In this paper,the mechanism of workpiece burn during grinding of casehardened steel and titanium alloys was studied by the use of SEM,EPMA,XPS and the metallograph analysis.

本文应SEM,EPMA、XPS相显微分析等技术研究了表面硬化钢和钛合烧伤机理。

The cross section morphology and skin-core structure of PAN fiber in wet-spinning are analyzed by the means of electron probe microanalyser (EPMA) and scanning electron microscope (SEM).

结果表明凝固浴温度会影响初生纤维面形貌与芯部结构。
