Relationship between Intragranular α Phase Width and Microhardness of TC18 Titanium Alloy

摘要：

　　Four typical microstructures of TC18 titanium alloy (Widmannstatten structure,Fine basketweave structure,Bi-model structure,Coarse basketweave structure) were investigated,including the changes of intragranular α phase width and the relationship between intragranular α phase width and microhardness.The results show that the intragranular α phase width of the four typical microstructures varies greatly in accordance with the order from smallest to largest: Widmannstatten structure < Fine basketweave structure <Bi-model structure < Coarse basketweave structure.The microhardness of the TC18 titanium alloy reduces with the increase of intragranular α phase width.
