Abstract
WITH RAPID SOLIDIFICATION, IT IS POSSIBLE TO PRODUCE ALUMINUM-IRON ALLOYS WHICH HAVE USABLE STRENGTHS AT 500 DEG F. HOWEVER, AT 650 DEG F, THESE ALLOYS UNDERGO REARRANGEMENT AND LOSE STRENGTH. THIS PROPOSAL SUGGESTS THE UNIQUE COMBINATION OF OXIDE DISPERSION STRENGTHENING WITH COLLOIDAL OXIDES WHICH ARE WETTED BY THE MOLTEN ALUMINUMIRON ALLOYS. BECAUSE THE OXIDES ARE METALLOPHILIC, IT WILL BE POSSIBLE TO MELT THE ALLOYS WHILE STILL MAINTAINING THE OXIDE DISPERSION, AND THEREAFTER RAPID SOLIDIFY. WITH THIS COMBINATION STRENGTH WILL BE PRESERVED TO MUCH HIGHER TEMPERATURES AND PERHAPS THE RS MICROSTRUCTURE WILL ALSO BE PRESERVED.
