Abstract

This paper studies the influence of different homogenizing process on the heating method of extrusion by means of metallographic microscope and eddy current conductivity meter. The results show that there are a large number of rich-Fe/Mn particles in 6351 alloy matrix by homogenizing in 560 °C. The rates of cooling after homogenizing have little effect on the long-time heating and heat-preservation heating before extrusion. The method of heating at a temperature higher than 500 °C before extrusion and then cooling in air is beneficial to the low-temperature and high-speed extrusion of 6351 alloy. If the total time of heating and extrusion is within 10 min, the samples which cool rapidly after homogenizing can be extruded at low-temperature and in a high-speed with the eddy-current heating.
