Causes of defects due to heat treatment and preventive measures: countermeasures for overheating, quenching, and cracking.
[Reprint Private Spring Preparatory School Lecture 33] What you need to be careful about is overheating! An introduction to defects that are likely to occur during heat treatment.
Today, in the sense of a final review, let's study the defects that are likely to occur during heat treatment. The first thing to be cautious about is overheating. This occurs when steel is unnecessarily heated to a temperature above the specified level, which not only damages the fuel but also accelerates the wear of the furnace. Overheated materials are prone to decarburization, oxidation, and grain coarsening, leading to cracking and making the mechanical properties more brittle. In the heat treatment of springs, there is also a chance of overheating during shaping and quenching heating. How can we prevent this? *For detailed content of the article, please refer to the PDF.
