1	The Evaporation of an Iron - 5 Percent and an Iron - 25 Percent Chromium Alloy in the Temperature Range 900°C to 1080°C / The Evaporation of an Iron - 5 and 25 Percent Chromium Alloy Morris, Larry 10 1900 (has links) In this thesis, the theory of metal crystal evaporation and of vapour pressure determinations are presented, followed by a literature survey on the evaporation characteristics of iron, chromium and alloys of iron - chromium. Results are presented for an investigation carried out on the free evaporation kinetics of iron base alloys containing 5 percent and 25 percent chromium for the temperature range 900°C to 1080°C. Also, a complete description of the surface topographies of evaporated specimens is presented using normal, hot stage and interferometric microscopic techniques. These results are correlated in terms of the evaporation theory and pertinent experimental data reported for other metallic systems. / Thesis / Master of Science (MSc) evaporation iron 5 percent chromium alloy iron 25 percent chromium alloy iron - 5 percent chromium alloy iron - 25 percent chromium alloy chromium alloy metallurgy 900°C to 1080°C temperature range 900°C to 1080°C temperature range of 900°C to 1080°C
