Nanostructured in-situ TióAl4V alloy powder was obtained by use of mechanical alloying. A stoichiometric mixture of Ti, Al and V powders was subjected to intense mechanical treatment in a planetary ball mill. Structural changes of the milled powders were investigated by XRD. The Ti(Al,V) solid solution formed after 10 h milling. Prolongation of the milling process up to 20 h lead to a structure consisting of the B-Tiphase in the a-Ti(Al) matrix. The nanostructured TióAl4V alloy had a grain size of about 20 nm after 20 h milling.
