I have been engaged in the research of metal materials, and I am familiar with their preparation, properties and applications. In connection with those things in daily life, I feel more and more that many behaviors of metal materials and many things in life are for the same reason. Let's talk about the relationship between material behavior and marriage, which is the easiest to understand. Originally, these are two unrelated issues, and you can gradually understand the connection between them. Talk about materials and love from the beginning. Take steel materials as an example. Pure iron is made of iron ore ironmaking in blast furnace, purified by various electric furnaces, gradually growing up like a newborn, and then studied by professional matchmakers of materials scientists or metallurgists. The process of matching is like falling in love. Suitability is as important as like-mindedness. Only by melting in high-temperature love can a stable steel family be formed. For example, pure iron and simple carbon are married to form pairs of different types of carbon steel families, which is the most common combination in the steel material family. Although the share of carbon in the family is very small, carbon has penetrated into the iron cell, and women are the masters and have real power, but high carbon steel is hard but fragile. In order to attract more people's attention and improve the popularity of the steel family, there must be a star, the name is very important, the scandal is also very important, and the hype is even more important. Therefore, steel also began to speculate on polygamy. The intervention of three small and four small, each shine brilliantly, forming a group of representative steel stars, heroic heat-resistant steel, eye-catching stainless steel, industry pacesetter weather-resistant steel and so on. If you get married, you will get divorced. The fracture of matter, like the fracture of marriage, is a problem of cracking. The cause of material fracture may come from tension or pressure, and cracks will gradually expand from surface or internal defects and fracture. Materials with good toughness will produce plastic deformation and then slowly fracture, and brittle materials will fracture directly. The reason for the breakdown of marriage comes from the temptation of family and the outside world (lover, money, power, etc.). ) or stress (parents, work, etc. ). From some trivial matters or old accounts in family life, the relationship between husband and wife has gradually deteriorated. The speed of breaking up is based on the relationship between husband and wife, and the relationship has been delayed for many years before divorce, and there are also many direct divorces with poor foundation. If there is no such pressure and inducement, the material will return to its original state and the husband and wife will get back together. Even if we quarrel occasionally, it is a quarrel at the end of the bed. You can also anneal the marriage through the second honeymoon holiday to alleviate the crisis. Another case is to prevent the material from breaking. For example, you have seen a crack in the windshield of a car. The treatment is to drill a hole in the crack and expand the crack tip into a hole, thus ensuring that the crack will not continue to expand. It is also useful for marriages with potential crisis. For example, at this time, one of the husband and wife suddenly became seriously ill. Under great circumstances, the husband and wife will get together again and work together to overcome the disease. This serious illness is like a hole drilled in the glass, and the enlarged contradiction covers up the initial small contradiction. These materials will eventually break and they can be welded together if they want to be used again. However, due to the existence of weld and heat affected zone, the performance is always worse than before. For marriage, divorce is not appropriate, children need a complete family, and the most convenient way to live together is to remarry, but after second time around, cracks always exist. In other words, if the material is broken, find another piece of other metal and weld it together. If it is not properly matched, it will break again soon. In the same way, there are very few couples who can spark love halfway, which is definitely not as good as at the beginning. The most thorough solution to the material is remelting, which is melted at high temperature and forged into a brand-new material. For a broken marriage, if divorced couples can experience the tempering of love again, I believe their marriage will be rock solid. After talking about material and marriage, in fact, many behaviors of material are closely related to life, limited to space, in short. For example, the fatigue behavior of materials and people's fatigue, the corrosion resistance of materials and people's ability to resist temptation, the hardness of materials and people's ambition or backbone. People's quality is just like the performance of materials. Good material performance is obtained after many times of cold and hot processing. One tiny inclusion may be fatal, but we are not. We hope to constantly purify our hearts and be invincible!
