Abstract

α/gg-titanium-aluminide is a very suitable material for engine valves in the automobile industry. This lightweight, high temperature material has many advantages over 21-2N stainless steel. Of course the cost of TiAI-valves must be competitive. The existing production route for titanium alloys is not applicable for the valve production because of economic reasons.

We have developed a new cost saving process consisting of melting, alloying using a cold crucible furnace and centrifugal casting in a preheated permanent mold in a single step. The present article describes the new process along with the most recent results.

    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].

    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).
