Titanium　alloy　is　the　highest　specific　strength　metal　material,　widely　used　in　aerospace　field.　With　the　progress　of　material　technology,　the　research　and　development　of　high　strength　titanium　alloy　are　gradually　deepened.　In　this　paper,　the　development　status　and　main　strengthening　methods　of　high　strength　β　titanium　alloy　at　home　and　abroad　were　reviewed.　The　typical　high　strength　titanium　β　alloys　such　as　Ti-13-11-3,　Ti-1023,　Ti-5553　and　Ti-55531　were　mainly　introduced.　The　design　ideas　of　high　strength　β-titanium　alloy　were　sorted　out,　the　bottlenecks　that　restrict　the　development　of　high　strength　β-titanium　alloy　to　better　performance　were　pointed　out,　and　the　possible　solutions　were　put　forward.　The　strengthening　methods　of　high　strength　β　titanium　alloy,　such　as　solution　strengthening,　precipitation　strengthening,　work　hardening,　fine　grain　strengthening　and　additive　technology,　were　summarized　to　provide　guidance　for　further　improving　the　strength　of　high　strength　β　titanium　alloy　and　optimizing　the　comprehensive　properties　of　high　strength　β　titanium　alloy.　©　2024　Beijing　University　of　Technology.　All　rights　reserved.
