Tempering koom nrog cov txheej txheem peb-kauj ruam hauv qhov tsis ruaj khov martensite decomposes rau hauv ferrite thiab unstablecarbides, thiab thaum kawg mus rau hauv ruaj khov cementite, tsim ntau theem ntawm microstructure hu ua tempered martensite.
Tom qab ntawd, yuav ua li cas thaum martensite tempered?
300 → 350 ° C Tempered - Martensite Embrittlement Nws yog ntaus nqi rau kev tsim ntawm cementiteparticles ntawm lub martensite lath ciam teb thiab nyob rau hauv lub laths. Thaum tempering , cov khoom coarsen thiab loj txaus kom tawg, yog li muab cov kab nrib pleb uas tuaj yeem nthuav tawm mus rau hauv matrix.
tempering hniav ua dab tsi? Tempering suav nrog cua sov hniav mus rau anon-critical kub (350 - 450 F) kom me ntsis soften thesteel (Kuv siv lub qhov cub ua noj). A tempered hniav yuav tuav ashap ntug thiab tseem khaws lub zog thiab yooj.
Ntawm no, dab tsi yog txheej txheem ntawm tempering?
Tempering hauv metallurgy, txheej txheem ntawm kev txhim kho cov yam ntxwv ntawm cov hlau, tshwj xeeb tshaj yog cov hlau, byheating nws mus rau qhov kub thiab txias, txawm tias qis dua qhov melting point, ces txias nws, feem ntau nyob rau hauv huab cua. Cov txheej txheem Nws muaj cov nyhuv toughening los ntawm kev txo qis brittleness thiab txo cov kev ntxhov siab sab hauv.
Tempered martensite embrittlement yog dab tsi?
Kev tshawb nrhiav rau cov mechanisms ntawm temperedmartensite embrittlement (TME), kuj paub tias "500 ° F" lossis "350 ° C" lossis ib kauj ruam npau taws embrittlement , tau ua nyob rau hauv kev lag luam, ultra-siab zog 4340 thiab Si-hloov 4340 (300-M) alloy steels, nrog tshwj xeeb tsom rau lub luag hauj lwm ntawm interlath films ofretained

Dab tsi ua rau lub sijhawm hloov pauv thaum lub sijhawm tempering?
300 → 350 ° C Tempered-Martensite Embrittlement Nws yog los ntawm kev tsim cov cementite particles ntawm martensite lath ciam teb thiab nyob rau hauv lub laths. Thaum lub sij hawm tempering, cov hais coarsen thiab ua loj txaus kom tawg, yog li muab cov kab nrib pleb uas yuav ces propagate mus rau hauv lub matrix
