Report on research works: 25 pages, 1 table, 8 figures, 25 references.
The object of research: heteric materials with a sufficient level of porosity and high sorption properties.
Research methods: optical and microscopy, study of mechanical characteristics.
The processes of microstructure evolution in single-component heteromaterials were studied. The difference between titanium and zirconium getters in residual porosity is shown. The reasons for the formation of final microstructures for these materials have been determined. It is shown that for titanium getters it is possible to achieve a final porosity of 30%, and for zirconium - 22%.
The influence of the parameters of the powder process of alloy manufacturing (use of different powder fractions, pressing pressures and sintering modes) on the microstructure and porosity was analyzed, a general technological scheme and recommendations for obtaining single-component getter materials with the desired mechanical characteristics and residual porosity were developed.
Key words: getter materials, powder mixtures, watered powders, sintering, microstructure, porosity, mechanical characteristics.
