Sažetak
During the projected lifespan, most components of the boiler are exposed to increased values of temperature and pressure, flue gasses and variable loads, which are causing significant changes in the structure of the material. Since we live in a time when survival is almost impossible without electricity, halting of the entire power plant in order of taking samples for examination represents enormous expense. Application of metallographic replicas as a method of non-destructive examination of the structure represents a practical and reliable way of detections changes in the layer under the the surface, as well as changes in structure caused by work on elevated temperatures. This method can be used for examination of entire constructions, as well as finished products from the industry. In the experimental part of the work, quality estimation of material used for manufacturing of boiler the headers made of low - alloyed steel 13CrMo4-5 was performed. The aim of the test is a determination of workability of tested components, as well as evaluation of the possibilities for further course of exploitation.
