| Abstract: | In order to improve operating performance （wear resistance, high hardness and better impact toughness） of axis, test research of 17-4PH stainless steel is conducted. Through rational control of chemical composition and adjusting heat treatment system,heat treatment process is optimized. After heat treatment analysis test of mechanical properties of materials, microstructure amt X-ray is proceeded. Analyzing experimental data, observing microstructure of material and studying the influence of heat treatment process on material structure and wear resistance, it is founded out that a solid solution at 1 050 ℃ after aging ＋520℃ hardness, hardness and wear resistance are best and impact toughness is better, the performance requirement is met. |
