Structure and properties of hot-rolled strips obtained from titanium chips without chip remelting

Introduction of hydrogen technology provided hot-rolling fabrication of thin strips from chips of VT1-0 titanium alloy without chip remelting. It is established that the plasticity of strips made from this alloy largely depends on the presence of excess dispersed particles in the structure. It is assumed that they are the sparingly soluble oxides formed during the destruction in the course of pressure treatment of the oxide film retained on the chip surface. After homogenization, which can be combined with vacuum annealing for hydrogen removal, the structure and mechanical properties of the strips obtained by hydrogen technology correspond to the characteristics of semifinished products fabricated by ingot technology.
