内容简介本文译自美国《电渡工程手册》第十三章。着重论述电镀工作者需要关心的两个方面:金相学和机械冶金学。本刊上期登载了“前言”和“金属及合金的基本特征”、“金属和合金的机械性能”两个小节。余下的六个小节本期续完。这六个小节是:“内应力”“镀层的强度与延展性的测定”“金属之硬度”“镀层的晶粒尺寸”“热处理”和“氢脆”。
Content brief introduction This article is translated from the United States, “Electric Crossing Engineering Manual” thirteenth chapter. Focusing on the electroplating workers need to be concerned about two aspects: metallography and mechanical metallurgy. This issue of the magazine published the “Foreword” and “the basic characteristics of metals and alloys,” “metal and alloy mechanical properties” two sections. The remaining six sections are completed in this period. The six subsections are: “Internal Stress” “Determination of Strength and Ductility of Coating” “Hardness of Metal” “Grain Size of Coating” “Heat Treatment” and “Hydrogen Embrittlement”.
