| Abstract | Hot tearing continues to limit the industrial use of many aluminium casting alloys. The hot tearing susceptibility of an alloy is influenced by microstructure, solidification rate and the stress/strain conditions it experiences during solidification. In this study, a novel technique was used to quantify the residual strain associated with hot tearing in B206 aluminium alloy. Neutron diffraction strain mapping was carried out on three B206 castings with varying levels of titanium (i.e. unrefined, 0·02 and 0·05 wt-%). Titanium additions were effective in causing grain refinement of the alloy and eliminating hot tears. Neutron diffraction strain mapping was successfully used to demonstrate more uniform distribution of strain in the casting, resulting from grain refinement with consequent higher resistance to hot tearing. |
