摘要
研究了淬火温度及冷却方式对１６ＮｉＣｏ钢微观组织和性能的影响，结果表明：该钢不同温度淬火风冷与油冷后，随淬火温度的提高，性能变化趋势相近，强度至８００℃～８３０℃达最大值，而后开始降低，８６０℃淬火冲击韧性为最高。８６０℃油淬与８３０℃风冷相比，强度下降不多，冲击韧性提高幅度比较大，并且随淬火温度的增加，两个强度指标之间的差别越来越大。
In this paper,the influences of quenching temperature and cooling on the microstructure and proper-ties of 16NiCo steel were studied. The results show that with increasing the austenitizing temperature thevariations of properties of oil or air-blast quenching are similar At 800～830℃ quenching, the strengthreached to a maximum value. At 860 ℃ quenching,impact tougness is the highest. Comparing 860℃ oilquenching with 830℃ air-blast quenching,the impact toughness was improved fairly with a slight decreasein strength.
