Improvement of Etching Method of Macroscopic Metallographic Examination Based on TRIZ Theory

摘要

Metallographic examination is a traditional technology. In this paper, etching method of macro inspection of metallographic was set as an example. Through analyzing the example by Su-Field Model and Physical Contradictions, we convert a practical problem into a TRIZ problem, and find out the final solution from many TRIZ solutions. By the usage, advantage of TRIZ is illuminated.
