Oxidation of Ti-46Al-8Ta in air at 700 °c and 800 °c under thermal cycling conditions
2013, IntermetallicsCitation Excerpt :They have low densities 3.8–4.0 g/cm3, good high-temperature specific strength, excellent creep properties and reasonable oxidation resistance up to 700 °C [10,11]. The following properties are regarded as major disadvantages: low room-temperature ductility and fracture toughness [12], insufficient oxidation resistance at temperatures exceeding 800 °C [13], difficult and high-cost production [14]. Moreover, at elevated temperatures titanium aluminides are prone to embrittlement caused primarily by dissolved oxygen and hydrogen [15,16].
Magnetic field in a near-rectangular cold crucible designed for continuously melting and directionally solidifying TiAl alloys
2012, Journal of Materials Processing TechnologyCitation Excerpt :The electromagnetic cold crucible (EMCC) has recently attracted much attention because of its unique advantages, such as its ability to melt reactive metals and refractory materials, its low contamination and its longevity, among others. TiAl valves prepared using an EMCC were reported by Choudhury and Blum (1996). Production of WC particles (with a melting point of 2880 °C) using an EMCC was reported by Chen (2005).
