Interfacial reactions in magnesium-base composite materials reinforced with boron and steel fibers

1. A study was made, by the methods of metallographic examination, electron probe microanalysis, and x-ray phase analysis, to ascertain whether the components of Mg—B and Mg—steel composites produced by plasma spraying of the matrix material on fibers and subsequent densification by hot pressing (diffusion welding) react with each other. 2. It was established that, within the limits of resolving power of the techniques employed, no fiber/matrix interface reactions occur in such Mg—B and Mg—steel composites under the densification and annealing conditions investigated.
