Example Embodiment

[0035] Specific implementation mode 1: The method for connecting and forming a semi-solid material in this embodiment is carried out in the following steps:

[0036] 1. Two or more pre-connected materials are respectively prepared into semi-solid blanks or semi-solid slurry, wherein the type of pre-connected materials prepared into semi-solid blanks is greater than or equal to that of pre-connected materials prepared into semi-solid slurry species;

[0037] 2. If all the pre-connected materials are prepared into semi-solid blanks in step 1, the semi-solid blanks of the pre-connected materials prepared in step 1 are heated to a predetermined temperature range, and then the heated semi-solid blanks are placed in the mold cavity Or place it under a roll for thixoforming. When the die forging or rolling is completed, the connected and formed part is taken out to complete the semi-solid connection and forming integration process of the required part;

[0038] If both the semi-solid blank...

Example Embodiment

[0042] Specific embodiment two: this embodiment is different from specific embodiment one in that the pre-connection material in step one is a metal material or a metal matrix composite material. Others are the same as the first embodiment.

Example Embodiment

[0043] Specific embodiment three: This embodiment is different from the specific embodiment two in that the metal material is a high-temperature alloy. Others are the same as the second embodiment.

[0044] The metal materials described in this embodiment are not limited to high-temperature alloys, and any metal material with semi-solid structure characteristics can implement the present invention.

Abstract

A method for connecting semi-solid materials into a whole relates to the technical field of material connection and formation and solves the problem that an existing mechanical connection, glue joint and conventional fusion welding method is difficult to obtain good joint comprehensive performance. The method for connecting the semi-solid materials into the whole includes that 1 two kinds or more than two kinds of pre-connection materials are prepared into semi-solid blank or semi-solid slurry respectively; and 2 the semi-solid blank or the semi-solid slurry prepared in step one is put in a die cavity or below a roller to perform one-time composite formation under pressure. A material interface prepared by the method is good in combination, high in performance, small in product residual stress and high in production efficiency. Semi-solid formation is low in temperature, requirements on die materials are not high, and production environment is good. The semi-solid formation is high in mechanical property, requirements for the mechanical property can be satisfied, and the method for connecting the semi-solid materials into the whole is used in the field of material connection and formation.

Description

technical field [0001] The invention relates to the technical field of material connection and forming. Background technique [0002] Material connection is to connect two or more materials (including metals and non-metals, composite materials, compounds, etc.) together through certain process conditions to form a complete structure with certain performance. The material connection structure has the excellent properties of various materials, so it has been widely used in aerospace, space technology, nuclear industry, microelectronics, automobile, petrochemical and other fields. [0003] The progress of modern science and technology has increasingly increased the requirements for material science and engineering technology. The development of new high-performance structural parts and advanced connection technology has become an urgent problem for high-tech enterprises. areas are more evident. For example, the heat pipe structure in the aerospace field and the national produ...
