Many people know about the metal material of polished tantalum plates. It has a high melting point, good electrical and thermal conductivity, high chemical stability, excellent high-temperature strength, good workability, and can be Solderability, low plastic-brittle transition temperature, excellent dynamic mechanical properties, and the formation of a dense, stable, high-dielectric constant amorphous oxide film on the surface after oxidation treatment, etc., are widely used in electronics, chemical industry, aerospace, military weapons, medical and health and other fields.
Polished tantalum plates are mainly used in the electronics industry. Tantalum capacitors are small in size, large in capacity, high in reliability, long in life, good in pressure resistance, and stable in function. They have been widely used in communications, computer integrated circuits, automotive electronic control systems, digital appliances, etc. Very broad applications.
The shell of the all-tantalum capacitor is a deep-drawn cup protrusion. The pure tantalum plate produced in China is prone to cracking, wrinkling, orange peel, ear-making, and other phenomena when the tantalum shell is deep-drawn, the yield is low and it is difficult to achieve high performance. , High-reliability requirements. At present, the influence of cold deformation and heat treatment process on the mechanical properties of pure tantalum plate has not been studied. The drawing and stamping forming of tantalum capacitors for medical treatment is the application background. By controlling the heat treatment process, the mechanical properties of tantalum and its tensile deformation mechanical properties are studied, which provides a theoretical basis for formulating the drawing process of tantalum.
The morphology analysis of the tensile fracture showed that after pre-deformation and heat treatment, the tantalum plate changed from ductile fracture to brittle fracture, and the fracture mechanism was a mixed fracture, which consisted of intergranular fracture, cleavage fracture, and ductile fracture. The analytical and mechanical properties results are the same.
