Research progress and application status of titanium and titanium alloy stamping

Nov 09, 2018

Titanium is one of the most widely distributed elements in the earth's crust, accounting for about 0.6% of the total weight of the earth's crust. It ranks fourth in the metal after aluminum, iron and magnesium. Titanium and titanium alloys have the following excellent characteristics: high specific strength, comparable to general high-strength structural steels and high-temperature alloys, but their density is only about 57% of steel; corrosion resistance is strong, titanium is a chemically active metal At room temperature, the metal surface is easy to form a passivation film composed of oxide or nitride with high stability and strong adhesion; the low temperature performance is good, and under high temperature and ultra-low temperature conditions, it can maintain high strength while still having Adequate low temperature toughness and ductility; good biocompatibility, low modulus of elasticity, no magnetism, no toxicity, etc. Titanium and titanium alloys have many of the above characteristics, and stamped and formed parts are widely used in aerospace, marine and biomedical fields. This paper reviews the research progress and application status of titanium and titanium alloy stamping, in order to provide reference for the research and application of titanium and titanium alloy stamping process
