Lub luag haujlwm ntawm feem ntau siv alloying ntsiab
Tom qab cov ntsiab lus alloying ntxiv rau cov hlau, qee qhov ntawm cov alloy carbides tuaj yeem tsim los kho cov nplej, txhim kho hardenability, thiab nce tempering stability kom tau raws li qhov yuav tsum tau ntawm kev hnav tsis kam thiab toughness.
Lub luag haujlwm ntawm Mn: Manganese ua kom muaj zog ntawm cov hlau, txo qhov kub ntawm martensitic transformation ntawm hlau, thiab ua kom cov khoom seem ntawm austenite tom qab quenching, uas yog qhov zoo los tiv thaiv quenching deformation, quenching tawg, thiab stabilizing qhov ntev ntawm lub workpiece. . Txawm li cas los xij, txo cov thermal conductivity ntawm steel muaj ntau dua overheating rhiab heev thiab aggravates ob hom temper brittleness. Mn yuav tsum tau ntxiv ua ke nrog Mo, V, Cr, W, thiab lwm yam. Nws yog txwv tsis pub muaj kev cuam tshuam thiab siab zog thiab toughness pwm steel.
Lub luag hauj lwm ntawm Si: Silicon tsub kom lub hardenability thiab tempering stability ntawm steel, ho txhim kho post-deformation kuj thiab cuam tshuam rau qaug zog; nws tuaj yeem txhim kho oxidation tsis kam thiab corrosion kuj ntawm steel. Txawm li cas los xij, silicon ua rau cov pa roj carbon monoxide hauv cov hlau los nag hauv daim ntawv ntawm graphite, ua rau muaj kev cuam tshuam loj heev thiab ua rau muaj kev kub ntxhov ntau dua thiab qhov thib ob temper brittleness ntawm cov hlau.
Yog tias koj muaj kev xav tau ntau ntxiv thiab cov lus nug txog steel, thov hu rau peb!
