Окисна  фаза (, MgO) 0,5-4,0 Сплав получают путем плавки сплава заданного химического состава и последующим распылением порошков. В том случае, когда сплав предназначаетс  дл  работы при 150- 350°С, порошки дополнительно размалывают в шаровых мельницах дл  введени  окисной фазы. Затем порошки подвергают гор чему брикетированию при 450°С и давлении 30-70 КГ/ММ2.Oxide phase (, MgO) 0.5-4.0 The alloy is produced by melting an alloy of a given chemical composition and then spraying the powders. In the case where the alloy is intended to operate at 150-350 ° C, the powders are further ground in ball mills to introduce the oxide phase. Then, the powders are subjected to hot briquetting at 450 ° C and a pressure of 30-70 KG / MM2.

Прессование полуфабрикатов (прутков, труб) и последующее изготовление из лрутковых заготовок осуществл ют при 400°С.The pressing of semi-finished products (rods, pipes) and the subsequent production of billet blanks is carried out at 400 ° C.

Состав и свойства испытуемых сплавов приведены в таблице.The composition and properties of the tested alloys are given in the table.

Введение хрома в состав спеченного коррозиоЕностойкого сплава позвол ет значительно повысить прочность и предел текучести за счет образовани  пересыщенного твердого раствора, а также образовани  мелкодисперсных интерметаллических :соединений Ali2 Mg2Cr и СгАЬ.The introduction of chromium into the composition of a sintered corrosion-resistant alloy allows a significant increase in strength and yield strength due to the formation of a supersaturated solid solution, as well as the formation of fine intermetallic compounds: Ali2 Mg2Cr and CgBA.

Введение бора позвол ет добитьс  допол.нительного повышени  пределов прочности и текучести за счет образовани  мелкодисперсных Соединений А1В2, AlBi2. The introduction of boron makes it possible to achieve an additional increase in the strength and yield strength due to the formation of finely dispersed Compounds A1B2, AlBi2.
