Properties of NiCrW alloys during long-term high-temperature annealing

The results of investigation of mechanical properties and their changes during long-term annealing are presented for model NiCrWC alloys. The relationship between the alloy properties and its microstructure is discussed

Properties and microstructure of cast nickel-chromium alloys containing tungsten and carbon as alloying elements

Model fast nickel-chromium alloys containing W and C as alloying elements exhibit markedly better creep resistance than is possible with currently available commercial nickel-chromium alloys. The model alloys are reinforced by primary and secondary tungsten carbides

Binary Titanium-tantalum alloys and their Biocompatibility

The paper deals with investigation of biological properties of binary alloys of titanium with tantalum in relation to the ratio of mass share of tantalum in the alloy. Tests of cytocompatibility and genotoxicity have been made. The tests of cytocompatibility included those of cell growth, cell adherence, dilation test, tolerance test in monolayer, and in suspension. The genotoxicity tests encompassed those of induction of atypical mitoses, induction of chromosomal aberrations in a cell line and in human peripheral lymphocytes. Based of the evaluation of these biological tests the authors determined suitability of using such alloys in oral implantology. Beta alloys formed in this way can be recommended for use in the production of implants
