In the world, the use rate of precision steel pipe is very high, at home or abroad, precision steel pipe occupies a very important position in the whole pipeline material.According to the current market development, there are more than 200 large-scale manufacturers of precision steel pipes in China. Meanwhile, the annual output is constantly improving.And the technology of precision steel tube is also in constant improvement, relative to the previous process is more mature.Shandong liaocheng ronghe metal products co., LTD. Recently produced precision steel pipe, product quality has been developed and improved, for the inner hole and the size of the outer wall have strict requirements, in order to standardize and ensure the quality of precision steel pipe.


Through solid solution treatment and aging treatment in different time to get 5 kinds of heat treatment state of WE43 magnesium alloy samples, and then separately carries on the static mechanical performance test, microstructure and fracture morphology observed by SEM, the microstructure observed by optical microscope, using optical microscope and corresponding fracture microstructure, and analyzed the solid solution and aging heat treatment on microstructure and mechanical properties of WE43 magnesium alloys.


WE43 is mg-re alloy, where W is the code name of element Y, E is rare earth elements, 4 is the mass percentage of element Y, 3 is the mass percentage of the following rare earth elements.The general composition of WE43 is mg-4% y-3.3% RE(Nd, Gd) -0.5zr %.
