This article in thermodynamics computation home position response synthesis temperature foundation, used the mechanical ball grinding, the vacuum thermo-compression, the vacuum agglutinates and so on the mechanical alloy powder metallurgy technology to prepare the pellet enhancement titanium base compound materials. In the preparation process, uses the gold, analysis test method and so on SEM, XRD, TEM, and its was forming each stage to the compound materials the microscopic organization to evolve has carried on the analysis and the research, to the TiB enhancement titanium base compound materials mechanics performance which prepared has made the preliminary analysis and the discussion.
Uses the home position synthesis craft to prepare the TiB enhancement titanium base compound materials, the use thermodynamics theory to between Ti and the TiB2 home position responded has carried on the analysis, agglutinated the temperature to the response to carry on the approximate calculation, the preliminary determination in prepared in the TiB enhancement titanium base compound materials process the vacuum to agglutinate the temperature is 1,300 ℃, thus drew up the reasonable vacuum to agglutinate the craft, prepared the TiB enhancement titanium base compound materials.
In order to prepare the performance outstanding pellet enhancement titanium base compound materials, makes in the compound materials to strengthen distributes evenly. This experimental initial period mainly has carried on the exploration analysis to the titanium base compound materials mechanical ball grinding craft, by guaranteed through the home position responded the production the enhancement distributes evenly in the substrate. In in mechanical ball grinding process, because the mix powder receives the ball unceasingly the impact and the roller compaction, the mix powder pellet surface can destroy unceasingly, also can unify unceasingly in together, can follow impurity element the and so on N, O, Fe in this process introduction, thus causes the gap pollution. Therefore, separately has carried on the mechanical ball grinding in the room temperature ball mill and the high energy ball mill to the homogeneous mix powder, observed the mix material powder in ball grinding process ingredient change, finally indicated the impurity element can carry on in the ball grinding process along with the ball grinding but enters in the mix powder, moreover these impurity elements (in particular Fe) the introduction can lengthen along with the ball grinding time but increases. Meanwhile mixed the powder to the ball grinding process in the microscopic structure to conduct the analysis research, discovered through the reasonable mechanical ball grinding craft, the ball grinding process might cause the ceramic powder a minute distribution to be even in the substrate material, thus for the following vacuum thermo-compression, the vacuum agglutinated the craft to provide the good semifinished materials.
Uses the vacuum thermo-compression and the vacuum agglutinates the craft to mix the powder after the ball grinding to carry on the compact forming, prepares the block body semifinished product spindle sends the density to be high, but has the few micro holes. Through the vacuum thermo-compression, will use the single axle bidirectional mould pressing method to mix the powder forming for the block body semifinished product spindle, and will calculate the block body semifinished product spindle using the Archimedes drainage to send the density about 94%. The block body semifinished product spindle forms which after the vacuum thermo-compression lays aside in the vacuum sintering furnace carries on the high temperature vacuum to agglutinate, because the titanium element is extremely lively, is extremely easily oxidized, therefore semifinished product spindle in carries on in the process which the vacuum agglutinates to have to maintain the high vacuum degree throughout, in this experiment vacuum degree control about 10 - 3Pa. Moreover, after because the vacuum thermo-compression block body semifinished product spindle existence has the small hole, in agglutinates in the process to be able to follow surely is deflating, therefore in agglutinates in the process to be supposed to deflate the stage suitable control in the test specimen to agglutinate the temperature to elevate the speed, by reduces experimental the pollution. Through the computation, the vacuum agglutinates the after experiment to send the density to be possible to achieve above 98%.
Used the gold, analysis test method and so on XRD, TEM agglutinates the after test specimen to the vacuum to carry on the microscopic organization analysis. The XRD analysis result indicated in passes through 1,300 ℃ high temperatures to agglutinate, in the mix material initial joins TiB2 and the substrate material responded completely, the production strengthens TiB, tallies with thermodynamics computation result. The gold and the TEM analysis result indicated agglutinates after the vacuum, in the compound materials has obvious enhancement TiB, and strengthens the body to assume the crystal to have the shape, the crystal to have the diameter to be 0.5 mu m, the length about 60 mu m, the enhancement distributes in the substrate evenly, with the substrate between the contact surface smooth, is clean.
To the TiB enhancement titanium base compound materials which prepares carry on the room temperature compressive test, the test result indicated that, The compound materials compression yield strength about 1320Mpa, compared the substrate material the compression performance to have the distinct enhancement, but the material elongation ratio reduced relatively.
