介绍了金属材料试样制备与力学性能试验结果的相关性。对国家标准中关于力学性能试验试样取样和机加工的要求、力学试验取样和制样过程中需要注意的问题、机加工质量的检验等问题进行了讨论。结果表明金属材料试验试样的制备与力学性能试验的结果有着非常密切的相关性,由于这个原因,力学试验试样的取样和机加工必须严格按照国家标准的要求进行,机加工后必须检验加工质量,以保证力学试验结果的正确性。

The relativity for preparation of specimens and results of mechanical testing for metallic materials was introduced in a systematic way. The requirement of Chinese standards to location of sampling and process machining of test pieces for mechanical testing ,the needing attention problems of the process for sampling and preparation of test pieces for mechanical testing,the examine of quality for process machining etc. were also discussed. The results showed that the relativity for preparation of specimens and results of mechanical testing for metallic materials were very close relationship. For the reason the location of sampling and process machining of test pieces for mechanical testing must be in processing strictly according to the requirement of Chinese standards. After the process machining must inspect the quality of processing. The exactitude of the results for mechanical testing is guaranteed.
