Magnesium lanthanum alloy
mgla5 alloy
mgla25 alloy
mgla30 alloy
The invention relates to a method for preparing lanthanum magnesium intermediate alloy by high-energy ultrasound. The preparation method is: first, pure magnesium ingot is heated to melt in a crucible, the powdered rare earth lanthanum is wrapped in aluminum foil and added to the pure magnesium melt, and then the temperature is kept in the range of 700~720ºC for 20~30 minutes. The ultrasonic horn was extended into the melt for ultrasonic treatment. The ultrasonic time was 30~45 minutes, and the ultrasonic power was 400~800W. Refining and impurity removal, casting and sampling in the above temperature range. The technical effect of the invention is that the magnesium lanthanum intermediate alloy obtained by the invention has the advantages of stable content, effective avoidance of rare earth burning, reduction of oxidation inclusion and component segregation, etc., and the process is simple, safe and reliable, and convenient operation.
Research progress of rare earth lanthanum magnesium alloys
Magnesium alloy material is known as "green engineering metal structural material of the 21st century". As an important alloying element, lanthanum has the function of improving the casting performance of magnesium alloy, refining the grain significantly, and improving the mechanical properties and corrosion resistance of magnesium alloy. The effects of lanthanum on microstructure, mechanical properties, adhesion and corrosion resistance of magnesium alloys were reviewed.
A kind of aluminum silicon copper magnesium lanthanum titanium piston alloy
The alloy material is used in the manufacture of various pistons to replace the piston alloys currently in use with or without nickel. The alloy is based on aluminum - silicon - copper - magnesium alloy, adding trace elements of lanthanum, titanium and phosphorus to form a polyphase alloy microstructure, among which, the intermetallic compounds of iron are small fish bone, and the intermetallic compounds containing lanthanum and lanthanum hydrogen compounds are highly dispersed. The alloy is treated by metal mold casting, solution and aging. Piston body high temperature instantaneous tensile strength, good thermal volume stability, wear resistance, alloy added lanthanum, compared with the cost of adding nickel, at least 50%, simple process, no pollution, low energy consumption.
An aluminum-silicon copper magnesium lanthanum titanium piston alloy consisting of aluminum-silicon base with additional elements. The chemical composition (percent by weight) of the alloy is characterized by Si: 11 ~ 13%; Cu: 1 ~ 1.3%; Mg: 1 ~ 1.3%; La: 0.03 ~ 0.1%; Ti: 0.1 ~ 0.2%; P: 0.005 ~ 0.05%; The rest are Al.
