Properties of nickel material (N6)
Pure nickel is a silvery white metal, which is widely used in chemical industry, machinery and electronics, food and other fields because of its excellent corrosion resistance, high electro vacuum performance and electromagnetic control performance. Pure nickel has excellent weldability and processability. Nickel and nickel alloy can be processed into tube, rod, wire, plate, strip and foil products.
Effect of titanium alloy hot process on Microstructure and properties of thick plate
In this paper, the effects of two hot working processes on the microstructure and mechanical properties of bti-6431s high temperature titanium alloy thick plate were studied. The test results show that the structure type of ( + β) rolled thick plate is similar to the equiaxed two-phase zone processing structure, and the microstructure of βrolled thick alloy plate is a typical fine lamellar widmanstatten structure. The room temperature and high temperature strength of this structure thick plate is significantly higher than that of + βrolled thick plate, and the plasticity is slightly lower. The comprehensive analysis shows that the alloy thick plate has high instantaneous strength at 650 ℃ and can be used in the fabrication of 650 ℃ short-term structural parts in aerospace industry. The nominal composition of bti-6431s titanium alloy is ti-6.5al-3sn-3zr-3nb-3mo-1w-0.2si.
