THE HEAT-TREATMENT OF STEEL

感兴趣的朋友，请进来英译汉
下面这段英文技术资料，摘自THE HEAT-TREATMENT OF STEEL （钢的热处理），by EDWIN GREGORY and ERIC N. SIMONS，LONDON SIR ISAAC PITMAN & SONS，LTD. Second edition 1958. CHAPTER Ⅲ（第三章）Spheroidizing Ball-bearing Steel，Austermpering and Martempering(滚珠轴承钢的球化处理、贝氏体等温淬火和低于Ms点的分级淬火)。感兴趣的朋友，可以把它译成汉语。大家相互交流，相互提高。
Austempering comprises raising the temperature of a steel until its structural condition is completely austenitic, i.e. well above its upper critical point,and then immersing it in a molten lead or salt bath heated to and rigorously maintained at a chosen temperature, which cools it quickly to this temperature,but is above the temperature at which the austenite in the steel normally changes to hard martensite when quenched in oil or water at ordinary temperature.The bath temperature is maintained, in short,below the change of the steel,but still higher than that at which  martensite forms under more drastic quenching conditions.The austenite is not retained,of course,but is gradually tempered,hence the term austempering, yielding a structural state comparable with ,but perhaps finer than ,that obtained by the more orthodox hardening and tempering treatments.The result is a tougher steel for a specific hardness than can be obtained by the  normal method of hardening followed by tempering.
It is claimed,quite legitimately,that austempering minimizes cracking and distortion during heat-treatment.

就这么一点没多的吗？

我的这个帖子没人顶呀。没人顶，我来顶。我来把这段英文译成中文。不当之处，望网友们指正。译文如下：
贝氏体等温淬火是将钢的淬火加热温度提高到一个使其组织结构完全奥氏体化的温度,也就是远高于它的上临界点上,然后浸入到一个预先选定的温度的铅浴或盐浴中，并迅速冷却到这一温度。在这一淬火温度下，如果油淬或水淬，那么钢中的奥氏体就会转变成坚硬的马氏体。总之，铅浴或盐浴的温度要低于钢的转变温度，但要高于急冷状态下的马氏体形成温度。奥氏体消失了，并逐步得到回火。因此，贝氏体等温淬火的组织状态比起常规淬火和回火的组织状态要细致的多。结果是，在特定硬度下，钢的韧性要比常规淬火和回火高得多。
严格地说，贝氏体等温淬火降低了热处理过程中的变形和开裂。

我想要这本英文书，楼主能不能发给我?谢谢

低调的温度

有没有这本书整本的？
