Abstract

The invention discloses a high-temperature-resistant aluminum-based composite material for drill pipes and an additive manufacturing method. The composite material consists of: a base material, a high volume fraction SiC whisker reinforcement and an in-situ SiC+AlN hybrid reinforcement, the base material The mass percentages of the components are Cu3.8-4.9%, Mg1.2-1.8%, Mn0.30-0.90%, the rest is Al, and the SiC whisker reinforcement accounts for 20-30% of the mass percentage of the base material. The in-situ SiC+ The AlN hybrid reinforcement accounts for 5-10% of the mass percentage of the base material.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a high-temperature resistant aluminum alloy composite material and a manufacturing method. Background technique [0002] With the increasing population of social development, the demand for resources is increasing, and the near-surface resources have been over-exploited. In order to meet the needs of social development, it is necessary to search for resources deep in the earth. When the drilling is deepening, it is necessary to continuously connect the drill pipe to extend the drill string, and its self-weight continues to increase. It is very difficult to complete the drilling of deep and ultra-deep wells only by developing large-scale drilling rigs. Especially when the drilling exceeds a certain depth, the self-weight of the drill string can This will cause aging damage to the drill pipe, not to mention the harsh working conditions such as long open hole section, poor stabi...
