不同機(jī)器的不同拉伸試驗(yàn)機(jī)...

與拉伸試驗(yàn)機(jī)和材料本身有關(guān)的因素：不同的拉伸試驗(yàn)機(jī)對(duì)不同的材料進(jìn)行拉伸試驗(yàn)，但是用戶根據(jù)材料的不同選擇的試驗(yàn)機(jī)型號(hào)也不同。 以下是材料對(duì)拉伸機(jī)的影響：材料化學(xué)成分，金相組織，晶粒大小以及是否存在冶金缺陷，例如裂紋，爐渣夾雜物，偏析，白點(diǎn)和非金屬夾雜物等超出標(biāo)準(zhǔn)，或者 熱處理過(guò)程中產(chǎn)生的缺陷會(huì)影響樣品制造商的性能。 ，這是拉伸試驗(yàn)機(jī)被廣泛使用的地方，這也使得...

因此，測(cè)試人員可以判斷...
