Cilladaha iyo ka-hortagga been-abuurka waaweyn: Qaab-dhismeedka yar-yar ee aan sinnayn iyo guryaha

Faallooyinka waaweyn, Sababo la xiriira cabbirkooda weyn, hababka badan, wareegga dheer, nonformity ee habka, iyo arrimo badan oo aan xasilloonayn, inta badan sababa labbiska daran ee microstructure ah, si aanay u gudbi karin imtixaanka hantida farsamo, kormeerka metallographic iyo non- ogaanshaha cillad wax burburisa.

Sababtoo ah kala-soocidda halabuurka kiimikada, isku-darka isku-darka iyo cilladaha daloolada kala duwan ee ku-meel-gaadhka ah;
Marka kululaynta, heerkulku si tartiib tartiib ah ayuu isu beddelaa, qaybintu waa mid aan sinnayn, diiqada gudaha waa weyn tahay, cilladdu waa badan tahay;
Heerkulka sare iyo waqti dheer oo been abuur ah, walbahaarka maxalliga ah iyo qallafsanaanta maxalliga ah, heerka socodka caagga ah, heerka isugeynta, qaybinta qallafsanaanta ayaa aad u kala duwan;
Inta lagu jiro qaboojinta, habka faafintu waa mid gaabis ah, isbeddelka unuggu waa mid adag iyo walbahaarka dheeraadka ah waa mid weyn.
Dhammaan arrimaha kor ku xusan waxay u horseedi karaan isku dheelitir la'aanta waxqabadka unugyada iyo tayada aan u qalmin.
Tallaabooyinka lagu hagaajinayo isku-duubnidafoorjaro waaweyn:
1. La qabso tignoolajiyada sareeysa ee dhalaalinta si loo hagaajiyo tayada birta ee birta dhalada;
2. La qabso kontoroolka been abuurka, xakamaynta tignoolajiyada qaboojinta, wanaaji habka farsamada, iyo hagaajinta heerka farsamada iyo dhaqaalaha ee wax soo saarka weyn ee been abuurka.
