The effect of thermal action at 1100 °C on the kinetics of phase transformations in the coating obtained after aluminizing of 12Kh18N10T steel by immersion in a melt is studied. It was shown that after 500 hours of exposure, the chemical composition is leveled over the entire volume of the sample. Moreover, the predicted retention time of the heat-resistant properties of the coating at 1100 ° C is about 2000 hours.

Dissimilar Welding of Austenitic and Martensitic Stainless Steel Joints are commonly preferred in Nuclear Reactors where high temperature applications are needed. There has been a huge demand for materials which sustain corrosive environment with high rupture strength along with high temperature and pressure. These materials can be directly replaced with the traditional nickel based alloys to compensate for cost cutting and satisfy strength requirements. Dissimilar welding of these materials has been challenging due to the difference in its composition, properties and also heterogeneity in microstructure of these materials. A Study was done to identify what are the commonly used joining techniques, the mechanical properties of the joints and also the microstructure evolution of the dissimilar weld joints. This paper will emphasize on the work that was previously published in the area of dissimilar welding of these combinations of materials and also their challenges.

Bonding Technique

The development of technologies for joining ceramics and metals is connected with an introduction of new ceramic materials and new applications of ceramic-metal joints, to work in ever more difficult conditions. It concerns mainly ceramic-metal joints working at high and variable temperatures (a facing layer of burners, turbine vanes, etc.) or in a chemically aggressive environment (chemical apparatuses, purification plants). This paper presents the analysis of the influence of the bonding technique on thermal residual stresses generated in ceramic-metal joints and their properties. Technological bonding tests were made using well-known diffusion bonding and powder metallization techniques, and with elaborated sintered Al2O3-Cr gradient interlayer. Numerical calculations (the finite elements method) of the state of thermal residual stresses, as well as the verifying technological tests, were made for the following pair of materials: Al2O3 ceramics - heat resisting steel. There were also made tests of resistance for sudden temperature changes and for oxidation at high temperature. There was found a significant effect of the bonding techniques on the thermal residual stresses and properties of obtained alumina-steel joints.

Currently there is a great interest in developing nickel base alloys with fine and uniform dispersion of stable oxide particles, for high temperature applications. It is well known that the high temperature strength and stability of an oxide dispersed alloy can be greatly improved by appropriate thermomechanical processing, but the mechanism of this strengthening effect is not well understood. This investigation was undertaken to study the dislocation substructures formed in beryllia dispersed nickel alloys as a function of cold work both with and without intermediate anneals. Two alloys, one Ni-lv/oBeo and other Ni-4.5Mo-30Co-2v/oBeo were investigated. The influence of the substructures produced by Thermo-Mechanical Processing (TMP) on the high temperature creep properties of these alloys was also evaluated.
