热裂

The Ni5Zr with low melting point forms because of Zr-rich liquid film will be maintained below 1180℃, therefore, solidification range of the alloy widens by 80℃ and the intenyal between the temperature at which the interdendritie feeding action disappears and the solidus temperature enlarges by 60℃....

在凝固过程中富Zr的液膜保持到低于1180℃的温度，结果使合金的凝固范围扩大了80℃。使失去枝晶间补缩的温度与固相线的温度范围扩大了60℃。这是含Zr含金热裂倾向大的原因之一。

General rules of adequate cold cracking tendentiousness larger ingot alloy and specifications, should improve casting speed; and greater tendency to hot crack ingot alloy and specifications, it should reduce the casting speed.

充足的冷裂纹倾向性较大的合金锭和规格的一般规则，应改善铸造速度和更大的热裂倾向合金锭和规格，应减少铸件的速度。

The hot cracking tendency of alloys increase with the increasing of temperature range of uncompensated stage.

浇注温度的提高可以降低合金的冷却速率，如果这种影响发生在合金不可补缩区，将降低合金的热裂倾向。

Chemical composition can influence the temperature range of alloys in uncompensated stage.

抽拉速率的提高可以增大合金凝固末期收缩速率，加大合金热裂倾向。

Low expansion resin is, prevents from casting defects, especially veining and hot tear caused from thermal expansion.

低膨胀树脂对解决铸造缺陷，特别是对毛刺、热裂尤为有效。

The metal melt around the oblique crack tip passivates the crack tip and inhibits the cracking trend of main crack source.

在瞬间超强脉冲电流作用下，裂尖前缘发生了强烈的绕流热集中现象，斜裂纹裂尖附近金属熔化，钝化了裂尖，阻止了干线裂纹源的开裂趋势。

Based on analysis to solidification process, it was proposed a new kind of hot cracking theory which was called theory about solidification contraction and its compensation.

本文针对空心叶片类铸件薄壁和在定向凝固过程中横向收缩受阻的特点，设计了定向凝固合金热裂倾向性薄板工字型精铸试样，并提出了。。。

Hot tearing is one of the most serious failures in production of steel castings.

热裂是铸钢件生产中最严重的铸造缺陷之一。

All the test results showed that this water-in-oil emulsion fracturing fluid posseses such advantages as good themal stability, good shearing stability, low filter loss, low hurt, good restrainting the inflation of clay material, easy breaking of emulsion and flowback and so on, and then it can replace the conventional oil base gel and be used in fracturing the low pressured and strong water sensitive reservoirs of Gars oil field, Qinghai Province.

研究结果表明，该油包水乳化压裂液具有热稳定性好、耐剪切、低滤失、低伤害、能够较好的抑制粘土水化膨胀以及易破乳返排等优点，可以代替常规油基冻胶压裂液用于尕斯油田中浅层强水敏、低压油藏的压裂改造。

This will lead to roll failure such as fire crack, surface crack, and fatigue failure.

这将会导致轧辊疲劳产生热裂、轧辊表面破裂或是疲劳层的产生。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
