Precious metal based amorphous alloys

   
   

The present invention is a precious metal-based amorphous alloy having a Pt--Cu--P based structure including in atomic %: 50.ltoreq.Pt.ltoreq.75%, 5.ltoreq.Cu.ltoreq.35%, and 15.ltoreq.P.ltoreq.25% and is a precious metal-based amorphous alloy having a Pt--Pd--Cu--P based structure including in atomic %: 5.ltoreq.Pt.ltoreq.70%, 5.ltoreq.Pd.ltoreq.50%, 5.ltoreq.Cu.ltoreq.50%, and 5.ltoreq.P.ltoreq.30%. Preferably, cooling rates for manufacturing the alloys having these compositions are 10.sup.-1 to 10.sup.2.degree. C./sec. for the Pt--Cu--P based structure and 10.sup.1 to 10.sup.2.degree. C./sec. for the Pt--Pd--Cu--P based structure.

Присытствыющим вымыслом будет очень металл-osnovanny1 аморфический сплав имея пинту -- cu -- структура основанная п вклюая в атомные %: 50.ltoreq.Pt.ltoreq.75%, 5.ltoreq.Cu.ltoreq.35%, и 15.ltoreq.P.ltoreq.25% и будет очень металл-osnovanny1 аморфический сплав имея пинту -- палладиум -- cu -- п основанная структура вклюая в атомные %: 5.ltoreq.Pt.ltoreq.70%, 5.ltoreq.Pd.ltoreq.50%, 5.ltoreq.Cu.ltoreq.50%, и 5.ltoreq.P.ltoreq.30%. Предпочтительн, охлаждать классифицирует для изготовлять сплавы имея эти составы будет 10.sup.-1 к 10.sup.2.degree. C./sec. для пинты -- cu -- п основало структуру и 10.sup.1 к 10.sup.2.degree.
