toughness value

This article introduces the full size anti-crack burst test was conducted during the construction of Canadian Alliance Gas Transmitting Pipeline, and the result shows that the actual anti-crack toughness value inosculated to the calculated value from TCM hyperbolic model and Leis modification method in Battelle Research Institute, USA.

本文介绍了加拿大建设Alliance输气管道时进行的全尺寸止裂爆破试验，实验结果表明，实际止裂韧性值与用美国Battelle研究所的TCM双曲线模型和Leis修正方法计算出的预测值相吻合。

Room temperature fracture toughness was measured by three-point bending test and the KQ value for the DS condition was much higher than that for the as-cast condition. The maximum fracture toughness was 19.7MPam~ ( 1/ 2).

三点弯曲试验表明，定向凝固后试样的室温断裂韧性也得到了明显的提高，K Q最高达到了19.7MPam~（1/2）。

Characteristics such as high impact, toughness and good surface appearance are key value drivers.

诸如高抗冲击性 、 高硬度以及优美的外观都是提升最终产品价值的关键因素.
