Efter sista kallvalsningssteget utföres en slutglödgzxing för att ge materialet eftersträvade mekaniska egenslæper. Slutglödgrzingen kan göras vid temperaturer av 400-700 OC. ' Rör som framställts av Zircaloy under hittills använda betingelser har i allmänhet visat sig 'besitta tillräcklig beständigiiet mot korrosion under de driftsbetingelser som råder i en kârnrealctor. Utvecklingen går emellertid mot ett allt högre utnyttjande av bränslet, vilket betyder längre drifts- tider för bränsleelementen. Kapslingsmaterialet kommer därmed att utsättas för det korrosiva vattnet under en längre tidsperiod än vad som tidigare varit normalt, vilket innebär en ökad risk för korrosionsskador. Det har där- för varit ett önskemål att åstadkomma bättre korrosionsegenskaper hos de an- vända legeringarna utan att detta medför ogynnsernna förändringar; av de meka- niska egenskaperna. 15 20 25 30 55 s1o421s-7 2 in a number of steps and between two. successive .. cold rolling an annealing, intermediate annealing, at 625-700 0G to enable the subsequent cold rolling. After the last cold rolling step, a final annealing is performed to give the material the desired mechanical natural drag. The final annealing can be done at temperatures of 400-700 OC. 'Pipes manufactured by Zircaloy under the conditions used hitherto have generally been found to possess sufficient corrosion resistance under the operating conditions prevailing in a nuclear reactor. However, the trend is towards ever higher utilization of the fuel, which means longer operating times for the fuel elements. The encapsulation material will thus be exposed to the corrosive water for a longer period of time than was previously normal, which entails an increased risk of corrosion damage. It has therefore been desired to achieve better corrosion properties of the alloys used without this leading to unfavorable changes; of the mechanical properties.
Det är tidigare känt, bl a genom den amerikanska patentskriften 4 238 251, att man genom /å-släclcning av ett färdigtillverkat rör av Ziroaloy kan för- bättra rörets beständighet mot s k accelererad nodulär korrosion i vatten och ånga av högt tryck. Rör av Zircaloy med goda mekaniska egenskaper kan, såsom framgår av den amerikanska patentskriften 3 865 655, åstadkommas genom ß-släckning av den extruderade produkten, innan denna underkastas den sista kallvalsningen. 'I Den exakta orsaken till den förbättrade beständigheten mot accelererad nodu- korrosion som uppnås genom ß -släokning har ännu inte helt klarlagts.It is previously known, inter alia from U.S. Pat. No. 4,238,251, that by extinguishing a prefabricated Ziroaloy pipe, the resistance of the pipe to so-called accelerated nodular corrosion in water and high-pressure steam can be improved. Zircaloy tubes with good mechanical properties can, as shown in U.S. Pat. No. 3,865,655, be made by β-quenching the extruded product before it is subjected to the final cold rolling. The exact cause of the improved resistance to accelerated nodal corrosion achieved by ß -leaching has not yet been fully elucidated.
Det anses dock att förbättringen är relaterad till storlek och fördelning av intermetalliska föreningar i materialet. De intermetalliska. föreningarna, s k sekundärfaser, utgöres av kemiska föreningar innehållande förutom zirkonium främst elementen jm, krom och nickel och de förekommer i form av partiklar.However, it is considered that the improvement is related to the size and distribution of intermetallic compounds in the material. The intermetallic. the compounds, so-called secondary phases, consist of chemical compounds containing in addition to zirconium mainly the elements jm, chromium and nickel and they occur in the form of particles.
Den vid fi-släokning åstadkomna upplösnings- och återutskiljningsprocessen resulterar dels i en förfining av partiklarnas storlek, dels i en omfördel- ning från jämnt fördelade partiklar till partiklar utgörande stråk i de vid /å -fasomvandlingen bildade »L -kornens korngränser.The process of dissolution and re-precipitation produced by fi-slurrying results partly in a refinement of the particle size, and partly in a redistribution from evenly distributed particles to particles constituting streaks in the grain boundaries of the »L -grains formed during the / å phase conversion.
