Embodiment 1

[0067] According to the mass percentage, weigh 4.53% Al, 2.20% Mo, 0.59% Zr, 0.15% Si, 0.15% Fe, 0.021% C, and the balance is sponge titanium, the sum of the mass percentages of each component is 100%. After mixing Al, Mo, Zr, Si, Fe and C on the aluminum foil, wrap it into a strip-shaped alloy bag; press the electrode with a vertical horizontal pressing machine, and weigh the electrode in the previous step according to the number of electrodes to be pressed. The titanium sponge is divided into several equal parts, and each part of the titanium sponge is divided into two parts on average. First, one part is added to the mold and distributed evenly along the length of the mold. Then, the alloy package is placed into the titanium sponge along the axial direction of the mold. A piece of titanium sponge is evenly spread on the upper end of the alloy bag, and the press is started to press the electrode. The size of the press is 1000 tons, and the alloy bag is wrapped with sponge ti...

Abstract

The invention discloses a standard substance for TC11 titanium alloy photoelectric spectral analysis, which comprises the following components in percentage by weight: 4.53% to 7.51% of Al, 2.2% to 4.65% of Mo, 0.59% to 2.41% of Zr, 0.15% to 0.46% of Si, 0.15% to 0.35% of Fe, 0.021% to 0.12% of C and the balance of titanium, wherein the weight percentage sum of the components is 100%. The preparation method of the standard substance comprises the following steps: dosing; suppressing electrodes by utilizing a vertical lateral pressure machine; welding the electrodes in a vacuum argon charging tank; smelting primary cast ingots by utilizing a vacuum consumable electrode arc furnace; casting secondary cast ingots by utilizing a vacuum consumable electrode arc skull furnace; smelting tertiarycast ingots by utilizing the vacuum consumable electrode arc furnace; homogenizing and carrying out transform processing; and carrying out hot hydrogen processing to prepare the standard substance for the titanium alloy photoelectric spectral analysis. The standard substance and the preparation method of the invention have the advantages that the homogenization of the components is good; the problem that alloy elements cannot be effectively detected because the Zr element has no effective distribution point in the content section of 0.6 to 2.6% and the Mo element has no effective distributionpoint in the content section of 2.2 to 4.6% in the existing standard substance is solved.

Description

technical field [0001] The invention belongs to the technical field of analysis and detection, and relates to a standard substance for measuring and detecting titanium alloy materials, in particular to a TC11 titanium alloy photoelectric spectrum analysis standard substance, and also relates to a preparation method of the standard substance. Background technique [0002] TC11 is a new type of aviation and aerospace material, which belongs to α+β two-phase structure titanium alloy, and has good comprehensive mechanical properties, high temperature strength, thermal stability and creep properties. TC11 titanium alloy is currently one of the most mature heat-strength titanium alloy grades with the largest amount of use in aero-engines in my country, the highest temperature (500-520°C), and the most mature application. [0003] Aluminum, molybdenum, zirconium, silicon, iron, and carbon are important components of TC11 titanium alloy materials, and their influence on material pro...
