Abstract

The effect of Sr additions on the microstructure and strength of a Mg5Al3Ca alloy was investigated by replacing Ca with Sr In the ascast alloys the major intermetallic compound observed at the αMg dendrite cell boundary region changes from the Alrich Mg Al2Ca phase to the Mgrich Mg17Sr2 phase with increasing Sr content This results in an increased Al solute content in the αMg phase in the highSr containing alloys More than 1 wt pct of Sr enhances the solidsolution strength of the αMg phase resulting in the increased compression strength of the alloysThis research was supported by NSF FRG Grant No DMR0309468 and the Assistant Secretary for Energy Efficiency and Renewable Energy Office of Freedom Car and Vehicle Technologies as part of the High Temperature Materials Laboratory User Program Oak Ridge National Laboratory managed by UT–Battelle LLC for the United States Department of Energy under Contact No DEAC05000R22725 The authors are thankful to CJ Torbet C Henderson University of Michigan Dr BR Powell N Irish General Motors and Dr P Bakke Norsk Hydro for their assistance
