Abstract
The accomplishments of the contract period October 8, 1959 to February 7, 1961 are summarized. The experimental investigations on the effect of high hydrostatic pressure on phase transformations in various substitutional iron-base alloys, including iron-chromium, iron-nickel and iron-silicon, yield data which are in close agreement with theoretical prediction. A study of the effects of pressure on iron-carbon alloys shows a general shift of the equilibrium phase boundaries to lower carbon contents and temperatures with pressure. Pressure also acts to retard both the rate of tempering and the isothermal transformation of metastable austenite. The synthesis of f.c.c. MoC was carried out at pressures in excess of 35 kilobars at a temperature of 2000°C. The thermally activated recovery and recrystallization processes are shown to be retarded in a study of copper and 70-30 brass. Preliminary studies have been carried out on the high pressure sintering of Al2O3.
