Karolo e kholo ea Tungsten Heavy Alloy (WNIFE).
Tlhaloso
Re barekisi ba khethehileng ba ho etsa likarolo tsa alloy tse boima tsa tungsten.Re sebelisa lisebelisoa tse tala tsa tungsten heavy alloy e nang le bohloeki bo phahameng ho hlahisa likarolo tsa tsona.Re-crystallization ea mocheso o phahameng ke e 'ngoe ea likarolo tsa bohlokoa bakeng sa likarolo tsa alloy tse boima tsa tungsten.Ho feta moo, e na le polasetiki e phahameng le khanyetso e ntle ea abrasive.Mocheso oa eona oa re-crystallization o feta 1500 ℃.Likarolo tsa alloy tse boima tsa tungsten li lumellana le maemo a ASTM B777.
Thepa
Boima ba likarolo tsa motsoako o boima oa tungsten ke 16.7g/cm3 ho isa ho 18.8g/cm3.Ntle le moo, likarolo tsa alloy tse boima tsa tungsten li na le litšobotsi tsa mocheso o phahameng le ho hanyetsa kutu.Likarolo tsa alloy tse boima tsa Tungsten li na le khanyetso e ntle ea ho ts'oha le polasetiki ea mochini.Likarolo tsa alloy tse boima tsa Tungsten li na le coefficient e tlase ea katoloso ea mocheso, bokhoni ba ho monya mahlaseli a matla a phahameng.