En ß-släclming av det färdiga kapselröret medför en sänkning av duktili- teten hos röret, vilket innebär en nackdel hos metoden. En ß -släckning av den extruderadeprodulcten före kallvalsning till färdigdimension ger 10 15 20 25 30 8104213-7 mindre försämringar av det färdiga rörets mekaniska. egenskaper. En /b-släck- ning ger oavsett om det sker på ett färdigtillverkat rör eller före det sista kallvalsningssteget emellertid en utbytesförsämring på grund av ökad kassa- tion och vidare materialförluster på. grund av att ß-släclming medför bild- ning av ett oxidskikt på. rörets yta, som Jnåste avlägsnas.A ß-slackening of the finished capsule tube entails a lowering of the ductility of the tube, which entails a disadvantage of the method. A ß-extinguishing of the extruded product before cold rolling to finished dimension gives minor deteriorations of the mechanical of the finished tube. characteristics. A / b extinguishing, regardless of whether it takes place on a finished pipe or before the last cold rolling step, however, results in a deterioration in yield due to increased disposal and further material losses. due to the fact that ß-slamming leads to the formation of an oxide layer on. the surface of the tube, from which Jnåste is removed.
Enligt den föreliggande uppfinningen har det visat sig möjligt att tillverka kapselrör för bränsleetavar till kärnreaktorer, som har minst lika god resis- tens mot nodulär korrosion som de 'bästa tidigare kända kapselrören och sam-- tidigt en bättre duktilitet än sådana kapselrör. I jämförelse med tidigare kända tillverlmingsmetoder för kapselrör under användning av /5 -släclming efter extrusionen erhålles vid användning av den föreliggande uppfinningen, som också. irmefattar en /å-släolming, en utbytesförbättrizzg på grund av minskad kassation ooh vidare minskade materialförluster på. grund av att bildade oxider kan avlägsnas på en mindre yta genom ett /å-släokningen ut- föres i"ett tidigare skede av tillverkningsprocessen.According to the present invention, it has been found possible to manufacture canister tubes for fuel rods for nuclear reactors which have at least as good resistance to nodular corrosion as the best known canister tubes and at the same time a better ductility than such canister tubes. In comparison with prior art production methods for canister tubes using β-slurry after extrusion are obtained using the present invention, which also. includes a / å släolming, a yield improvement due to reduced scrap ooh further reduced material losses on. due to the fact that formed oxides can be removed on a smaller surface by the one / å sludge increase is carried out at an earlier stage of the manufacturing process.

The β-elimination of the extruded product is carried out by heating the product to a temperature in the ß-phase range, suitably to a temperature of 950-1250 ° C and preferably to a temperature of 1000-1150 ° C and then rapidly to a temperature in the oC phase range.

Vid tillverkning av kapselrör enligt den föreliggande uppfinningen har 'det visat sig, att sekundarfaspartiklarnas storlek i det färdiga kapselröret, liksom fallet är då /å-släcknjng användes, är avsevärt mindre än vid konven- tionell tillverkning av kapselrör utan [å-släclming efter extrusionen. Se- kundärfaspartiklarna ligger dock i motsats till vad fallet är efter ß-släck- ning vid tidigare kände metoder homogent fördelade i' materialet. Det är tänk- bart att det är den enligt den föreliggande uppfinningen uppnådda lilla stor- leken hos sekundärfaspartiklarna tillsammans med den homogena fördelningen av dem som ger den gynnsamma kombinationen av god resistens mot nodulär korrosion och goda. mekaniska egenskaper.In the manufacture of canister tubes according to the present invention it has been found that the size of the secondary phase particles in the finished canister tube, as is the case when / å-extinguishing is used, is considerably smaller than in conventional manufacture of canister tubes without [å-extinction after extrusion . However, the secondary phase particles are in contrast to what is the case after ß-quenching with previously known methods homogeneously distributed in the material. It is conceivable that it is the small size of the secondary phase particles achieved according to the present invention together with the homogeneous distribution of them which gives the favorable combination of good resistance to nodular corrosion and good. mechanical characteristics.
