- Изобретение относитс к металлургии , в частности к термической обработке сурьм нистых бронз оно может быть использовано в машинострсУении.- The invention relates to metallurgy, in particular to the heat treatment of antimony bronze, it can be used in engineering.
Известен способ термической обработки бронз путем нагрева их до 600650 С I.l1 . Однако этот способ не обеспечивает получени высоких механических свойств медносурьм нистых бронз, легированных никелем и (или) фосфором и дл обработки их в литом состо нии ранее не примен лс .The known method of heat treatment of bronze by heating them to 600,650 From I.l1. However, this method does not provide for obtaining high mechanical properties of copper-serum bronze alloyed with nickel and (or) phosphorus and has not been previously used for treating them in the molten state.
Целью изобретени вл етс повьшение механических свойств медносурьм нистых бронз, легированных никелем и (или) фосфором. Это достигаетс тем,. что медносурьм нистую бронзу, легированную никелем и (или) фосфором, нагревают до 610-630 С, выдерживают при указанной температуре и после охлаждени повторно отжигают при 250-300 С в течение 3-5 ч.The aim of the invention is to increase the mechanical properties of copper-serum bronze alloyed with nickel and / or phosphorus. This is achieved by that copper or bronze doped with nickel and (or) phosphorus is heated to 610-630 ° C, maintained at the specified temperature and, after cooling, re-annealed at 250-300 ° C for 3-5 hours.
Положительный эффект при такой обработке достигаетс в результате боле полного распада твердого раствора.A positive effect on such treatment is achieved as a result of a more complete decomposition of the solid solution.

по предложенному способу подвергают термической обработке бронзу БрСуН7-2. Сплав нагревают до 610620С , выдерживают при этой температуре 3-4 ч и после охлаждени на воздухе повторно отжигают при в течение 2-4 чunder the proposed method is subjected to heat treatment of bronze BrSuN7-2. The alloy is heated to 610620С, kept at this temperature for 3-4 hours and after cooling in air, is re-annealed for 2-4 hours
Свойствасплава в исходном состо нии и после-предложенной термической обработки приведены в таблице.The properties of the alloy in the initial state and the post-proposed heat treatment are given in the table.
Мелносурьм нистые бронзы, обработанные по предложенному способу позвол ют замен ть дефицитные олов нистые бронзы.The fine bronze treated according to the proposed method allows the replacement of deficient tin bronze.
