The name ''булат'' is a Russian transliteration of the Persian word ''fulad'', meaning steel. This type of steel was used by the armies of the nomadic people who were struggling to develop their smithing techniques. Bulat steel was the main type of steel used for swords in the armies of Genghis Khan, the great emperor of the Mongolian Empire. The technique used in making wootz steel has been lost for centuries and the bulat steel used today makes use of a more recently developed technique. == History == The secret of bulat manufacturing was lost by the beginning of the 19th century. eventually managed to duplicate the qualities of that metal in 1838, when he completed ten years of study into the nature of Damascus steel swords. Bulat became popular in cannon manufacturing, until the Bessemer process was able to make the same quality steels for far less money. Anosov had entered the Saint Petersburg Mine Cadet School in 1810, where a Damascus steel sword was stored in a display case. He became enchanted with the sword, and was filled with stories of them slashing through their European counterparts. In November 1817 he was sent to the factories of Zlatoust mining region in the southern Urals, where he was soon promoted to the inspector of the "weapon decoration department". Here he again came into contact with Damascus steel of European origin (which was in fact pattern welded steel, and not at all similar), but quickly found that this steel was quite inferior to the original from the Middle East. Anosov had been working with various quenching techniques, and decided to attempt to duplicate Damascus steel with quenching. He eventually developed a methodology that greatly increased the hardness of his steels. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bulat steel」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
