摘要
Abstract
The substandard reason of low-temperature toughness of 09MnNiDR cone was analyzed.It was caused by microstructure segregation of steel.After appropriate heat treatment which changed the material′s microstructure and refined grain further,the impact toughness highly increased.However,gener-al heat treatment could not change the microstructure segregation and non-uniform impact absorb energy.关键词
