Titanium alloy isothermal forging process specification

1 Scope

This standard specifies the process specifications for titanium alloy isothermal forgings (hereinafter referred to as "forgings"), including general rules, requirements, and process. This standard applies to the formulation of titanium alloy isothermal forging process.

2 Normative references

The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article Pieces. For undated references, the latest version (including all amendments) applies to this document.

3 Terms and definitions

The following terms and definitions defined in GB/T 8541 apply to this document. 3.1 Titanium alloy α β forging α β forgingoftitanium-aloy Titanium alloys are forged after heating at 20°C~50°C below the β transformation temperature (Tβ), that is, conventional two-phase zone forging to obtain a dual-state structure or Isometric organization. 3.2 Titanium alloy near β forging near β forging of titanium-aloy Titanium alloys are forged after heating at 10°C~20°C below the beta transition temperature (Tβ), and the primary alpha phase content is usually 15%~ 30% dual-state organization. 3.3 Titanium alloy quasi β forging of titanium-aloy The titanium alloy is preheated at 10℃ below the β transformation temperature (Tβ) and then heated with the furnace to 30℃ above the β transformation temperature (Tβ), and then heated for a short time. Forging is performed to obtain a net basket organization or two-state organization with a primary α-phase content of not more than 15%. 3.4 Titanium alloy β forging β forgingoftitanium-aloy Titanium alloys are forged after heating in the β zone at 10°C or higher above the β transformation temperature (Tβ), and the primary α phase content is usually obtained Not more than 15% net basket organization or sheet organization. 3.5 Isothermal forging of titanium-aloy During the titanium alloy die forging process, the blank temperature is kept constant forging method. Under normal circumstances, the mold temperature is the temperature of the forged workpiece 95%~100% of the pressure, the pressure holding time is usually 60s~900s. ......
