介绍一本好书《工程用钢的组织与性能图册》——由康大韬、郭成熊编译,机械工业出版社出版的新书《工程用钢的组织与性能图册》是一本实用性很强的工具书。它汇集了172个钢种在各种截面尺寸和不同冷却条件下获得的心部金相显微组织、经淬火和不同温度回火后,相应截面尺寸零件心部硬度以及马氏体与贝氏体转变动力学过程等大量数据。该手册最大的特点是罗列了5～500、0.1～2000mm大截面钢材在水、油和空气中冷却的组织和性能以及各种尺寸工件空冷时的冷却速度。这些都是在以往的手册中罕见的。用该书中提供的数据和计算图表,可求出方截面零件或板状件的等效直径,以及圆棒表面和不同截面处的等效直径,进而可求出其在不同冷却条件下的组织和性能。
Introduce a good book “Atlas of organization and performance of engineering steel” - Compiled by Kang Da Tao, Guo Chengxiong, Mechanical Industry Press published a book “Atlas of organization and performance of engineering steel” is a very practical reference book. It brings together the heart of 172 steel in various cross-sectional size and cooling conditions obtained microstructure, after quenching and tempering at different temperatures, the corresponding section size core hardness and martensite and bainite transformation Kinetic process and other large amounts of data. The most important feature of this manual is a list of the microstructure and properties of 5 ~ 500,0.1 ~ 2000mm large section steel in water, oil and air cooling and the cooling rate of air-cooled workpieces of various sizes. These are rare in the past manuals. Using the data and calculations provided in this book, the equivalent diameter of a square section or plate can be found, along with the equivalent diameter at the surface of the rod and at various cross-sections, so that it can be obtained under different cooling conditions Organization and performance.
