Benefits of technology

This patented technology allows for more efficient use of recycled materials such as Mg or Al metal while maintaining their quality level. By adding specific elements called ULTRs (ultraviolet reactive particles) into these metals, they can help break up any impurities that may be present on them before melting it down again. These technical improvements make new types of material possible with fewer defective parts than traditional ones made from raw materials like iron powder.

Problems solved by technology

This patented technical solution describes various methods for recovering valuable metals (M) through melting processes like casting, milling, etc., without generating significant amounts of metal waste. These techniques involve creation of strong solid-state regulated repairs called solids, which help prevent corrosion damage and improve their durability over time. Additionally, these solutions aim to provide a way to control the formation of oxides within the recovered products while maintaining desired physical characteristics.

Embodiment Construction

[0028] In order to make the objects and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0029] The test material selected in this example is AZ31B wrought magnesium alloy, and the composition is shown in Table 1. The magnesium alloy as-cast billet is turned into chips of a certain size by a lathe. In this specific implementation, in order to study the morphological distribution of the oxide phase in the solid-phase regenerated magnesium alloy, the AZ31B magnesium alloy as-cast billet is turned into ultra-thin chips. , its size is: (0.01-0.02) mm × (1.48-1.52) mm × (10-200) mm, in order to increase the number of oxidized phases in the regenerated magnesium alloy and facilitate observation and analysis. , . In addition, in o

Abstract

The invention discloses a method for characterizing oxidation phase of a solid-phase regenerated AZ31B magnesium alloy. An as-cast blank of the AZ31B magnesium alloy is turned into ultrathin chips, and the ultrathin chips are placed in a chamber electric resistance furnace for oxidation treatment, heated slowly to 673 K in an air atmosphere and subjected to heat preservation for 2 h; the ultrathin chips subjected to oxidation treatment are loaded to a mold with the diameter being 40 m and subjected to cold pressing with a unidirectional pressure method, and a billet is formed, wherein process parameters of billet forming through cold pressing are as follows: pressure is kept at 350 MPa, and pressure is kept for 60 s; the mold loaded with the blank is placed into a heating furnace, heated to 673 K, subjected to heat preservation for 20 min and extruded at the extruding rate of 0.2 mm s<-1>, and a bar is obtained through machining; a microscopic structure is observed. The oxidation phase is observed successfully through an optical microscope and a scanning electron microscope.
