Influence of elevated temperature holding time on microstructure and properties in heat affected zone of fine grained titanium alloy

Fine structure in coarse grain region of fine grained titanium alloy

The effect of the initial microstructures on the formation of ultrafine grained titanium alloy by compressive deformation was studied.

The dry and high-speed cutting experiments are carried out to study the cutting performance of turning the Fe-based PM parts by using the fine grain cemented carbide inserts.
