Summary: | The invention discloses a heat treatment process for optimizing comprehensive mechanical properties of a laser additive manufacturing high-temperature titanium alloy, which is used for carrying out triple heat treatment on the laser additive manufacturing high-temperature titanium alloy to obtain the laser additive manufacturing titanium alloy with good room-temperature strong plasticity matching and better high-temperature stretching and durability. According to the method, a fine needle-shaped lamellar structure of the laser additive manufacturing titanium alloy is evolved into a composite structure with a primary thick lamellar layer alpha, a fine secondary lamellar layer alpha and a residual beta phase by adopting triple heat treatment, so that the laser additive manufacturing titanium alloy breaks through the limitation that the strength and the plasticity are difficult to match well; according to the present invention, good room temperature strength and plasticity matching and good high temperature stre |
