New kinetic theory capable of dealing with the simultaneous precipitation of several phases has been applied to a variety of creep resistant power plant steels. It has been demonstrated that the model has the ability to predict the vast differences in precipitation kinetics reported in the published literature for power plant steels. New experimental results on precipitation in a 9Cr 1 Mo type ...

S. Krum, F. Pešlová, Czech Technical University in Prague, Faculty of Mechanical Engineering Prague, Czech Republic, J. Kliber VŠB TU Ostrava, Czech Republic Corrosion resistant steels are used for the prod uction of parts exposed to corrosive environment and also to thermo-mechanical loads. Steel molds in the glass manufacture industry with their functional surfaces simultaneously exposed to t...

We report a computational 'alloy by design' approach which can significantly accelerate the design process and substantially reduce the development costs. This approach allows simultaneously optimization of alloy composition and heat treatment parameters based on the integration of thermodynamic, thermo-kinetics and a genetic algorithm optimization route. Novel steel compositions and associated...

Abstract The effect of cobalt and aluminium on the austenite-to-pearlite transformation in a super-bainitic steel was investigated. The experimental work s...

This paper deals with the temperature-dependent modelling of iron losses in context magnetic ageing electricals steel used high power electrical machines. First, two sheet grades were heat treated at three temperatures order to study effect evolution as a function temperature. Results show significant increase for both grades. Then, considering link between macroscopic properties (effect) and m...

A series of 18 Ni (300 grade) maraging steels of overall commercial purity but containing also deliberate impurity additions of sulphur, phosphorus, carbon, chromium and silicon + manganese has been studied. The fracture toughness and stress-corrosion resistance (determined using planestrain fatigue-precracked specimens tested in 3. 5% sodium chloride solution) of these steels have been compare...
