Research on Large-sized Bars of Ti-1023 Alloy
The tonnage of titanium alloy ingot was smelted by utilizing autonomic technology,the chemical composition of the ingot meets the technical requirements,and the microstructure of the ingot is homogeneous and equiaxed grain.The ingot was forged by adopting "high-low-high-low" process route in multiple heating,and finally,forged into 准360 mm bar.The results shows that the microstructure,the macrostructure and the mechanical properties at room temperature all meet the technical requirements.
