I-malleability yensimbi ingalinganiswa yindlela ingcinezelo (ukunyanzela uxinzelelo) inokumelana ngayo ngaphandle kokuphula. Ukwahlukahlukana kwintlupheko phakathi kweensimbi ezahlukeneyo kubangelwa ukuhluka kwii-crystal zakhiwo.
Ukunyanzela uxinzelelo kwee-atom ukugqithana kwisithuba esitsha ngaphandle kokuphulaphula uxhamlwano lwe-metallic. Xa ubuninzi bexinzelelo bebekwe kwisinyithi esingenakulinganiswa, ii-athomu ziyaqhelana, zihlala ngokusisigxina kwindawo yazo entsha.
Imizekelo yezinyithi ezingenakwenzekayo:
Imizekelo yeemveliso ezibonisa ukungabikho komzimba ziquka iqabunga legolide, i-lithium foil, kunye ne-indium shot.
Ukungaphumeleli kunye nobunzima
Isakhiwo se-crystal sesinyithi esinamandla, ezifana ne-antimony kunye ne- bismuth , yenza kube nzima ukucima ii-athomu kwizikhundla ezintsha ngaphandle kokuphula. Oku kungenxa yokuba imigqa yee-atom kwisitrato ayinamathelwano. Ngamanye amazwi, kukho imida engqolowa kunye nezinyithi zivame ukuqhekeka kwimida yengqolowa. Imida yezolimo yimihlaba apho i-athomu ingabonakali ngokuqinileyo. Ngako oko, imida engakumbi yintsimbi inesibindi, inzima kakhulu, kwaye ke ngoko, iyakuthi ingabonakali.
Ukungabikho kokungahambi kakuhle
Nangona i-malleability yipropati yokuqhaqhaqhaqeka kwesinyithi phantsi koxinzelelo, i- ductility yipropati yensimbi evumela ukuba itwebe ngaphandle kwemonakalo.
I-Copper ngumzekelo wesinyithi enesibini esilungileyo (singatyulwa kwiifowuni) kunye nokuhleleka kwezinto ezinokutsha (kungaphinda kuhanjiswe kumashidi).
Ngelixa ezininzi izitye ezingenakunyakaleka nazo ziyi-ductile, ezi zimbini ziyakodwa. Ikhokelo kunye ne-tin, umzekelo, ziyakwazi ukutshatyalaliswa kunye ne-ductile xa zibandayo kodwa zikhula ngokugqithiseleyo xa amazinga okushisa aqala ukuphakama kwiindawo zabo ezincibilikayo.
Uninzi lwezinyithi, nangona kunjalo, lube lukhulu xa luvutha. Oku kungenxa yempembelelo yeqondo lokushisa elinamafutha e-crystal ngaphakathi kwinyithi.
Ukulawula i-Crystal Grains Through Temperature
Ukushisa kunempembelelo ngqo kwiimilo yee-athomu, kwaye kwiindawo ezininzi zokushisa kwezinyithi ziphumo kuma-athomu anelungiselelo oluqhelekileyo. Oku kunciphisa inani leemingcipheko zengqolowa, ngaloo ndlela, okwenza isinyithi esicacileyo okanye ngaphezulu singenakunyuswa.
Umzekelo wefuthe lokushisa kwizinyithi unokubonwa nge- zinc , enesinyithi esiphantsi kwe-300 ° F (149 ° C). Nangona kunjalo xa kushushu phezu kwelo bushushu, i-zinc ingaba yinto enokuthi ingabonakaliyo ingafakwa kwiimakhishithi.
Ngokuphambene nomphumo wonyango lokushisa , ukusebenza okubanda (inkqubo equka ukugqithisa, ukudweba, okanye ukunyusa ukukhutshwa kweplastiki kwintsimbi ebanda) kudala kubangele iinqununu ezincinci, okwenza isinyithi sibe nzima.
Ngaphandle kweqondo lokushisa, ukulungiswa yindlela enye eqhelekileyo yokulawula ubuninzi bezityalo ukuze wenze izinyithi zibe nzima.
I-Brass , i- alloy yobhedu kunye ne-zinc, ilukhuni kunezo zombini izitya ngenxa yokuba isityalo sawo sinqabile ukunyanzeliswa kwengxaki yokuzama ukunyanzela imigqa yee-athi ukuba ingene kwiindawo eziza kutshintsha.
