INFLUENCE OF ISOTHERMAL HOLDING ON THE STRUCTURE FORMATION OF TIN BRONZE MODIFIED WITH NICKEL ALUMINIDE
Tin bronzes are a good anti-friction material. The scope of their application is limited due to low strength properties. Strength properties can be improved by changing their structure using heat treatment. This article presents data on the effect of isothermal holding on the structure of cast bronze. It is shown that even small additions of a modifier (0.05 %) based on nickel aluminides make it possible to refine the casting grain, reduce the average size of the electronic compound, and form a dispersed network of eutectoid inclusions.
