摘要
介绍了用仪器化冲击试验机研究模具钢冲击韧度。指出,用冲击力-位移曲线测出的裂纹稳定扩展功的大小,反映了材料的韧性好坏,弥补了用冲击总功作评估的不足。
In the paper the impact toughness of the die steel is studied by the instrumentlized impact test machine.It shows that the crack energy of stable propagation measured by the impact-displacement curve reflects the quality of the toughness of the material and remedies the disadvantage evaluated by the total impact work.
