Beschreibung:
<jats:p>The as-cast and hot worked microstructures of the newly developed β-solidifying
ingot-metallurgy Ti-45Al-X (Nb,Mo,B) alloy and its superplastic properties in the hot worked
condition have been studied. The obtained experimental findings were used for research of
superplastic forming and diffusion bonding of sheet products, which were cut out of hot worked
preform by spark cutting. It was shown that superplastic forming might be successfully applied to the
obtained fine-grained sheet materials. Relatively low bonding temperatures and pressures were found
to be sufficient to achieve sound joints in the sheet material.</jats:p>
