Itekhnoloji ephambili yeBeryllium Copper (Unyango lobushushu)
Unyango olushushu yeyona nkqubo ibaluleke kakhulu kule nkqubo ye-alloy. Ngelixa zonke ii-alloys zobhedu zilukhuni ngokusebenza okubandayo, i-beryllium yobhedu iyingqayizivele ekubeni lukhuni ngonyango olulula olulula lobushushu obuphantsi. Ibandakanya amanyathelo amabini asisiseko. Eyokuqala ibizwa ngokuba kukunqanda isisombululo kwaye okwesibini, ukuna kwemvula okanye ukuqina kweminyaka.
Isisombululo seAnealing
Kwi-alloy eqhelekileyo CuBe1.9 (1.8- 2%) i-alloy ifudunyezwa phakathi kwe-720 ° C kunye ne-860 ° C. Ngeli xesha i-beryllium equlethwe ngokuyimfuneko "ichithwe" kwi-matrix yobhedu (isigaba se-alpha). Ngokucinywa ngokukhawuleza kwiqondo lokushisa legumbi esi sakhiwo sesisombululo esiqinileyo sigcinwa. Izinto ezikweli nqanaba zithambe kakhulu kwaye zithambile kwaye zinokubanda ngokukhawuleza ngokuzoba, ukwenza ukuqengqeleka, okanye isihloko esibandayo. Isisombululo sokusebenza kwe-annealing yinxalenye yenkqubo yokusila kwaye ayiqhelekanga ukusetyenziswa ngumthengi. Ubushushu, ixesha kwiqondo lobushushu, izinga lokucima, ubungakanani beenkozo, kunye nobulukhuni zonke ziiparameters ezibaluleke kakhulu kwaye zilawulwa ngokuqinileyo yi-TANKII.
Ubudala Ukuqina
Ukuqina kweminyaka kukhulisa kakhulu amandla ezinto. Le ntshukumo iqhele ukwenziwa kumaqondo obushushu aphakathi kwe-260°C kunye ne-540°C ngokuxhomekeke kwingxubevange kunye neempawu ezifunekayo. Lo mjikelo ubangela ukuba i-beryllium enyibilikileyo iqhube njenge-beryllium ecebileyo (i-gamma) isigaba kwi-matrix nakwimida yengqolowa. Kukubunjwa kwale precipitate ebangela ukwanda okukhulu kwamandla ezinto eziphathekayo. Umgangatho weempawu zomatshini ezifunyenweyo zichongwa ngubushushu kunye nexesha kwiqondo lokushisa. Kufuneka kuqatshelwe ukuba i-beryllium yobhedu ayinayo iimpawu zokuguga kweqondo lokushisa.
