Method for promoting phase change strengthening and toughening of two-phase titanium alloy strip by using pulse current and strip
The invention discloses a method for promoting phase change strengthening and toughening of a two-phase titanium alloy strip by using pulse current. The method comprises the following steps: tensioning a TC4 titanium alloy strip through a decoiling device, a winding device, a roller and a support roller of a rolling mill, so that the strip is in tightly elastic contact with the roller; driving the strip to transmit at the speed of 150-800mm / min through friction force by virtue of the roller; inputting the pulse current into a power-up area section of the strip through the roller, the support roller and the like, wherein the pulse current generates a joule heating effect and a non-thermal effect in the power-up area section of the strip within 12-18 seconds, so that the internal microstructure of the strip turns into a two-phase long-axis structure or a two-phase dual-state structure from an original quasi-single phase thick equiaxed structure; and then cooling by natural air at room temperature. Through adjustment of parameters of the pulse current, the TC4 strip with the two-phase long-axis structure and the two-phase dual-state structure can be quickly obtained, thus the ductility is increased; the treatment temperature is far lower than 960 DEG C of a traditional thermal treatment process; the processing process of the titanium alloy strip can be finished without a short period of time at relatively low temperature without an oxidation phenomenon; and therefore, the method is energy-saving, environmentally friendly, safe and efficient.
