Qhov txawv ntawm Zr702 thiab Zr705 yog dab tsi?
Thaum Zr702 thiab Zr705 yog ob qho tib sizirconiumalloys nrog cov khoom zoo sib xws, muaj qhov sib txawv tseem ceeb ntawm lawv uas cuam tshuam rau lawv qhov tsim nyog rau kev siv tshwj xeeb.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm Zr702 thiab Zr705 yog lawv cov muaj pes tsawg leeg. Zr702 muaj yuav luag ntshiab zirconium, tsuas yog ib qho me me ntawm hydrogen ntxiv los txhim kho nws cov khoom siv kho tshuab. Zr705, ntawm qhov tod tes, muaj cov ntsiab lus ntxiv xws li niobium, tin, thiab oxygen, uas tau ntxiv los txhim kho nws qhov kub thiab txias zog.
Lwm qhov sib txawv tseem ceeb ntawm ob lub alloys no yog lawv lub zog txhua yam. Zr702 muaj ductility zoo heev thiab tuaj yeem tsim tau yooj yim rau hauv ntau hom duab, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau qib siab ntawm kev hloov pauv. Nyob rau hauv kev sib piv, Zr705 yog ib tug muaj zog, stiffer cov ntaub ntawv zoo dua haum rau cov kev siv uas high-temperature zog thiab nruj yog qhov tseem ceeb. Lub zog tensile thiab tawm lub zog ntawm Zr705 yog ntau dua li ntawm Zr702. Koj tuaj yeem tshawb xyuas cov lus hauv qab no rau kev sib piv ntxiv ntawm Zr702 thiab Zr705.
