Abstract:

The strengthening effect of GaAs by indium additions is under examination. Solid solution strengthening by InAs4 solute units has been predicted and is studied via mechanical measurements complemented by electron microscopy. In this second quarterly report, hardness measurements for three Ga1-xInxAs compositions from R. T. to 900 C are complete and the second stage of the experimental work, compression testing, as a function of temperature and strain rate, is underway.
