We lding and brazing of golden parts frequently are obvious in usage for the purposes of gold jewel making. Therefore, it becomes reasonabl...

Creep damage of pressure equipment invol ves a great variety of high temperature components ranging from superheaters, bo iler drums, furnaces, reactors, etc. Consequences of failures of these components are of high economic and safety concern. Moreover, the probability of failure of high temperature components is now increasing due to frequent cyclic of power plants im posed by a deregulated market and the search for increasing temperatures in ultra supercritical plants. A housing from high-pressure steam turbine...
