中文摘要:
      研究了PtRhMoReCr高温电阻应变合金铸态组织、退火组织、电阻-温度特性、抗氧化性及物理性能。结果表明,高频感应熔炼时,采用特殊冷却结晶器制备的合金铸锭可以避免出现穿晶组织,得到易于加工的等轴、细小的柱状晶;PtRhMoReCr合金1200℃的氧化增重量较低,高温抗氧化性能优于其他同类型合金;合金具有较高的电阻率和抗拉强度等综合性能;在0~1000℃温度区间,合金的电阻-温度保持线性关系,PtRhMoReCr合金可将材料测温范围从0~900℃拓宽到0~1000℃。
英文摘要:
      The cast structure, annealing structure, resistance-temperature relationship, oxidation resistance and physical properties of the PtRhMoReCr high temperature resistance strain alloys were studied. The results showed that the alloy ingot prepared by a special solidification method could avoid the occurrence of trans granular structure during high-frequency induction melting and had easy-to-machine equiaxed and fine columnar crystals. The PtRhMoReCr alloy had low oxidation weight gain at 1200℃, and its high temperature oxidation resistance was better than other similar alloys. The alloy also had high resistivity and tensile strength. The resistance-temperature linear range of the alloy increased from 0~900℃ to 0~1000℃.
