下面六篇文章是从黑龙江省机械工业系统理化经验交流会有关金相方面经验交流资料中选登的。其中《高速钢的低倍组织试验研究》一文对工具制造单位很有参考价值。《大截面钢的低倍电解腐蚀方法》一文介绍了由于实现半机械化,大大改善劳动条件,为国家节省大量原材料的显著效果,很有推广价值。《钢的奥氏体实际晶粒度显露方法》一文所介绍的方法操作简单,节省时间,有实用价值。《几种显示钢的奥氏体晶粒度方法比较》一文有一定参考价值。《拉伸速度实验小结》一文阐述了拉伸速度对测得准确结果的影响。《氮化件质量检查方法及标准的拟定草案》一文可供有关氮化处理单位参考。
The following six articles from the mechanical and chemical industry in Heilongjiang Province, the physical and chemical exchange experience exchange experience on the gold side of information selected. One of the “high speed steel microstructure experimental study” article is very useful reference to the tool manufacturing unit. The article “Low Electrolytic Corrosion of Large Cross-section Steels” presented a great promotional value due to the realization of semi-mechanization, greatly improved working conditions and significant national savings in raw materials. “The actual grain size of austenite steel exposure method” article describes the method is simple, save time and have practical value. “Several kinds of comparison of austenite grain size shows that the steel” article has some reference value. “Tensile speed experiment summary” article elaborates the impact of tensile velocity on the measurement accuracy. “Nitride piece quality inspection methods and standards draft” is available for reference nitriding unit.
