Abstract

Vacuum brazing under 1-g and microgravity (carried out on TEXUS II in preparation of an experiment for FSLP) conditions revealed the effect of various parameters (e.g. thermal history, hydrostatic pressure, buoyancy forces) on the microstructure of the joint and the gap filling phenomena.

The following results will be presented:

(a) Design of brazing specimens

(b) Variations of microstructure depending on gap width, gravity, and thermal history

(c) Flow patterns of molten braze as revealed by radioactive tracer experiments

(d) Evaluation of Plateau-type simulation experiments
