Preparation of amorphous ferromagnetic materials through containerless solidification

The work reported herein consists of: (1) the ground based experiments; (2) the analysis of the ground based specimens; (3) the flight experiment; (4) failure to melt analysis; and (5) recommendations and conclusions. The ground based experimental work yielded new results in terms of understanding the viscoelastic properties of ferromagnetic metallic glasses and the variation of viscosity through the glass transition temperature from metallic glass to crystalline solid. This last result was of importance in predicting what glass can be produced at lower quench rates.
