Tantalum is mainly found in tantalite, tantalum texture is very hard, full of malleability, the biggest advantage of tantalum metal is that it has very high corrosion resistance, no matter in cold or hot conditions, no reaction to hydrochloric acid, concentrated nitric acid and aqua regia. Tantalum can quickly form a surface oxide film in almost any environment, which is extremely thin and dense, impervious to almost all media, and can immediately heal itself once damaged. Tantalum alloy is a tantalum based alloy with other elements. Tantalum alloy has the characteristics of high temperature resistance, high strength, good chemical stability and corrosion resistance, and is an indispensable material in the fields of aerospace industry, atomic energy industry, high temperature technology and chemical corrosion prevention. Therefore, the preparation of tantalum alloy has become a research hotspot.
The existing alloy structure distribution is not uniform, the strength and toughness properties are poor, the tensile strength, toughness and elongation can not achieve coordinated improvement, and the existing heat treatment extrusion deformation process is simple, it is difficult to improve the performance of the product, based on this, the invention provides a tantalum material deformation preparation method.
Without the addition of homogeneous denaturing agent, the strength and elongation of the product are significantly reduced. At the same time, the addition of modified graphene can improve the strength and elongation effect of the product, and the product is not treated with deformation co-conditioning solution. The deformation co-conditioning solution of the product is prepared differently, and the performance of the product is all deteriorated. The preparation method of the invention can be used to coordinate the improvement of the strength, elongation and other properties of the product.
