critical quenching rate的意思|示意

No matter how cool the quenching medium may be, if the heat inside a large piece cannot escape faster than a certain critical rate, there is a definite limit to the inside hardness.

无论淬火介质怎么冷，如果在大工件中的热量不能比特定的临界速率更快散发，那它内部硬度就会受到明确限制。

The quenching operation is the most critical part of the heat treatment since too slow a rate of cooling might give rise to either soft spots or quenching cracks.

自太慢地冷却的比率也可能引起软的地点或淬熄裂缝之后，淬熄操作是热处理的最紧要关头的部份。

Abstract The critical cooling rate of steel is very important in heavy plate quenching process, and it is the basis of the cooling process.

在中厚板淬火工艺中，钢的临界冷速是非常重要的参数，是制定冷却工艺的基础。
