impact toughness

基本解释

Welding the utmostly important structure, such as petroleum platform on ocean, pressure containers, etc. The low-temperature impact toughness of deposited metal is extremely strong.
焊接十分重要的结构，如海洋石油平台、压力容器等，熔敷金属低温性能优异。
The anisotropic characteristic which usually exists in materials disappeared completely especially the notch - impact toughness at the transverse direction was increased by 2-3 times.
因此在通常材料中所存在的各向异性完全消失，特别是缺口冲击韧性横向性能值提高了2～3倍。
The extra-cryogenic impact toughness and influence factors of the high-Mn austenitic steel are studied by means of the Charpy V-notch impact test and the SEM fractured appearance analysis.
本文通过在超低温下的V型缺口夏比冲击试验和SEM断口分析研究了高锰奥氏体钢的冲击韧性及其影响因素。

韧性
The impact toughness of this kind of steel will bedescent when it is aged at 580 660℃.
580～660℃时效降低该钢的冲击韧性。
冲击韧度
The impact toughness of the alloy with Y content increasing linearly increased.
而合金的冲击韧度随Y含量的增加呈线性上升。
