Microstructure and properties of beta 21s alloy with 0.2 wt.% of carbon

Taking into account the high requirements of new structural materials the development of high-strength and high-temperature alloys based on titanium is a subject of great scientific interest. Carbon has usually been regarded as an impurity of titanium alloys. Increasingly however, it begins to play an important role as alloy addition and, taking into account its price, it is consistent with the global cost-cutting trend for production and processing of new alloys with improved properties. The addition of carbon creates new application opportunities for titanium alloys. The relationship between mechanical properties and microstructure of Beta 21S alloy with carbon addition were considered in this study. The alloy was produced traditionally by vacuum induction melting in cold crucible furnace and hot-deformed with further heat treatment. The effect of heat treatment on the conventional strength and creep resistance of researched alloy was also determined.
