摘　　要：316缸盖因进气道(薄壁)部位珠光体含量低造成该部位在使用中出现了裂纹,对其薄壁部位比厚壁部位珠光体含量低的原因进行了分析,并试验研究了添加Sn合金元素提高珠光体含量的措施。The low pearlite content on the air inlet （thin-wall） site for 316 cylinder head causes cracks for low pearlite content at thin-wall site than that of the thick wall site were analyzed. And the measures improved by adding Sn alloy elements were studied by experiment.

关 键 词：缸盖 珠光体 裂纹
