But the deposited Ti of laser gain material manufacturing technology preparation2AlNb based alloy tissue is markedly different from traditional forging Tissue is made, coarse B2 phase crystal grain (more than 200 μm) leads to deposited Ti2AlNb based alloy plasticity is poor, is not able to satisfy reality The demand of border application, it is therefore desirable to which one kind manufactures deposited three-phase Ti for laser gain material2The heat treatment process of AlNb based alloy, Under the premise of meeting strength character, its plasticity is improved.
Summary of the invention
The purpose of the present invention is to provide one kind to manufacture three-phase Ti based on laser gain material2The heat treatment work of AlNb based alloy Skill makes moulding material on the basis of proof strength performance, improves plasticity, manufactures three-phase Ti for laser gain material2AlNb based alloy Practical application establish technical foundation.
To achieve the above object, the present invention takes following technical scheme:
A kind of laser gain material manufacture three-phase Ti2The heat treatment process of AlNb based alloy.The technique is in Ti2AlNb based alloy The solid solution of the monophase field B2, eliminates the α in B2 matrix2Mutually and O phase, crystal boundary and transgranular there is a small amount of α in cooling procedure2Mutually generate；Subsequent B2 + O two-phase section is kept the temperature, crystal boundary and transgranular α2It mutually remains, and part α in heat treatment process2Phase transition is O phase, the phase Change process forms O phase in rich Nb element area along with the diffusion of Nb element.The concrete form of phase transformation is α2Mutually wrapped with B2 phase Analysis reaction is changed into O phase.After heat treatment, B2 is transgranular in addition to α2Phase, there are also largely in grayish lath-shaped O phase, O phase size is big It is small different.Large scale O phase is to retain after B2+O two-phase section high-temperature process, can be also precipitated after B2+O two-phase section low-temperature treatment a large amount of small Size O phase forms double size tissues.Compared with deposited, matrix precipitate is grown up obviously, and Grain Boundary Precipitates width is suitable.
In the present invention, the three-phase Ti of laser gain material manufacture2The heat treatment process of AlNb based alloy the following steps are included:
Step 1: laser gain material is manufactured into three-phase Ti2The thin wall product is put into heating by AlNb based alloy thin wall product In furnace, with stove heating to 1100 DEG C, 0.5-1h is kept the temperature, room temperature is then cooled to；
Step 2: the thin wall product Jing Guo step 1 is put into heating furnace, with stove heating to 920 DEG C, keeps the temperature 2h, It is then cooled to room temperature；
Step 3: the thin wall product Jing Guo step 2 is put into heating furnace, with stove heating to 800 DEG C, keeps the temperature 18- For 24 hours, then it is cooled to room temperature.
Further, the three-phase Ti2AlNb based alloy thin wall product has the Ti of laser gain material manufacture2AlNb based alloy Deposited α2+ B2+O three-phase contexture.
Further, heating furnace used is chamber type electric resistance furnace in step 1, accuracy of temperature control ± 5 DEG C, heating rate is 10 DEG C/ Min, the type of cooling are air-cooled.
It being further limited as of the invention, heating furnace used is chamber type electric resistance furnace in step 2, accuracy of temperature control ± 5 DEG C, Heating rate is 10 DEG C/min, and the type of cooling is air-cooled.
It being further limited as of the invention, heating furnace used is chamber type electric resistance furnace in step 3, accuracy of temperature control ± 5 DEG C, Heating rate is 10 DEG C/min, and the type of cooling is air-cooled.
The beneficial effects of the present invention are:
A kind of laser gain material manufacture three-phase Ti is provided2The heat treatment process of AlNb based alloy, laser gain material manufacture three-phase Ti2AlNb based alloy is after monophase field solution treatment, α2With O phase back dissolving into matrix, large scale O is formed after the processing of B2+O two-phase section The double size tissues mutually coexisted with small size O phase.The α retained in alloy2Mutually be conducive to the promotion of alloy strength；Transgranular O phase is sent out Apparent roughening is given birth to, phase interface reduces, weakens the strengthening effect of precipitated phase, increase passability when dislocation motion, make Material is obtained while keeping some strength, plasticity, intensity and plasticity excellent combination property greatly improved.
