| description | The subject of the work discussed herein and carried out as a part of the Polish National Centre of Research and Development project titled ”Development and implementation of critical technology demonstrators for the new generation of 120 mm tank artillery ammunition” are the results of a research into the influence of LPS (Liquid Phase Sintering) parameters and heat treatment on the mechanical properties of W91Ni6Co3 and W91Ni6Co2.25Fe0.75 alloys, designated PR200 and PR201, respectively. The alloys, as LPS-processed and heat treated, were tested on a strength testing machine to determine their tensile strength (Rm), proof stress (Rp0.2) and elongation (A5). The analysis of the test results resulted in a proposal of manufacturing process parameters to have the alloys tested develop specified mechanical properties.
It was found the ternary alloy with chemical composition W91Ni6Co3 and designated PR200 was more promising in the feasibility of producing specified mechanical properties. The alloy, once sintered and heat treated in two stages, could facilitate production of a material with a tensile strength Rm>1400 MPa, a yield strength Rp0.2 > 1350 MPa, a minimum elongation of 11%, and an impact strength > 115 J/cm2. |
