落锤试验与基准无延性转变温度
DROP-WEIGHT TEST AND REFERENCE NIL-DUCTILITY TRANSITION TEMPERATURE
摘 要
落锤试验是工程领域中对金属材料进行检测和评判的一种重要方法。而国内在试验标准、方法和评判标准等方面与国外均存在差异。为了促进技术交流，介绍了国际通用的落锤试验方法、标准选用、无延性转变温度与基准无延性转变温度的关系以及在实际应用中的注意事项。
TNDT(无延性转变温度)
RTNDT(基准无延性转变温度)

RTNDT (reference nil-ductility transition temperature)
Abstract
The dropweight test is an important method for enginccring field to testing and evalation the metallit material property. There are some differences in test standards, methods and judgments between China and other countries. In order to promote the technique development, we introduce conventional drop-weight test, selection of standard, the relationship of TNDT and RTNDT, and the application instances.
