| Abstract: | Dimension change rate of 15-5PH maraging steel after ageing in the temperature range of 482-621 ℃ was investigated. Welding coefficient and the hardness of the steel after solid solution and ageing were also measured. The dimension change rate of the 482 ℃ aged specimen is less than 0.11% and the welding coefficient is more than 0.969. The hardness of solid solution by water cooling is the lowest,but the aged hardness is the highest,while the hardness of solid solution by air cooling is the highest, but the aged hardness is the lowest among the three solid solution cooling methods of water, oil and air. |
