Kormeerka Tayada ee Daaweynta Kulaylka ee Saxannada Daanka Burburiyaha

Si loo hubiyo tayada daaweynta kulaylka ee saxannada daanka burburinta ee laga sameeyay birta manganese-ka sare, waa inay ku jirtaa baaritaannada adkaanta, dildilaaca, roobabka carbide-ka, kala-soocidda, iwm., waana in lagu sameeyaa si adag oo waafaqsan shuruudaha farsamada. Cilladaha sida adkaanta aan loo baahnayn ama roobabka carbide-ka, waa in dib loo sameeyaa nadiifinta xalka iyo daminta biyaha, waana in fiiro gaar ah la siiyaa hubinta in heerkulka marka la galayo biyaha uu waafaqsan yahay xeerarka.

Waa in halkan lagu ogaadaa in kala-soocidda kaarboonaynta ee shubka ay waxyeello leedahay: ka dib marka lagu qaboojiyo biyaha, lakabka la kala furfuray wuxuu isu beddelaa qaab-dhismeed martensite ah, laakiin lakabka dusha sare aad ayuu u jilicsan yahay iyadoo leh dabacsanaan aad u hooseysa, awooddiisa isku xidhka qaab-dhismeedka austenite-ka gudahana aad ayuu u liitaa. Marka ay saameyntu ku timaado xaaladaha xidhitaanka xoqidda, lakabka dusha sare si dhakhso ah ayuu u soo baxaa. Ka dib qaboojinta biyaha, lakabka la kala furfuray wuxuu maraa isbeddel martensitic ah, taasoo keenta ballaarinta mugga, halka lakabka gudaha ee birtu uu weli yahay qaab-dhismeed austenite ah. Cadaadisku wuxuu ka dhacaa lakabka dusha sare iyo lakabka gudaha, heerarka hoos u dhaca toosan ee labada qaab-dhismeedna sidoo kale way kala duwan yihiin inta lagu jiro qaboojinta dambe, taasoo horseedaysa dildilaaca dusha sare.
