IN CHAMBER PRODUCTION OF TITANIUM ALLOY FOIL BY THE RAPID SOLIDIFICATION TECHNIQUE CALLED MELT OVERFLOW

THE PRODUCTION OF A TITANITUM ALLOY FOIL FOR USE AS A BASE FOR METAL MATRIX COMPOSITES SUCH AS SILICON CARBIDE - TITANIUM IS TO BE INVESTIGATED. THE ALLOY TI-6AL-4V WILL BE CAST IN A VACUUM CHAMBER USING THE MELT OVERFLOW PROCESS. MELT OVERFLOW IS A VARIATION OF THE RAPID SOLIDIFICATION TECHNIQUE MELT SPIN AND IS CAPABLE OF ACHIEVING QUENCHING RATES OF UP TO 10(5) K/SEC. THE ADAPTABILITY OF THE MELT OVERFLOW PROCESS TO VACUUM CHAMBER CONDITION AND THE PARAMETERS EFFECTING THE CONTROL OF THE PROCESS IN CHAMBER WILL BE RESEARCHED. SAMPLES OF TITANIUM ALLOY FOILS WILL BE PRODUCED AND EVALUATED BY MICROSTRUCTURAL ANALYSIS. AN ATTEMPT WILL BE MADE TO RELATE PROCESS PARAMETERS TO THE CONDITIO OF THE FINAL PRODUCT.
