Performance characteristics of grade 7 titanium alloy
Excellent corrosion resistance, improved crevice corrosion resistance
Good high temperature performance and superior strength
Lightweight and biocompatible
Good welding performance, good processing, forming and welding properties
Heat Treatment of Grade 7 Titanium Alloys
Heat treatment methods for Grade 7 titanium alloys include stress relief annealing and solution treatment.
1. Stress relief annealing treatment can eliminate the internal stress generated during the welding process and avoid cracking during hydroforming. Annealing can also reduce the strength of the material and improve its plasticity. In order to reduce the contamination of the surface of grade 7 materials by various gases during the heat treatment process, anti-oxidation paint can be painted on the surface of the blank
2. Solution treatment is to heat the material to a high temperature, maintain this temperature for a certain period of time, and then cool it quickly. This process can dissolve the alloy elements in the material into the matrix, improving the hardness and strength of the material.
