This text computes the foundation that the home position reaction synthesizes the temperature in the thermodynamics up, the adoption machine ball whet, the vacuum heat press, the vacuum burns to knot etc. the machine metal alloy turns the powder metallurgy technique system to have the grain to strengthen the 钛基 compound material.In the process of make have, adopt the gold mutually, SEM, XRD, TEM etc. analysis the test method, to compound material and it is taking shape the tiny view organization of the each stage to turn in to carry on the analysis and researches, to make to have the TiB of to build up the analysis that the 钛基 reunited the mechanics function of the material to make the first step and discussion.
Adopt the home position synthesizes the craft system to have the TiB to build up 钛基 compound material, make use of the thermodynamics theories to the Ti and of TiB2s of home position responded to carry on the analysis, carried on to look like the calculation towards respond of burn and knot temperature, the first step assurance is in make have TiB strengthen the 钛基 reunite the material process of vacuum burn to knot the temperature as 1300 ℃s, thus draft the reasonable vacuum to burn to knot the craft, make to have the TiB to build up the 钛基 compound material.
Compound for making to have the excellent grain of a function to strengthen the 钛基 material, make compound strengthen to distribute mutually in the material even.Experiment the initial stage originally main reunited the machine ball grinder's skill of the material to carry on to investigate the analysis to the 钛基 , pass the born to build up of the home position reaction with the assurance to distribute in the body of 基 mutually even.In the process of the machine ball whet, be pound at by the ball constantly because of the admixture powder to press with 碾 , the surface of the admixture powder grain will be break constantly, combining together constantly again, will accompany with the miscellaneous quality chemical element of N, O, Fe etc. to lead to go into in this process, thus result in cleft pollute.For this, the difference carries on the machine ball to whet to the of same race and hybrid powder in the indoor temperature ball whet machine and high ability balls whet machine, prognosticating the hybrid material powder to whet the composition in the process variety in the ball, the result enunciation is in ball whet process the miscellaneous quality chemical element will whet along with the ball of carry on but enter in the hybrid powder, and these miscellaneous quality chemical elements( is a Fe particularly) lead to become member the extension that whets time along with the ball but increase.Whet to the ball at the same time in the process hybrid tiny view structure of the powder carried on the analytical research, the detection passes reasonable machine ball grinder's skill, the ball whet the process and can make the porcelain and ceramics powder is in the 基 body material the cent distribute even, thus press for the follow-up vacuum heat, the vacuum burns to knot the craft to provide the good 坯 to anticipate.
Adopt the vacuum heat to mix with the powder to carry on after press burn to knot the craft to whet to the ball with vacuum fine become the form, make the 坯 a fine degree of a body of have higher, but exist a little amount and tiny hole.Press through the vacuum heat, adopt the single stalk double toward mold to press the method to take shape hybrid powder as a body 坯 tablet, and make use of Archimedes to drain the fine degree that the method computes a body 坯 tablet or so in 94%.Place a body the 坯 tablet that the vacuum heat takes shape after press in vacuum burn knot stove to carry on the heat vacuum to burn the knot, because the chemical element of 钛 is very cheery, was easiest oxidize, so the tablet of 坯 wants to keep the higher vacuum degree always in the process of carry on vacuum burn knot, experimenting a control of the lieutenant general vacuum at the origin or so in 103 Pases of -s.Moreover, because of after the vacuum heat press of the 坯 an existence of a body have the small hole, will accompany with to put the spirit necessarily in burn knot process, so in burn knot process should at try the kind to put to annoy the appropriate control of stage to burn to knot the temperature to go up the speed, to reduce the on trial pollution.Pass the calculation, after vacuum burn the knot of on trial and fine degree can attain 98% above.
Adopt the gold mutually, XRD, TEM etc. analysis after the test method burn the knot to the vacuum of tried the kind to carry on the tiny view organization analysis.XRD the analytical result enunciation at burn the knot through the heat of 1300 ℃s, admixture material in the TiB2 and the 基 body materials that beginning start to joins respond completely, born strengthen mutually TiB, fit together with calculating result of thermodynamics mutually.Gold mutually and the TEM analytical result express after vacuum burn knot, the compound exists the obvious to build up in the material mutually TiB, and strengthen the body to present the 晶 beard form, 晶 beard the diameter is or so for 0.5 μ ms, lengths in 60 μ ms, strengthenning to distribute in the body of 基 mutually more even, is neat and clean with an interface of the body of 基 .
Carry on the indoor temperature compression to experiment towards making to have the TiB of strengthen the 钛基 reunite material, experiment the result enunciation:The compression that reunites the material accepts defeat the strength or so in the 1320 Mpas, compare the 基 body material of compression function had the obvious exaltation, but the extension rate of the material is opposite to lower.
