摘要
在自行研制的高速旋转盘式间接杆杆型冲击拉伸试验装置上,采用扁平哑铃状的试件,用耐高温无机胶使试件两端分别与输入杆和输出杆的叉口粘接;采用自行研制的高温炉对粘接后的试件进行快速接触加温,初步形成了800℃以下的高温冲击拉伸试验技术.对SUS304不锈钢板(厚度为1.1mm)实施常温至537℃的冲击拉伸试验和准静态拉伸试验.初步探索表明SUS304不锈钢是温度相关和应变率相关的材料,且在准静态和高应变率加载下均出现了高温脆化现象(室温至537℃).
A high temperature tensile impact experimental technique (under 800℃) is preliminarily developed. A kind of refractory inorganic adhesive is used to connect the flat dumbbellshaped specimen and the input/output bars of the rotating disk barbar tensile impact apparatus.A high temperature furnace is designed to heat the specimen by means of rapid contact heating.The quasistatic and tensile impact experiments are performed to study the mechanical behavior of stainless steel plate SUS304 at different temperatures ranging from 25℃ to 537℃.The experimental results show that the stainless steel SUS304 is a temperature and strainrate dependent metal.A high temperature embrittlement phenomenon is observed at both quasistatic and high strain rate loading conditions.
