1. Xalka Daaweynta Kulaylka
Tilmaamaha guud ee daaweynta kulaylka xalku waa: kululaynta shubista ilaa 950 ° C - 1175 ° C iyo ku dhejinta biyaha, saliidda ama hawada ka dib ilaalinta kulaylka si ay si buuxda u milaan karbides-ka birta aan la taaban karin si loo helo qaab dhismeed hal-waji ah. Doorashada heerkulka xalku waxay kuxirantahay kaarboonka ku jira birta kabka ah. Mar kasta oo ay ka kooban tahay kaarboonka, ayaa sare u kacaysa heerkulka xalka adag ee loo baahan yahay.
Si loo yareeyo farqiga heerkulka u dhexeeya dusha sare ee dhejinta birta iyo xudunta inta lagu jiro habka kuleylka, habka kuleylka ee daaweynta xalka birta austenitic waa in lagu sii kululeeyaa heerkul hooseeya ka dibna si dhakhso ah u kululee heerkulka xalka. Waqtiga haynta waa inuu u kordhaa si u dhigma marka dhumucda darbiga wax lagu shubayo uu kordho.
Dhexdhexaadinta qaboojinta ee daaweynta xalku waxay noqon kartaa biyo, saliid ama hawo, kuwaas oo biyaha inta badan la isticmaalo. Qaboojinta hawadu waxay ku haboon tahay oo kaliya tuurista birta dhuuban.

2. Xasilinta
Austenitic birta aan lahayn waxay leedahay iska caabin aad u wanaagsan oo daxalka ah ka dib daaweynta xalka. Si kastaba ha ahaatee, marka shubista dib loo kululeeyo ilaa 500°C-850°C ama shubista ay ka shaqeyso inta u dhaxaysa heerkulkan, chromium carbide ayaa dib ugu soo da'i doonta xadka hadhuudhka Austenite, taasoo keenaysa daxalka xadka hadhuudhka ama dildilaaca alxanka. Dhacdadan waxa loo yaqaan dareenka. Si loo hagaajiyo iska caabbinta daxalka intergranular ee sida austenitic ahama, waxaa guud ahaan lagama maarmaan ah in lagu daro walxaha alloying sida titanium iyo niobium. Daawaynta xalka ka dib, ku celi ilaa 850 ° C - 930 ° C, ka dibna si dhakhso ah u qabooji. Sidan oo kale, carbides ee titanium iyo niobium ayaa marka hore ka soo da'aya austenite, taas oo ka hortagaysa roobabka chromium carbide iyo hagaajinta iska caabbinta daxalka xadka hadhuudhka ee birta aan lahayn.
