一、前言随着我国科学技术和国防工业的发展,特别是大型汽轮机工业、航空工业、原子反应堆和宇航事业的迅猛发展。日益迫切的提出了高温强度的测试问题,高温电阻应变片则是高温应力测量中比较广泛使用的一种较好的测试元件。高温应变电阻合金就是为了满足制作高温电阻应变片进行高温应力测量的一种合金体系。目前根据电阻应变片使用温度的要求,应变电阻合金使用温度范围可大致分成六类:
I. INTRODUCTION With the development of our country’s science and technology and national defense industry, especially the rapid development of large-scale steam turbine industry, aviation industry, atomic reactor and aerospace industry. More and more urgent to put forward the test of high temperature strength, high temperature resistance strain gauges are widely used in high temperature stress measurement of a better test component. High-temperature strain resistance alloy is to meet the production of high-temperature resistance strain gauge high temperature stress measurement of an alloy system. At present, according to the resistance strain gauge temperature requirements, strain resistance alloy temperature range can be roughly divided into six categories:
