AlSi11 matrix composites reinforced with SiC particles have been fabricated by high pressure die casting assisted ultrasonic mixing. Severe plastic deformation process was performed on the as cast AlSi/2wt.%SiC composite using modified channel twisted output (TCAP) at three temperatures of 350, 400 and 450 °C. The TCAP tool consists helical part in horizontal area allowing for simulation back thus resulted increase extrusion force local deformation. most important issue presented...
In this paper is presented an analysis of a comparison particular non-destructive techniques: radiographic, ultrasonic, eddy current and pulsed infrared thermography to detect flaws in pressure die casting. Furthermore, new way the image segmentation method for porosity detection aluminium casting using results from X-ray public domain software proposed. The research allowed verifying possibility aforesaid methods controlled technological parameters process, thus permitted confirming quality...
This paper presents the results of laser welding dissimilar joints, where low-carbon and stainless steels were welded inthe lap joint configuration. Performed austenitic ferritic-pearlitic included a sealed joint, only partial penetration lower material was obtained.The authors presented acomparative study joints under different configurations. The parameters for assumed estimated via anumericalsimulation. Moreover, stress–strain analysis performed based on theestablished model. Numerical...
Magnesium alloys, due to their unique properties, low density and high strength are becoming more frequently used in industrial applications. However, a limitation of use may be the need ensure abrasive wear resistance corrosion resistance. Therefore, magnesium alloys often protected by applying protective coatings. The paper presents influence modification electrolyte composition, with or without addition borax, on morphology (observed SEM method) phase composition (analyzed EDS XRD) formed...
The study focuses on the aspect of using structure gasars, i.e. materials with directed open porosity, as a potential hydrogen storage. tested gasar is composed large number thin, tubular pores running through entire longitudinal section sample. This allows to easily penetrate into sample volume. analysis pore distribution showed that longest diffusion path needed for full penetration metal about L = 50–70 μm, regardless external dimensions Attempts hydrogenate magnesium have shown its...
Designers’ efforts to use the lightest possible materials with very good mechanical properties mean that in recent years magnesium alloys have been increasingly used. It is well-known of various plastic working processes allows achieving even better strength material, often without significant loss relation products obtained casting process. The article presents results research on microstructural changes and alloy AZ91 (MgAl9Zn1) occurring samples subjected conventional deformation KOBO...
This study reports the results of archaeometallurgical investigations performed on a complete two-part bronze casting mould discovered in village Elgiszewo (north Poland). The was part so-called Lusatian founder’s hoard deposited southern borders Chełmno group territory between 900 and 700 BC. involved employment spectral (ED XRF, SEM-EDS, X-ray)and microscopic (SEM-EDS, OM) analyses. experimental model socketed axe carried out this as well. chemical composition indicates use fire-refined...
Composites are one of the fastest developing materials. Research is particularly intensive in case light metal alloys due to i.a. economic and environmental aspects. One innovative solutions production matrix composites (MMC) by adding cordierite ceramics obtained from fly ashes magnesium alloys. In addition obtaining new-generation materials with improved mechanical properties, also waste utilized which has a significant importance. order select suitable operating conditions for such...
The casting workshop was discovered with numerous artifacts, confirming the existence of manufacturing process metal ornaments using ceramic molds and investment technology in Lower Silesia (Poland) 7-6 BC.The research has yielded significant technological information about bronze field, especially alloys that were used artifacts made from them.Based on analyses, model experimentally reconstructed.Taking advantage computer-modeling method, a geometric visualization bracelets performed;...
This paper presents novel opportunities for management of fly ash by synthesizing the material into cordierite ceramics and using it as a reinforcing phase light metal alloys. Metal matrix composites (based on magnesium alloy aluminum alloy) were produced squeeze casting. The with suitably selected content (2 wt.%) exhibited much better strength properties than unmodified (AM60). It was also demonstrated that wettability (or lack thereof) in metal-ceramic system is critical to successful...
The aim of this study was to determine the effect support phase composition (Al2O3–TiO2) and addition gold on catalytic properties in low-temperature CO oxidation. In paper, physicochemical results measurements performed for obtained samples were investigated. catalyst carriers prepared using sol-gel method with alkoxide Al(C3H7O)3 Ti(C3H7O)4 employed obtain corresponding oxides, case which molar ratio (Al2O3:TiO2) 0.75:0.25, 0.50:0.50 0.25:0.75, thus Al:Ti elements, i.e. 1.5:0.25, 2:1...
Plasma oxidation, similarly to anodic oxidation (anodizing), are classified as electrochemical surface treatment of metals such Al, Mg, Ti and their alloys.This type is used make castings, plastically processed products, shaped with incremental methods suitable for certain requirements.The most important role the micro plasma coating protect metal against corrosion.It well known that aluminium alloys containing silicon using causes significant difficulties.They linked eutectic nature this...
In 2009, an exceptional discovery was made in west-central Poland. At the Late Bronze Age necropolis Wartosław, tools used metalworking were unearthed from a mass grave belonging to Lusatian people that can be dated 1100–900 BCE. Twelve out of over 70 ceramic vessels burial pit identified as urns contained ashes at least eight deceased individuals, including two adult men, one young woman, unspecified adult, and four children. Metallographic, chemical, petrographic investigations mortuary...
