I-Shrinkage and Loeseness
Uhlobo olufanayo lokuphazamiseka kohlobo olungenalutho, ukugcwaliswa kwevolumetric ngokuqinile akwanele, kuphela ukwakheka kanti indawo esenzakalelayo ihlukile .
Shrinkage cavity
Ngokuvamile, ukuqina kokuphonswa kwemali akuwona ekugcineni, kwakha umgodi we-tubular noma wegatsha elifana nendawo enkulu .
-Ngakhulekiwe
Ngokuvamile, kunama-pores amancane futhi ahlakazekile phakathi kwama-dendrites, aphumela ekusondeni kwesakhiwo sangaphakathi se-castring {{0} Ukulangazelela okungabonakala ngaphansi kwesibonakhulu kuba ukulangazelela ama-microscopic
Ukuqhekeka kwe-cast
Ngesikhathi senqubo yokuqina, ngenxa ye-shrinkage ye-shrinkage, ukucindezela okukhulu kwangaphakathi kuyakhiwa kancane kancane, futhi ukucindezela kwe-zigzag okubizwa ngokuthi amazinga okushisa aphezulu abizwa ngokuthi amazinga okushisa aphezulu abizwa ngokuthi amazinga okushisa aphezulu abizwa ngokuthi ama-craecraries amnyama noma ama-emnyama amnyama} Ukuqhekeka okwenziwe esifundeni esiphansi sokushisa kubizwa ngokuthi ukuqhekeka kwezinga lokushisa okuphansi, ngokuvamile kufunyana nokungena okusanhlamvu, kanye nokuqhekeka okuqhekeka kune-luster yensimbi .
