我厂在进行16Mn 钢板的高温机械性能测试工作中,曾先后制作过五套测定σ0.2的装置,在试制过程中,经过“由实践到认识,由认识到实践的多次反复”逐步改进,逐步完善,终于制成了目前这一套较为理想的高温引伸仪,实践证明,它既准确可靠,又简易方便,已圆满地应用于日常产品的检验工作。高温引伸仪的主要用途是高温状态下测定试样在承受轴向拉应力时,测出具相应的轴向变形量。该仪
In the process of testing the high-temperature mechanical properties of 16Mn steel plates, we have successively produced five sets of devices for the determination of σ0.2. Through trial and error, Gradually improve and gradually improve, and finally made this set of more ideal high temperature extensometer, proved that it is accurate and reliable, but also easy and convenient, has been successfully applied to the inspection of routine products. The main purpose of the high temperature extensometer is to determine the corresponding axial deformation when the specimen under high temperature is under axial tensile stress. The meter
