High-strength high-plasticity ultralight LA141 magnesium lithium alloy deep-cold rolling process

The invention relates to the technical field of magnesium-lithium alloy processing, in particular to a high-strength high-plasticity ultralight LA141 magnesium lithium alloy deep-cold rolling process.The aim is to provide the high-strength high-plasticity ultralight LA141 magnesium lithium alloy deep-cold rolling process which is more excellent compared with a traditional rolling deformation process is provided. The process comprises the following steps that raw materials are prepared according to alloy compositions and contents, smelting is carried out to obtain a magnesium-lithium alloy ingot, homogenizing treatment is carried out, deep-cooling rolling is carried out on a magnesium-lithium alloy, and detecting and analyzing are carried out. According to a deep-cold rolling magnesium-lithium alloy technology, the preparing method is simple and reliable in process, is suitable for processing large-scale magnesium-lithium alloy industrial samples, has high efficiency and has an important practical value.
