Numerical Methods for Safeguarding the Performance of the Quenching Process

A new numerical technique for testing and evaluation of quenching media and quenching systems is outlined. The measured time-temperature samples as a result of cooling curve test are analyzed by the new software developed, in order to characterize quantitatively the quenchants. The method applied is based on Fourier analysis. Examples for evaluation and comparison of cooling performance of quenchants are presented the applicability of the computational technique.

用于钢材及其热处理工艺选择的计算机信息系统

文章综述了“相变—性能预测(TRANSPROPP)计算机信息系统的结构及应用。该系统由五部分组成:国际数据库的利用、国内外钢材标准数据库、热处理方法数据库、钢材性能数据库、和数据处理软件系统,本文着重讨论最后两部分。钢材性能数据库存于计算机文件中,可检索的内容包括:工件的尺寸或类型、钢材的牌号及成分、熔炼炉号、拉伸及屈服强度、硬度、断裂韧性、淬透性曲线等。已经从金属加工工业和考虑各种工程零件,收集了钢材性能数据。数据处理软件系统为一组特殊的计算机程序,其作用就是在数据不全的情况下,用于交互预测钢材性能及设计热处理工艺。文中举例说明了该信息系统应用的可能性。
