the heat treatment at high temperature. There is a tendency that the relative density increases above 95 percent with increasing the heating temperature. It is thought that these densification behaviors of VPS MCrAlYs should arise during...

... in this area. The ability to recover the creep properties of used gas turbine components might enable their service lives to be increased considerably. Thereby, maintenance costs could be reduced. Previous research into the feasibility of reconditioning crept superalloys by heat treatment will be reviewed...

... with a vacuum plasma sprayed MCrAlY coatings. It was confirmed that the mechanical properties of HVOF sprayed MCrAlY coatings could be improved by a diffusion heat treatment to equate the vacuum plasma sprayed MCrAlY coatings. Also, the residual stress characteristics were analyzed using a deflection...
