The invention relates to a tungsten-copper composite material forming part and a preparation method thereof, and belongs to the technical field of metal composite materials. The raw materials of the forming part are composed of a tungsten source, a copper source and a forming agent. The tungsten source consists of modified tungsten powder and tungsten powder; the modified tungsten powder is obtained by adding a reinforcing phase and an activating element, wetting and adhesion of a tungsten phase and a copper phase can be promoted, the sintering performance of the formed part is improved, and the comprehensive performance of the formed part is improved; the forming agent is added to ensure that the powder has good flowability and formability, the problems that a large-size tungsten-copper blank is poor in compression molding formability and high in manufacturing cost are solved, and a tungsten-copper composite material formed part which is uniform in structural component, low in cost and easy to form is obtained. The preparation method comprises the following steps: dispersing an activating element and a reinforcing phase into tungsten powder through a ball milling method to obtain modified tungsten powder, adding double-granularity composite powder of the modified tungsten powder and unmodified tungsten powder into a forming agent to obtain easily-formed composite powder, and pressing the composite powder into a large-size tungsten copper green body, the method has the characteristics of low cost, good repeatability, controllable process, raw material saving and the like.

The invention relates to the technical field of piezoresistor preparation, in particular to an ultrahigh-voltage pulse strontium titanate annular piezoresistor and a preparation method thereof. Comprising the following components in parts by weight: 20 to 25 parts of strontium carbonate, 20 to 25 parts of barium carbonate, 11 to 15 parts of calcium carbonate, 33 to 36 parts of titanium dioxide, 0.17 to 0.20 part of niobium oxide, 0.1 to 0.3 part of silicon dioxide, 0.01 to 0.20 part of aluminum oxide, 0.01 to 0.50 part of manganese carbonate, 5 to 10 parts of tin dioxide, 0.01 to 0.20 part of zinc oxide and 0.2 to 0.7 part of a nano material. The aluminum oxide, the manganese carbonate, the tin dioxide and the zinc oxide are added on the basis of a traditional formula, the purposes of improving the pulse resistance, improving the nonlinear coefficient and the capacitance value and reducing the loss are achieved, meanwhile, the introduced multi-layer nanofiber material and the three-dimensional composite nanomaterial are matched with each other, and therefore the pulse resistance is improved. The integral strength of the material can be effectively enhanced, so that the formed annular piezoresistor is compact in structure, high in strength, strong in external force resistance and good in breaking strength, thereby achieving the effect of enhancing the strength of a porcelain body.
