Aluminum aging found that the hardness of this alloy was not high after quenching, but after a period of time at room temperature, the hardness increased significantly. This phenomenon was later called precipitation hardening. This discovery has generated great interest in the engineering community.Low temperature carburizing of 9Cr18 stainless steel surface Later, people successively discovered some aluminum alloys, copper alloys and iron-based alloys that can be strengthened by aging treatment, and created a new strengthening method that is essentially different from general steel quenching strengthening - aging strengthening. Solidification before aging treatment During the solution treatment, the heating temperature must be strictly controlled so that the solute atoms can be dissolved into the solid solution to the maximum extent without causing the alloy to melt.Pressureless Sintering of Silicon Carbide Ceramics The allowable deviation of heating temperature for solution treatment of many aluminum alloys is only about 5°C. For artificial aging treatment, the heating temperature and holding time must be strictly controlled in order to obtain an ideal strengthening effect.CS SERIES SCISSOR TYPE METAL CUTTING SAW CS-220 Sometimes segmented aging is used in production, that is, first keep warm for a period of time at room temperature or a temperature slightly higher than room temperature, and then keep warm for a period of time at a higher temperature. Doing so sometimes yields better results. This series of electric resistance furnaces is a periodic operating furnace, which can be used for heat treatment such as tempering of steel parts and quenching and aging of aluminum alloy parts.HORIZONTAL METAL BAND SAWING MACHINE
