EFFECT OF CALCIUM CARBIDE MODIFICATION ON THE MECHANICAL PROPERTIES OF BA 1044 BRONZE

The effect of solution heat treatment with jet cooling and modification with C + Ca and CaC₂ on the behaviour of BA1044 alloy in as-cast state, and after solution heat treatment and toughening was examined. The microjet modification and solution heat treatment are clearly beneficial for the R_p0,2 in quenched and tempered state. High-temperature annealing enables obtaining higher plastic properties, while low-temperature annealing improves the mechanical properties.
