Abstract

Свободные от окиси металл, сплав или интерметаллическое соединение, образованные путем покрытия окисьзамещающим металлом порошка, состоящего по крайней мере из одного вещества, выбранного из группы, состоящей из элементарного металла, сплава или интерметаллического соединения. Свободный от окиси состав может быть прессован без добавления жидкого спекающего вещества и при температурах ниже температуры плавления состава под давлением, достаточным для образования уплотненного интерметаллического сплава.
