蠕化率对蠕铁热疲劳抗力的影响

Twisting and Vermiculating of Graphite during Its Growth Process in Cast Iron

铸铁中石墨生长时的弯曲与蠕化

The influence of the vermiculating rate on the thermal fatigue resistance . of vermicular graphite iron is studied with the Uddeholm thermal fatigue testing method .

用Uddeholm热疲劳试验方法，研究了蠕化率对蠕铁热疲劳抗力的影响。

Under the conditions of fast heating , fast cooling and thermal cycling with larger temperature difference , it is concluded that ( 1 ) under appropriate strength and toughness , in creasing the vermiculating rate can enhance the thermal fatigue resistance of vermicular graphite iron ;

在快速加热、快速冷却以及较大热循环温差的服役条件下得出：（1）当强韧性相当时，提高蠕化率可提高蠕铁的热疲劳抗力；
