Tantalum plates cannot be processed by ordinary methods of processing ordinary metals. Generally, the initial process is forging, processing and heat treatment, and two methods of hammering and stamping are used to make flat blanks or round small and medium-sized blanks. Unlike ordinary metals, tantalum cannot be hot worked. The recrystallization temperature of tantalum exceeds 1000~C. If heated, excessive oxidation will occur even if a general protective layer is applied. What's more serious is that if tantalum is exposed to such a high temperature, not only will excessive oxidation occur on the surface of tantalum, but oxygen can also penetrate into the inner space of the matrix, making tantalum brittle. Not only oxygen, but even nitrogen, carbon and hydrogen can make tantalum brittle. Tantalum is generally not hot worked. When thermal processing is performed, a protective coating or an inert gas atmosphere is required.
