Impactvalue is one of the criteria to evaluate material toughness.
冲击值是评价材料韧性的指标之一。

For the difference of ship steel low temperature impactvalue, the effects of chemical composition, inclusion and microstructure of the refined and unrefined steel are analyzed.
针对精炼与非精炼船钢低温冲击值的差异，分析了两种钢的化学成分、夹杂物和显微组织等对冲击值的影响。

However, large grain size and continuous grain boundaries combine to produce stress concentrations, thus lowering the plasticity and impactvalue of alloy after solution and aging treatment.
