Li-carbide tsa mantlha, li-carbide tse nang le granular ke li-carbide tsa bobeli tse tsoang ho austenite nakong ea ho futhumatsa, 'me litaba tsa carbide ke 3.6%. lipatlisiso li bontša:

1. Mocheso o tima o ama ho felisoa ha carbides. Ha mocheso o tima o ntse o eketseha, likarolo tsa carbide tse mohahong o tima oa moqolo oa tšepe e phahameng li fokotseha butle-butle. Ha mocheso o phahama ho fihla ho 1200 ℃, carbide ea granular e hlile e qhibilihile
2. Tharollo, ho setse feela palo e nyane ea carbide e kholo.
3. Ha mocheso o timang o ntse o eketseha, lithollo tsa tšepe e lebelo li tsoela pele ho hola. Ha mocheso o tima o feta 1040 ° C, mokhoa oa kholo ea lijo-thollo o totobetse, mocheso o tima o feta 1160 ° C, boholo ba lijo-thollo bo fihla ho 4.5, 'me ho fifala ha lijo-thollo ho tebile haholo.
4. Ha mocheso o tima o ntse o eketseha, litaba tsa austenite tse bolokiloeng li ntse li tsoela pele ho eketseha. Ha mocheso o tima o ka tlase ho 1080 ° C, litaba tsa austenite tse bolokiloeng li eketseha butle butle, ebe litaba tsa eona li eketseha haholo. Ha mocheso o tima o fihla ho 1160 ℃, litaba tse bolokiloeng tsa austenite li nyolohela ho 38%. Ka hona, ho latela pono ea taolo ea litaba tse bolokiloeng tsa austenite, mocheso o tima o lokela ho ba tlase ho feta 1080 ℃.
5. Ha o tima ka 1040 ℃, thatafala fihla boleng tlhōrōng, ho fihlela ho 64.1HRC. Nakong ena, sebopeho sa moqolo oa tšepe o lebelo le holimo, boholo ba lijo-thollo, le litaba tse bolokiloeng tsa austenite li tšoana hantle ka ho fetisisa.
6. Mocheso o tima oa thepa e ncha e entsoeng ka lebelo le phahameng ea tšepe e lokela ho khethoa lipakeng tsa 1020 ～ 1080 ℃.
