Opis:
In Lithuania and, specifically, in its eastern part which falls into the habitat of the East Lithuanian Barrow Culture (c. 3/4th–11/12th century AD), rescue archaeology encouraged the search for new archaeological facts, namely, burials between barrows. The first results considerably shattered the established belief that burials had been made in barrows only and provided an argument in favour of the possibility of a dual burial tradition of both barrows and flat burials. This article focuses on these “atypical graves” detected during the rescue excavations at one of the most representative barrow cemeteries, namely, Jakšiškis barrow cemetery. A detailed analysis of the Jakšiškis barrow cemetery research materials implies, however, that adopting the hypothesis of the flat burials as proven might be premature, and the circumstances of their discovery enable more than one alternative interpretation.

Opis:
This paper presents the assessment of the rapid prototyping finishing techniques for printed components. The aim of the study was to compare the element printed with FDM technology before and after the treatment, using 3D scanning techniques. The object was scanned right after manufacturing, then it was subjected to finishing treatment and 3D-scanned again. The assessment of the results was performed using the GOM Inspect software, based on a comparison between scans and nominal model.

Opis:
This study investigated the effect of heat treatment on the microstructure and impact toughness property of AISI D2 manufactured with direct energy deposition (DED) and compared the results with conventional wrought material. The fracture crack propagation behavior was examined in connection with microstructures through fracture surface analysis. AISI D2 manufactured with DED had a eutectic structure that turned into a net-type carbide after heat treatment, and Cr-rich needle-type secondary carbide was observed. Impact toughness of DED AISI D2 measured 2.0 J/cm2 in the as-built sample and 1.1 J/cm2 in the heat-treated sample. Compared to a wrought heat-treated AISI D2, DED AISI D2 had relatively low impact toughness. DED AISI D2 and wrought material had different crack propagation mechanisms. In DED AISI D2, the eutectic structure and net-type carbide boundary were identified as the major microstructural factor decreasing impact toughness.
