Microstructure and Mechanical Properties of Fe-Cu-Ni Sinters Prepared by Ball Milling and Hot Pressing

Abstract: The main purpose of this work was to determine the effect of the powder composition on the microstructure and properties of iron-based sinters used as a matrix in diamond tools. The Fe-Cu-Ni sinters obtained from a mixture of ground powders were used for experiments. The influence of manufacturing process parameters on the microstructure and mechanical properties of sinters was investigated. Sintering was performed using hot-pressing technique in a graphite mould. The investigations of obtained sinters include… Show more

“…The cutting segments of diamond tools consists of synthetic diamonds embedded in a metallic matrix. The segments are manufactured by powder metallurgy technology Several metals can be used as matrices in metallic-diamond composites: cobalt, copper, iron, tin, and nickel [1,2]. However, cobalt is the base metal for the production of metallic-diamond segments.…”

“…on the basis of previous research [9], the iron-based material for matrix of metallic-diamond tools was designed. The material was obtained from elemental powders subjected to milling for 30 h. The material was selected for the tests, with the mass fractions of individual powders as follows: 60% Fe, 23.8% cu, 4.2% sn and 12% Ni.…”

“…ESD technology can be an alternative to other techniques for the production of engineering materials, e.g. sinters [3][4][5] We can produce carbide-based coatings using various technologies. Among the beam techniques, we observe a dynamic development of laser processing [6] and a well-established position among surface treatments using the ESD method [7].…”
