With the increase of the grainsizeof H68 brass, the critical plastic strain for the onset of serrations increases while the maximum stress amplitude of serrations decreases.
对于H68黄铜,随着晶粒尺寸的增大,出现锯齿屈服的临界应变量增大,锯齿波的最大应力振幅减小。

It is very important to determine reasonably the maximumgrainsize, graded sizes and gradation of the coarse aggregate.
