If the workpiece is heated to a higher temperature and the aging treatment is carried out in a short time, it is called artificial aging treatment. The Function And The Production Of Ceramic Bulletproof VestIf the workpiece is stored at room temperature or under natural conditions for a long time, the aging phenomenon occurs, which is called natural aging. Aging treatment. Casting Vacuum Heat Treatment ProcessThe purpose of aging treatment is to eliminate the internal stress of the workpiece, stabilize the structure and size, improve mechanical properties, etc. Aluminum aging found that the hardness of this alloy after quenching is not high, but after being placed at room temperature for a period of time, the hardness will increase significantly. Copper wire workshop design and vacuum heat treatmentThe phenomenon came to be known as precipitation hardening. This discovery has generated great interest in the engineering community. Subsequently, people successively discovered some aluminum alloys, copper alloys and iron-based alloys that can be strengthened by aging treatment, creating a new strengthening method that is fundamentally different from general steel quenching and strengthening - aging strengthening. During 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 melting the alloy. The allowable deviation of the heating temperature for solution treatment of many aluminum alloys is only about 5 °C. Vacuum Heat Treatment Furnace For Molds
