On the Production of the bronze Weapons

The knife moves simple and easy training, became civilians weapon, people of Liandao is the most, but most are mediocre. Knife and bronze sword, naturally somewhat more fragile temperament. The quality of the knife bronze sword and knife bronze sword collection tool is a very beautiful combination of contradictions, constantly challenge the limits of human wisdom, luck, materials and processes but is not a mystery. Consequently, the bronze were squeezed out from the daily life step by step. Good knife steel on hard, but after the heat treatment of steel toughness and hardness of the blade. Blade if the knife blade hard, allow the blade to absorb the energy Kandao things, so the blade is very easy to break or be turned. The carbon content of the steel is not as simple as the higher the better. Steel as a knife bronze sword, there are two basic properties.
First, hardness, first, toughness, hardness is the knife to cut how hard things, toughness is a material of much energy impact without breaking ability. Unfortunately, these two attributes are mutually exclusive to a certain extent, the higher the carbon content of steel inside, the higher the hardness of the build out of the more sharp knife, but also more brittle and are likely to encounter the hard stuff The collapse of the mouth; low carbon content of wrought iron, the toughness is high, the build out of the knife is not easy to collapse, can be bent or even to the extent that it will not break, but no hardness, cutting, not the hard stuff. The bronze weapons in the tomb of Shang in Dayangzhou, Xingang can be cited as the epitome of mainstream weapons in the Pre-Qin era. So, really good knife must be managed to the advantage of the integration of high-carbon steel and wrought iron. In ancient times, the best way is to use folded forged steel and wrought iron layer a layer of fine to play together, and the method of carburizing, so break out the knife both sharp high-carbon steel, and cooked The toughness of the iron.
This process to play out the knife bronze sword in ancient times is fine, fine, although this process is invented in China, but then Iran (ancient Persia) side of the forging process, the best, it is also known as the Damascus steel; folding forged out of steel, the surface will have layers of texture, very beautiful, it is also a pattern-welded steel. On the whole, the bronze in Sui and Tang Dynasties were mainly all kinds of bronze mirrors.  (Now these processes became extinct, some so-called master system out of something, mostly industrial pattern-welded steel, as well as torches and pickling the sensational things) the blade to maintain course and hardness relationship, because of the hardness itself is a knife part of. Knife cutting tools sharp is it a primary manifestation. But the more sharp to keep the lower, more easily damaged. Because the more sharp the edge is thinner.
 At the same time the higher the hardness the more likely to say nothing of the mouth and fracture, because the brittle! After it is damaged because of high hardness, but not easy to repair, too many factors that lead to the knife will blunt, understand? In brief, Han dynasty can be called the last hint of sun of the chinese bronze. This is why the hardness of steel to handle the higher should the segmented heat treatment or folder steel process. Pursuit of the balance of hardness and toughness! So-called good retention is appropriate to open the front angle, polishing and suitable for steel and hardness processing! Rather than simply say that the higher the hardness to maintain, the better! In fact the higher the hardness if the blade to open the thin die faster and more ugly. so you will find the pursuit of a lot of rough Yong tough hardness of the knife, body and edge are thick to keep very good.
