焊后,大量M6C在晶内弥散析出,在晶界和孪晶界上不连续析出,原有的碳化物长大。
After welding, a large volume fraction of tiny M6C precipitates in the matrix is discontinuously dispersed in the grain boundaries and twin boundaries, and the original carbides become bigger.
同时也使得连续析出在很短时间内就开始发生,并且在晶粒内部与不连续析出互相交织在一起进行。
Meanwhile, it made the continuous precipitation initiate very quickly and tangled up with the discontinuous one with in the interior of the grains.
