Influence of technological factors of melting on the structure and properties of modified heat‑resistant chrome bronzes
Published 2023-12-01“…The phase composition and physico‑mechanical properties of experimental bronzes have been studied.It has been established that the use of a mechanically fused modifying ligature with a high content of alloying component having chromium particles close to micro‑/nanodisperse size with a non‑oxidized surface and a highly effective deoxidizer modifier reduces the temperature and duration of melting, obtaining alloys with a microcrystalline type of structure (2–5 microns) and a complex of physico‑mechanical properties not inferior to, and in terms of heat resistance superior analogues, which is confirmed by the data of production tests at JSC “Belcard” (Grodno, RB) of contact spot welding electrodes made of experimental bronzes, which are 3.8 times more resistant than those used by the plant.…”
