Iindlela zokushushumbisa kunye nokuCoca kweMetri
Uphi unyango lomlilo?
Ukunyanga kwefuthe yinkqubo yokufudumala nokupholisa izitye ukutshintsha i-microstructure yabo kunye nokuvelisa iimpawu zenyama kunye nezobunzima ezenza izinyithi zibe zifunwa.
Iqondo lokushisa litshisa kwaye izinga lokupholisa emva kokuba unyango lushisa lunokutshintsha kakhulu iipropati zetsimbi.
Izizathu eziqhelekileyo izinyithi eziphantsi kokunyanga ukushisa kukuphucula amandla abo, ubunzima, ubunzima, i-ductility kunye nokuxhatshazwa kwe-corrosion. Fumana ingcamango engcono yenkqubo kunye nemimiselo yonyango oluqhelekileyo lonyango olulandelayo.
Ukuqonda ukuHlulela
I-Annealing yindlela yokutshatyalaliswa kwezoshisa ezenza isinyithi sisondele kwimeko yayo yokulingana. I-Annealing ithambisa isinyithi ukwenzela ukuba isebenze ngakumbi kwaye inikezele i- ductility enkulu. Kule nqubo, isinyithi siyashushulwa ngaphezu kweqondo lokushisa eliphambili lokutshintsha i-microstructure yayo. Emva koko, isinyithi ipholile.
Yintoni Ukucima Umlilo?
Ixabiso elingaphantsi kunelokuqhawula, ukucima indlela yonyango yokutshatyalaliswa kweso sinyithi ngokukhawuleza ibuyisela isinyithi kwindawo yokushisa kwinqanaba emva kokuba lichazwe ngaphezu kweqondo lokushisa eliphezulu. Inkqubo yokucima iyeka inkqubo yokupholisa ekutshintsheni i-microstructure yensimbi.
Ukucima, okunokwenziwa ngamanzi, ioli kunye neminye imidiya, inzima insimbi kwiqondo lokushisa elifanayo ekuzaleni ngokupheleleyo.
Inkqubo yokuLungisa ukuNciphisa
Ukuqina kancinci kukwaziwa nangokuthi kunzima ukukhula. Yinkqubo yonyango yokushisa eyenza ukulingana kwisakhiwo sesantya sesinyithi.
Le nkqubo yenza izinto ziqine.
Inkqubo ibandakanya ukufudumeza isicombululo sonyango kumaqondo aphezulu emva kwenkqubo yokupholisa ngokukhawuleza. Ukuqina kancinci ngokuqhelekileyo kuqhutyelwa kwimoya yesimo esiphezulu kumaqondo okushisa ukusuka kwi-900 ukuya ku-1150 ° F. Ingathatha naliphi ukusuka kwiyure ukuya kwiiyure ezine ukuphumeza le nkqubo. Ubude bexesha buxhomekeke kubukhulu bezinyithi kunye nezinto ezifanayo.
Kutheni Iimpawu Zigxilile?
Ngokuqhelekileyo isetyenziswe kwintsimbi yokucwangcisa namhlanje, ukukhupha imilutha yonyango esetyenziselwa ukuphucula ubunzima kunye nobunzima kwintsimbi kunye nokunciphisa ubuqili. Inkqubo yokubanda yenza i-ductile kunye nesakhiwo esomeleleyo. Injongo yokubamba ingqondo kukufezekisa intlangano engcono yepropati yezitshini.
Yintoni Ukuxinwa
Ukuxinwa kwengcinezelo yinkqubo yokunyusa ubushushu eyanciphisa uxinzelelo kwizinyithi emva kokucinywa, ukukhishwa, okuqhelekileyo, njl. Emva kwalolu hlobo, isitye sitshatyelwe ngokukhawuleza.
Izinzuzo zeZonyango ze-Cryogenic
Xa inxalenye yesinyithi iphathwa ngonyango , ipholile ngokukhawuleza nge-nitrogen. Inkqubo epholileyo yokupholisa inceda ukunqanda uxinzelelo lobungqingili bensimbi.
Emva koko, inxalenye yensimbi igcinwa kwiqondo lokushisa elingama-90 ° C malunga nomhla.
Xa kuthe kwandula ukufudumala kweshushu, inxalenye yensimbi iyancipha izinga lokushisa ukuya kwi-+149 ° C. Ukufudumala kweentlungu kunceda ukunciphisa ubuninzi bokubakho okungabangela ukuba i-martensite ifake ngexesha lonyango lwe-cryogenic.
