Middiyaha Jikada Ruitai: Ilahaaga Premier ee Midiyaha Jikada ee Gaarka ah ee laga sameeyay Shiinaha
Sameynta qaababka mindiyaha Dimishiq waxaa inta badan sabab u ah habka been abuurka ee gaarka ah iyo saamiga alaabta ceeriin.
Ugu horreyntii, alaabta ceeriin ee lagu sameeyo mindiyaha Dimishiq waa bir ka kooban kaarboon kala duwan. Goynta iyo saami qaybsiga ka dib, birahani waxay noqonayaan kuwo ku habboon samaynta cabbirrada. Kadibna, birtahan waxaa lagu dhejiyaa foorno heerkul sare ah waxaana lagu kululeeyaa heerkul sare, oo noqda mid jilicsan oo sahlan in la foorarsado. Inta lagu guda jiro habka been abuurka, birtumihiisu waxa uu isticmaalaa dubbe weyn oo been abuur ah si uu si isdaba joog ah u laalaabo oo u garaaco alaabta ceeriin, si ay si tartiib tartiib ah u noqdaan mindi maran. Habkan foorjarida ah ee isku laabma ayaa ka dhigaysa birta kala duwan inay soo bandhigaan iftiin kala duwan iyo midabyo mugdi ah seefaha la dhammeeyey, taas oo ah qaabka quruxda badan ee aan aragno.
Xitaa ka sii gaar ah ayaa ah habka qalloocinta ee sida caadiga ah loo isticmaalo mindiyaha Dimishiq. Habkan been abuurka ah waa in la isku laalaabo lakabyo badan oo bir ah oo kala duwan oo loo rogo qaab maroojin ah, ka dibna loo sameeyo oog siman. Habkan been-abuurka ah waxa uu soo saari karaa "xariijimo qalloocan", taas oo ah, xariijimo ama dildilaacyo ay samaysay sibidh loo habeeyey dhinaca leexinta. Habka qallooca ayaa soo bandhigi kara habab kala duwan iyadoo loo eegayo xagasha qalloocan, jihada qalloocinta, nambarka maroojinka iyo arrimo kale, sida xariiqyo toosan, dooxooyin, xariiqyo wareeg ah, xariiqyo baalal ah, iwm.
Marka laga soo tago geeddi-socodka been-abuurka, roobabka iyo qaybinta sibidhka inta lagu jiro geeddi-socodka been-abuurka ayaa sidoo kale door muhiim ah ka ciyaara sameynta qaabka. Cementite waxay ku soo degi kartaa xadka hadhuudhka austenite ama xudunta eutectic, oo waxay samaysaa qaybin meelo kala duwan oo leh waqtiyo iyo habab kala duwan, taasoo sii kobcinaysa qaabka qaabka.
Guud ahaan, qaabka loo sameeyo mindiyaha Dimishiq waa hab-socod bir ah oo adag, kaas oo ku lug leh kala-soocidda curiyeyaasha badan, beddelka wejiyada badan iyo hawlgallada been-abuurka badan. Nidaamkan gaarka ah wuxuu ka dhigayaa mid kasta oo Dimishiq ah inuu yeesho qaab u gaar ah, isagoo noqday hanti farshaxan oo midiyaha dhexdooda ah.
