The effect of blade thickness on microstructure and mechanical properties of ship's sand-cast propeller

Piaseczny L., Rogowski K.

Polish Maritime Research

2007

nr 4

15-17

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 fraction of betha-phase by 2.9%, the 0.2% proof stress R0.2 by 11.3%, the ultimate tensile strength Rm by 5.5% and the 5.65 So elongation A5 by 16.8%.
