Lub zog Aspect

 

Khoom - Solution Strengthening Effect: Manganese tuaj yeem tsim cov khoom siv - cov tshuaj ntxiv dag zog rau hauv nkoj tsim steel daim hlau. Thaum manganese atoms yaj nyob rau hauv cov hlau matrix, lub lattice ntawm cov hlau yuav distorted. Qhov no lattice distortion yuav impede lub zog ntawm dislocations, thiab lub zog ntawm dislocations yog lub microscopic mechanism ntawm yas deformation ntawm cov ntaub ntawv. Yog li ntawd, qhov kev cuam tshuam ntawm kev txav mus los ua rau nws nyuaj rau cov nkoj tsim cov hlau daim hlau kom tau txais cov yas deformation nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, yog li ua kom muaj zog yield thiab tensile lub zog ntawm cov hlau. Piv txwv li, thaum lub nkoj tsim dais sab nraud quab yuam xws li qhov hnyav ntawm cov khoom thauj thiab kev cuam tshuam ntawm cua thiab nthwv dej, kev txhim kho lub zog los ntawm manganese cov ntsiab lus pab tswj cov duab thiab kev ncaj ncees ntawm lub nkoj daim hlau.

 

Nplej - Refining Effect (Indirect): Manganese pab ua kom cov nplej kom zoo rau qee yam. Thaum lub sij hawm solidification thiab ua cov hlau, manganese tuaj yeem hloov cov qauv kev loj hlob ntawm cov nplej. Txawm hais tias nws tsis yog cov nplej tseem ceeb - ua kom zoo zoo li micro - alloying cov ntsiab lus (xws li vanadium, niobium, thiab titanium), qhov tsim nyog ntawm manganese tuaj yeem tswj cov qoob loo loj rau qee yam los ntawm kev cuam tshuam rau theem - kev hloov pauv tus cwj pwm thiab lwm yam. Ib qho loj me me txhais tau hais tias cov qoob loo nce ntxiv - thaj tsam ntawm thaj tsam, thiab cov ciam teb yog ib qho kev cuam tshuam rau kev txav mus los, uas ua rau muaj kev cuam tshuam ntxiv ntawm kev txav mus los thiab yog li ua kom lub zog ntawm cov nkoj tsim steel phaj.

Toughness Aspect

 

Txo qhov kub brittleness: Nyob rau hauv cov txheej txheem ntawm shipbuilding steel daim hlau, leej faj yog ib qho teeb meem uas tuaj yeem ua rau kub brittleness ntawm hlau. Manganese tuaj yeem ua ke nrog sulfur los ua manganese sulfide (MnS). Kev tsim ntawm manganese sulfide yog qhov muaj txiaj ntsig zoo vim tias nws tuaj yeem kho cov sulfur thiab tiv thaiv cov sulfur los ntawm cov uas twb muaj lawm nyob rau hauv lub xeev dawb thiab ua rau lub embrittlement ntawm hlau thaum kub ua hauj lwm (xws li dov). Nyob rau hauv txoj kev no, manganese indirectly txhim kho lub toughness ntawm shipbuilding steel daim hlau, tshwj xeeb tshaj yog toughness nyob rau hauv kub - ua hauj lwm thiab kub - siv ib puag ncig.
