This paper is dedicated to an experimental program focused on the evaluation of microstructure and failure mechanisms WWER 440 type nuclear reactor pressure vessel cladding made from Sv 08Kh19N10G2B stainless steel. Static fracture toughness tests performed standard precracked single edge bend specimens revealed extreme variations in values, J0.2. Fractured halves test were subject detailed fra...

Abstract The microstructure of Fe-15Mn-10Al-5Ni-0.8C low density duplex steel ingots was studied by laser confocal scanning calorimetry , metallographic microscopy and electron microscopy. results indicated that: the mainly composed coarse austenite dendrites δ -ferrite phase in dendrite. could be completely eliminated solution treatment. A dynamic model grain growth established. Through analys...

Planning a process of production, among other machining processes, is an important stage in the production products. The developed should allow parts with planned dimensional accuracy and specified surface roughness. With reference to above, scope carried out theoretical work included determining dependences between parameters drilling process, tool wear, as well impact these on hole quality. m...

The microstructure is an essential part of materials, storing the genes materials and having a decisive influence on materials' physical chemical properties. material genetic engineering program aims to establish relationship between composition/process, organization, performance realize reverse design thereby accelerating research development new materials. However, tissue analysis methods sci...

Non-destructive Eddy current (EC) technique has long been used to detect discontinuities in materials. Recently, its application has been extended to characterize materials microstructure. In order to identify different microstructures, four plain carbon steel bars with different chemical compositions (AISI 1015, 1035, 1045 and 1080) were used in annealed condition. The pearlite percentage, car...

The high cooling rates reached during metal additive manufacturing (MAM) generate microstructures very different from those obtained by other conventional methods. Therefore, research about the modeling of this type microstructure is great interest to MAM community. In work, prediction lamellar spacing an AlSi10Mg sample manufactured laser powder bed fusion (LPBF), presented. A multiscale appro...

Metallographic analyses of nodular iron casting methods are based on visual comparisons according to measuring standards. Specifically, the microstructure is analyzed in a subjective manner by comparing extracted image from microscope pre-defined templates. The achieved classifications can be confused, due fact that features human being could interpreted differently depending many variables, su...
