Abstract: The present invention discloses a method for processing a highly alloyed aluminum alloy sheet with a high rolling yield, including the steps of cold rolling and hot rolling of an alloy sheet followed by heat treatment. The highly alloyed Al—Cu—Mg—Ag alloy sheet is subjected to short-time solution treatment and quenching at high temperature for multiple times by increasing the solution treatment temperature and shortening the solution treatment time. In this way, the mechanical properties of the alloy at room temperature and high temperature match with or even exceed those of a conventional alloy subjected to long-time solution treatment at high temperature. The present invention implements multiple times of short-time continuous solution treatment and quenching of a highly-alloyed coiled aluminum alloy sheet. This prevents a large amount of scraps caused by the conventional processes of segmented solution treatment and quenching of the coiled material and stretching straightening treatment.

Abstract: Methods of manufacturing or repairing a turbine blade or vane are described. The airfoil portions of these turbine components are typically manufactured by casting in a ceramic mold, and a surface made up of the cast airfoil and at the least the ceramic core serves as a build surface for a subsequent process of additively manufacturing the tip portions. The build surface is created by removing a top portion of the airfoil and the core, or by placing an ultra-thin shim on top of the airfoil and the core. The overhang projected by the shim is subsequently removed. These methods are not limited to turbine engine applications, but can be applied to any metallic object that can benefit from casting and additive manufacturing processes. The present disclosure also relates to finished and intermediate products prepared by these methods.

Abstract: A primary heating band is applied to a weld to control a microstructure and hardness of the weld and uniformity of the structure to realize micro-control of the residual stress; an auxiliary heating band is applied a certain distance away from the weld to generate compressive stress on an inner surface of the weld to realize macro-control of the compressive stress. Reinforcement with a rib plate is eliminated, and a labor intensity and a construction period are reduced. The method reduces deformation near the weld and transfers the largest deformation to a non-weld zone; by applying the auxiliary heating and strictly controlling a time interval between primary heating and auxiliary heating, the structure is improved and the welding residual stress is controlled at the same time; a local heat treatment effect is optimized, and a small tensile stress or compressive stress is generated on the inner surface of the weld.
