Usayizi wokusanhlamvu ubhekisa kusayizi wokusanhlamvu ngaphakathi kwe-crystal yosayizi wokusanhlamvu. Usayizi wokusanhlamvu ungavezwa yindawo ephakathi noma ububanzi obumaphakathi okusanhlamvu. Usayizi wokusanhlamvu uvezwa ibanga elingusayizi lokusanhlamvu ekukhiqizweni kwezimboni. Usayizi ojwayelekile wokusanhlamvu ukhula, okungukuthi, ongcono kakhulu. Ngokusho kwesihloko esilandelayo, ngithemba ukuthi kungakusiza uqonde ubukhulu bokusanhlamvu kokwenziwa. Ngikholwa ukuthi ujwayelene nobukhulu bokusanhlamvu kosongo, khona-ke akufanele sazi okuningi ngosayizi wokusanhlamvu wokwenziwa kokusanhlamvu.
Ukuguqulwa kwepulasitiki kokukhokhiswa kwephula amakristalu asemqoka ama-dendritic aphambili futhi kunomphumela obalulekile wokucwengwa okusanhlamvu. Ngakolunye uhlangothi, kunenqubo yokuphindaphinda lapho kuguqulwa ngepulasitiki ekushiseni okuphezulu. Ngesikhathi sokushisa okushisa kakhulu kwepulasitiki, usayizi wokusanhlamvu weukuthethelelwaNgemuva kokuphinda usebenze kabusha kunqunywa ngokushisa, degreenational degree degree kanye nesivinini. Ngakho-ke, usayizi wokusanhlamvu weukuthethelelwaetholakala ngezinqubo ezahlukene zokukhokhiswa ihlukile.

Izakhiwo eziphambili zemishini zokuthethelelwa ezinama-raines ama-coarse ukuthi ipulasitiki yazo nokuqina kuphansi kakhulu kunaleyo enezimbango ezinhle. Ukucwilisa okusanhlamvu ngokwelashwa kokushisa akuyona nje kuphela yabasebenzi - kugxilile futhi kubize, kepha futhi kube nzima futhi kungenakwenzeka ngamanye ama-alloy athile. Ngakho-ke, abanengqondoukuthethelelaInqubo yamabanga athile wensimbi kumele isebenze ngokusho komdwebo wobumbano bokusebenza okushisayo.
Ukushisa okuphezulu kwamazinga okushisa, kukhulu usayizi wokusanhlamvu wokwenziwa ngemuva kokuphinda usebenze kabusha. Ngakho-ke, amazinga okushisa okugcina kufanele ancishiswe ngangokunokwenzeka ukuze aqinisekise ukucwengeka okusanhlamvu ngaphansi kwesimo sokuthi lokhu kuzokwenza kungakhiqizi okushisa okuphansi. Kodwa-ke, kunzima kakhulu ukuthethelelwa okukhulu ukuqinisekisa izinga lokushisa elifanayo lokugcina eliphansi kuzo zonke izingxenye zokuvumelana okufanayo. Lokhu kungenziwa kuphela ngesipiliyoni nekhono labasebenzi be-master.
KokuthileukuthethelelaUkushisa, kukhona uhla olubucayi degree degree degree. Lapho i-defformation degree ingaphakathi kwaleli banga, okusanhlamvu okuphindaphindeke kwangempela kwe-Fimibii-coarse ngokulinganayo. Ngakho-ke, izinga lokukhubazeka ngesikhathi esifaneleyo, ikakhulukazi emlilweni wokugcina, kufanele ligwenywe ngangokunokwenzeka ngaphakathi kwezinga elibucayi lokukhubazeka.
Okusanhlamvu akuwona umfaniswano kubhekisele kwezinye izingxenye zokusanhlamvu okusanhlamvu ikakhulukazi, ezinye izingxenye zincane. Isizathu esiyinhloko sosayizi wokusanhlamvu ongalingani ukuthi ukuguquguquka okungalingani kwe-billet kwenza iziqu zokuhlukaniswa okusanhlamvu kwezehlakalo ze-superlloy, noma umsebenzi wendawo osanhlamvu wasendaweni lapho usayizi wokusanhlamvu lapho ushisa. Izinsimbi ezingamelana ukushisa kanye nama-superlosi azwela kakhulu ku-inhomogeneity. Usayizi ongalingani nokusanhlamvu uzokwehlisa ukuqina nokungasebenzi kahle kokukholelwa.
Le ndatshana isho ngokuyinhloko ngosayizi wokusanhlamvu. Ngiyethemba kuzosiza kuwe.
