Kev siv Tantalum Scrap hauv Alloys

Daim ntawv thov ntawm tantalum raws li ib tug alloying caij nyob rau hauv steel yog tseem tsawg heev. Tantalum muaj affinity siab heev nrog interstitial atoms nyob rau hauv steel xws li C, N, thiab lwm yam, thiab cov tebchaw tsim nrog lawv yog heev ruaj khov txawm nyob rau hauv high kub.

Cov kws tshawb fawb los ntawm Lub Tsev Kawm Ntawv ntawm Kev Tshawb Fawb Hlau, Suav Academy ntawm Kev Tshawb Fawb tau kawm ua ntej txog kev txhawb zog thiab cov txheej txheem cuam tshuam ntawm tantalum ntawm Fe-C-Ta alloys los ntawm kev ntsuas cov cuab yeej cuab tam thiab OM, SEM, thiab TEM kev soj ntsuam. Cov txiaj ntsig kev tshawb fawb pom tau tias thaum cov ntsiab lus ntawm tantalum seem nce los ntawm 0.027 feem pua ​​​​rau 0.059 feem pua ​​, lub zog ntawm cov alloy yog zoo heev, thiab cov cuam tshuam lub zog ntawm cov alloy nrog siab tantalum ntsiab lus txo los ntawm 87J, tab sis nws tseem muaj zog toughness. Kev tshuaj xyuas qhia tau hais tias qhov kev txhawb zog ntawm tantalum hauv cov hlau-raws li alloys yog sawv cev los ntawm cov tshuaj tiv thaiv kom muaj zog thiab nag lossis daus. Tom qab lub siab tantalum cov ntsiab lus alloy yog hnub nyoog ntawm 600 degree rau 1 h, nws lub zog thiab plasticity ncav cuag qhov siab tshaj plaws nyob rau tib lub sijhawm, thiab qhov zoo tshaj plaws tantalum-muaj carbide tau txais. nag lossis daus strengthening nyhuv.
