Conclusion
Continuously cast billets of BrOTsS5-5-5 bronze have quite high internal stresses occurring as the result of formation of the casting, which are added to the deformation stresses, and lead first to the formation of a twinned structure (with ε=∼30%) and then to failure of the material (with ε=40%). In comparison with permanent mold ones the structure of such billets is coarse grained with strictly oriented axes of the dendrites in the direction of the solidification front.
