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. Iqondo lobushushu, ixesha kwiqondo lobushushu, izinga lokucima, ubungakanani bengqolowa, kunye nobulukhuni zonke ziiparameters ezibaluleke kakhulu kwaye zilawulwa ngokuqinileyo yiTANKII.
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.
