Abstract
The aim of this study was to investigate the effect of temperature and time of homogenization treatment on the microstructure, distribution of alloying elements and hardness of the novel Co-based superalloy Co-7Al-7W-4Ti-2Ta. For this purpose, the specimens were first homogenized at 1250 and 1300 °C for 2, 4, 6 and 8 hours and then water-cooled. Subsequently, the specimens were subjected to hardness testing and microstructural examinations by optical and electron microscopy.

均匀化处理对co - al - w - ti - ta基高温合金合金元素分布、显微组织和硬度影响的研究
研究了均匀化处理温度和时间对新型co基高温合金Co-7Al-7W-4Ti-2Ta显微组织、合金元素分布和硬度的影响。为此，首先将样品在1250和1300°C下均质2、4、6和8小时，然后水冷。随后，用光学显微镜和电子显微镜对试样进行硬度测试和显微组织检查。*یکینورتکلاتسپ،تابتاکملوئسم::m_morakabati@mut.ac.ir噢问oa de D fr om ja m e . iu t.a c .红外4:0 7 ir S T o n W ed ne sd ay D ec em是30 th 2 2 0 r (D o我:71 76 / ja m e。39。4。2。2 16 21)
