I-Austempering kukunciphisa ukuguqulwa kombhobho wentsimbi kunye nendlela esebenzayo yokucima i-Jian crack, kodwa indlela yokusebenzisa ngokufanelekileyo indlela yenkqubo kufuneka isekelwe kwizinto eziphathekayo ezingenamthungo zentsimbi, ubungakanani, ubulukhuni kunye nokuqina, iimfuno zokuguqulwa, kunye neemeko ezithile zokusebenza. ukhetho luya kuba yi-Isotherml yokucima iingxaki ezifuna ingqalelo zishwankathelwa ngolu hlobo lulandelayo:
[1] Ezifana carbon steel kunye nezinye ezantsi ukuqina ukuqina intsimbi austempering quenching ukuqina, kufuneka ifanele ukunyusa ubushushu ukucima, H kukwandisa uzinzo austenite ukuphepha nokuthintela ukwenzeka high-ubushushu non-iqokobhe kwi an Ukucima inkqubo yokutshintsha umzimba.

[2] Austempering zithintelwe intsimbi kunye nobungakanani umbhobho. Ngexesha austempering quenching quenching, umgaqo osisiseko kukuqinisekisa ukuba utshintsho alwenzeki intsimbi engenamthungo lobushushu eliphezulu kwinkqubo yokupholisa, kwaye ke ngoko ubukhulu ingenamthungo amabakala umbhobho steel intsimbi kunye nempembelelo ngqo kumgangatho wokucinywa austempering quenching, jikelele iimfuno umbhobho carbon steel ingenamthungo esebenzayo ubukhulu kufuneka ibe ngaphantsi kwe-5mm, ubukhulu obusebenzayo ingxubevange kufuneka ibe ngaphantsi kwe-30mm. Ukususela kumbono womxholo wekhabhoni kwi-0.4% ukuya kwi-0.6% yekhabhoni ayifanelekanga ukuba i-austempering, iphezulu kune-0.6% okanye ngaphezulu kwe-carbon steel ukuya kwi-austempering quenching.

[3] Ubushushu kunye nexesha kufuneka zisekelwe austempering ukuqina lukhuni iimfuno ukusebenza umbhobho yentsimbi engenamthungo, ebhekisela intsimbi C-gophe uzimisele, ngokomgaqo, yonke iaustenite iguqulwa ibe bainite, kwindawo yokupholisa ngokuqhelekileyo isisombululo nitrate bath ukuze ukuqinisekisa ubushushu obuzinzileyo, isixhobo sokupholisa kufuneka songezwe phakathi ukuthintela ukwanda kweqondo lobushushu eliphakathi kuchaphazela umgangatho wokucima. Ukwengeza ubude bexesha lobushushu kufuneka liququzelele inguquko yombhobho wentsimbi ongenamthungo njengomlinganiselo, ukusebenza ixesha elide kuncitshisiwe, ngoko ke kufuneka kuthathelwe ingqalelo.

[4] Intsimbi eqinisayo eyomelezayo kwaye abanye basenokungacaphuki. Kodwa ngenxa yokuqina komzimba we-workpiece, i-austenite yangaphakathi eshiyekileyo iya kutshintshwa kwinkqubo yokupholisa umoya elandelayo yi-martensite, kufuneka ihlanjululwe, injongo kukuphelisa ukunyanzeliswa kunye nozinzo irula yentsimbi engenamthungo, qaphela ubushushu bokufudumala kufuneka bube. ngaphantsi kobushushu obuphantsi.
