Przedstawiono wyniki badań mikrostruktury oraz właściwości mechanicznych odlewów piaskowych z brązu BA1055 stosowanego do wyrobu pędników okrętowych. Stwierdzono, że nawet niewielkie zmiany w składzie chemicznym mogą znacząco wpływać na zmiany mikrostruktury oraz właściwości mechanicznych stopu. Wykazano, iż optymalne właściwości mechaniczne uzyskują odlewy, w których stosunek ilości pierwiastków...
The microstructure and resultant mechanical properties of the MM55 manganese brass applied to ship sand - cast propeller were investigated in relation to the propeller blade section thickness. It was stated that the increase of blade section thickness from 15 mm to 45 mm resulted in the increase of the volume fraction of alpha-phase by 5.3% and that of k-phase by 23.7%, the decrease of the volume...
