    Notes: Recently one of the most significant research-field in the development of amorphousalloys is the research of the Cu-based amorphous alloys. The Zr-based alloys developed earlier canbe replaced by the newly developed Cu-based alloys as the high price of the Zr-based alloys limitstheir utilization in spite of their favourable properties. Production of Cu-based alloys having thesame or more favourite properties than Zr-based alloys is cheaper and this fact can promote theirincreasing utilization. Cu-Zr-Ti and Cu-Hf-Ti alloy systems – they are Cu-based alloys – haveexcellent mechanical properties. In this paper investigations of crystallization of amorphousCu44,25Zr36Ag14,75Ti5 powder produced by ball milling (these processes have not been investigatedyet according to the reference data) are described. In the course of investigation of thecrystallization process, samples were heated to a temperature of investigation by means of a DSCequipment and the developed state was frozen by chilling. The investigation of the developedstructure and to identify the phases formed during heat treatment, X-ray diffraction method wasused

    Lymphocytotoxic antibodies in lightdermatoses (1977)

    Description / Table of Contents: Zusammenfassung Das Vorkommen von lymphocytotoxischen Antikörpern vom “kalten Typ” wurde bei 92 Patienten mit verschiedenen Photodermatosen untersucht. Während solche Antikörper im Sera der Patienten mit cutaner Porphyrie in 39% der Fälle nachgewiesen werden konnten, wurden diese bei Patienten mit polymorpher Lichtdermatose in keinem Falle gefunden. Es konnte gezeigt werden, daß das Auftreten lymphocytotoxischer Antikörper, die Dauer des Bestehens der Porphyrie und der Schweregrad der Leberschädigung miteinander korrelierten. Die Befunde weisen auf eine langfristige Gewebeschädigung bei der Entstehung dieser Antikörper hin. Die Ergebnisse stehen im Einklang mit der Auffassung, daß die polymorphe Lichtdermatose nicht zur Gruppe des Lupus erythematodes gehört.
    Notes: Summary Occurrence of lymphocytotoxic antibodies of the “cold-type” was studied in 92 cases with various lightdermatoses. They were detected in the sera of 39% of the patients with cutaneous porphyrias and never in cases with polymorphous light eruption and other photodermatosis. Correlations between their presence and the duration of the porphyria as well as the severity of hepatopathy could be observed. The results indicate the importance of a long-standing tissue damage in the production of these antibodies. In addition the findings confirm the hypothesis according to which polymorphous light eruption does not belong to the lupus erythematosus entity.

    Notes: Copper alloys have many properties, which make them suitable in wide-rangingapplications in all the engineering industries. For the investigated alloys the most importantproperties are hardness, strength and electrical conductivity. Precipitation hardenable alloys werestudied by Jominy end-quench test, in order to examine the change of hardness, electricalconductivity and microstructure as a length of the test bar (i.e. cooling rate). In the first step sampleswere solution treated at different temperatures, then water quenched followed by aging. Cold-workafter quench was applied in some alloys and improve in the properties was clearly seen. Thefollowing Cu-alloys were investigated: Cu-Co-Ni-Be, Cu-2Be-Ni and Cu-2Ni-Be

    Investigation of Ageing Phenomena in CuAlNi Based Shape Memory Alloys (2007)

    Notes: The ageing phenomena and its effect on the thermoelastic martensitictransformation was investigated in three Cu-base SMAs. The transformation temperaturesshifted to higher temperatures due to aging in the beta-phase.To increase the alloy’s ductility, a definite amount of Mn (4 wt%) and Fe (2 wt%) were addedto the ternary alloy. The thermoelastic martensitic transformation was found in the not-agedsamples of the CuAlNiMn and CuAlNiMnFe alloys. This transformation was destroyed dueto ageing heat treatments by a fairly unknown exothermic process. The thermoelasticmartensitic transformation appeared again in the aged CuAlNiMn and CuAlNiMnFe samplesafter keeping them on room temperature for a few months.This phenomena was investigated by DSC, SEM, TEM, and XRD

    Notes: During thermomechanical treatment of austenitic stainless steel a’ martensite and emartensite form in the austenite matrix. The martensitic transformation and deforming existing together result a high elongation at the investigated steel belonging to the TRIP grades. The amount of a’and e martensite depends on the strain level as well as on the deforming temperature in this steel. In the course of thermomechanical treatments we measured the amount and texture of the existing phases at different temperature and strain. It has been stated that the martensites are dominant in low temperature range, they have a considerable amount, and the transformation from emartensite to a’ martensite also takes place. The amount of a’ martensite increases by increasing the strain while the amount of e martensite shows a maximum. By investigating the relationship between the quantity of existing phases and the effect of texture, it has been stated that the transformation takes place in certain given plates in the textured matrix
