The main functions and purposes of alloy heat treatment are as follows: one is to improve the process performance of the formed parts and ensure the smooth progress of the subsequent processes; the other is to improve the performance of the parts and give full play to the potential...
Although rheo squeeze casting can improve and improve the mechanical properties of 7075 alloy parts and eliminate some macro segregation, the micro segregation is still widespread, which reduces the grain boundary strength and leads to the low overall properties of rheo squeeze casting parts. 7075 alloy is a kind...
Heat treatment is usually used in strengthening and toughening treatment of ductile iron. The heating temperature of most heat treatment processes is higher than the upper limit of critical eutectoid temperature (AC upper limit) of nodular iron heating, which involves the austenization process of nodular iron matrix structure, which...
Dredger is a common dredger, working in sand and silt. It is generally used to excavate various kinds of silt, soft clay, sand and hard clay underwater. With the improvement of dredging engineering efficiency, dredger is developing towards large and super large scale, and the size of lock ring...
