Abstract
The present invention includes a process for manufacturing metal sheets or plates and a machined metal part as well as machined products, structural components and their uses in various applications. Manufacture of a metal sheet or plate by a process of the present invention comprises casting of a rolling ingot, optionally followed by homogenization, one or more hot or cold rolling operations, optionally separated by one or more re-heating operations, to obtain a sheet, or plate and optionally one or more sheet or plate cutting or finishing operations. The sheet is pre-machined on one or both sides so as to obtain a pre-machined stock, and subjected to solution heat treatment, quenching treatment, and optionally, one or more of the following steps: controlled stretching, aging treatment, and/or cutting.
