In the preparation process, titanium or titanium alloys and boron carbide powder are sintered in vacuum under the conditions of a temperature of 1150 to 1350 DEG C and the pressure of 50 to 200MPas for 0.5 to 4 hours, and then, the products are extruded and molded at a temperature of 1000 to 1200 DEG C. The composite material of the present invention has high room temperature strength and a favorable high temperature property.
Description
The present invention relates to metallic substance, a kind of high-strength in-situ growth ceramic whisker and the compound enhancing titanium matrix composite of particle are provided especially.
Traditionally, titanium matrix composite adopts macrofiber (such as silicon carbide fiber) as wild phase usually, however under the high temperature preparation condition macrofiber usually with the serious surface reaction of titanium matrix generation, greatly reduce the mechanical property of matrix material.One of measure that improves this situation is that original position forms the discontinuous ceramic enhancement phase compatible with matrix in the titanium matrix, and wherein a titanium boride and titanium carbide are best selections, because they and titanium matrix are complete compatible.One of factor that influences the metal-base composites performance is the shape and size of ceramic enhancement phase, and tiny ceramic particle can obviously improve the intensity of material, and whisker then helps to improve the high temperature creep drag and the toughness of material.Therefore, if original position forms the titanium matrix composite that a titanium boride whisker and tiny titanium carbide particle are expected to obtain having high room temperature strength and good properties at high temperature in the titanium matrix.Although prepare a titanium boride and titanium carbide (or carbonization two titaniums) enhancing titanium matrix composite existing document (Mater.Sci.Eng., vol.A149, No.2 (1992), 253-257 by titanium-norbide system; Scripta Mater., vol.41, No.1 (1999), 39-44 and Mater.Sci.Technol., vol.12, No.3 (1996), 219-226) report, but what adopt all is castmethods, owing to be subjected to the restriction of curing condition, one titanium boride is difficult to grow up to the whisker of big L/D ratio, and titanium carbide such as can not form usually at axle shape particle.
The object of the present invention is to provide compound enhancing titanium matrix composite of a kind of high-strength in-situ whisker and particle and technology of preparing thereof, this matrix material has high room temperature strength and good high-temperature performance, can be used for the occasion of various requirement high strength, high use temperature.
The invention provides the compound enhancing titanium matrix composite of a kind of high-strength in-situ whisker and particle, it is characterized in that: this matrix material is made up of the titanium boride whisker, titanium carbide granule and the titanium matrix that align along the direction of extrusion, diameter of whiskers is 0.2-15 μ m, length is 5-500 μ m, titanium carbide granule is of a size of 0.1-10 μ m, the volume content of original position wild phase is at 5-40%, and wherein the mol ratio of a titanium boride and titanium carbide is 4: (1 ± 0.05).
The present invention also provides the preparation method of above-mentioned high-strength in-situ whisker and the compound enhancing titanium matrix composite of particle, it is characterized in that preparation process is as follows:
Adopt physical mechanical method to make the titanium of 40-150 μ m or the boron carbide powder uniform mixing of titanium alloy and 0.5-15 μ m, the weight ratio of titanium or titanium alloy and norbide is 92.5: 1 to 13.1: 1;
After the mixed powder cold compaction 1.33 * 10
