看完LZ叙述真是不知所云!玩什么样的刀,看你的诉求到底是什么。到底追寻一个什么样的目的。搞明白了吗?
所谓的个性爱好就在于此。
若追求材料的性能你说的这些钢材不过是铁基金属,非铁基金属性能远超 ...
请您在时间允许的情况下仔细阅读我的帖子和所有回复。
如果您读过我的帖子,尽管我思路放荡不羁,用词狂妄,但如果您仔细看过是可以“知所云”的。
首先我在帖子中阐明了我对玉钢文化传承的尊重。其次我以个人观点否定并质疑了玉钢的传奇、神化性能。最后以个人观点给刀匠和投资商提了个发展中国文化品牌的建议。
“玩什么样的刀,看你的诉求到底是什么。到底追寻一个什么样的目的。搞明白了吗?”在我的文章中阐述很清楚。在这里在简明重审一下:追求性能,则在力所能及的情况下选用现代科技产物。追求武士道文化底蕴,日本玉钢是首先。
“若追求材料的性能你说的这些钢材不过是铁基金属,非铁基金属性能远超你所列举那些钢材。
刀是一个综合载体割裂开单拿任何一个分类出来以点带面都不恰当”
-------追求性能,永无止境! 在力所能及的情况下选用性能更优越的现代科技产物。特指了l6和s5只是举个例子。没有否定非铁基金属的应用。如果试验条件和资金允许的情况下能够研发新型更高强度、更高韧性、更高屈服强度的材料,我提您和中国冶金的未来感到高兴(心里话)。美国的大学网站上可以找到不少关于Quantum Blacksmiths的论文,25美金信用卡就能买到。查一下诺贝尔化学奖获得者John Pople 和 Walter Kohn的论文.
还有关于amorphous 钢材。如果有兴趣、时间、精力和足够的理论知识基础可以买些论文读一下。即便不懂也增长些知识。这是个简单介绍:
“Metallic materials in use for several millennia were all crystalline with a periodic arrangement of atoms. But glass, which has been in use for a similar period, was noncrystalline with a random arrangement of atoms. In a serendipitous discovery in 1960 Pol Duwez, California Institute of Technology, USA quenched a gold-silicon alloy from the liquid state at a spectacular cooling rate of a million Kelvin per second and found that it had solidified as a metallic glass. This was indeed a new class of materials. Soon scientists discovered iron-boron metallic glasses. However, all these glasses were only a few microns thick because of the high cooling rate required. This changed dramatically in 1988, when Akihisa Inoue, a successor at Tohoku University to Korato Honda, found a way of lowering the cooling rate so that centimeter thick bulk artefacts can be produced. Inoue realised the importance of having an alloy made of as many components as possible. In a fashion reminiscent of Faraday, Breant and Anossoff he experimented with a large number of systems and found very many bulk metallic glasses. This indeed heralded a revolution. There was keen interest to develop iron based bulk metallic glasses. In 2004 Joe Poon, Gary Shiflet and Vidyabharathi Ponnambalam, University of Virginia, USA have reported the preparation of Fe-Mn-Cr-Mo- (Y, Ln) -C-B glass with a thickness of 7mm. This is a true witch’s brew containing as many as eight elements. This glass was three times stronger than conventional steel and had superior corrosion resistance. It can be formed easily in the supercooled liquid state, very similar to superplastic crystalline materials. Among the many applications lighter but harder armour peiercing projectiles are envisaged- a modern day Damascus blade! One can expect with eager anticipation further developments. Controlled crystallisation can lead to nanocomposites with an enhancement of many desirable properties and perhaps with a damascene structure!”

追求性能就是永无止境。我在大学时对冶金、和金相学研究非常感兴趣,并对刀剑制造十分向往。但是为了贪图蝇头小利干了别的行业而放弃了理想追求。现在后悔莫及。
至于“说个题外话若单论现代钢材的冶炼技术日本是顶尖级别的。难道日本传统制刀匠一无所知吗?
那个网上流传最广的用原始土炉炼钢的老者是日本日立特种炼钢所专门研究冶炼工艺的高级工程师,为什么会痴心的用这种方式呢?”-----这体现的是一种文化传承的追求境界,并不代表性能的追求。对这种精神我一向是尊重的。您自己提到的“诉求”,如果“诉求”完全是性能,个人认为玉钢是“诉求”错了。在自己经济状况允许的情况下,有多种性能更好的材料可以取代玉钢。
网络上传奇般的“刀切铅心的子弹”完全属于正常现象。这是个物理学的问题,高速飞行中子弹在碰撞时的动能无法完全传递给刀身,这是点密度、点强度和动能传递的相对变量关系造成的。和膛线设计也有一定关系。用不着理论和公式计算,paul southern先生的200美金便宜货一样能多次切割9mm手枪弹。
对于学习和探讨问题是应该提倡言论自由的。我言辞多有“不知天高地厚”“愤青”之处,这是学习过程中无知的正常体现,如有得罪还请前辈们海涵。但在下的所谓“愤青”还没有达到盲目的地步,对于日本人的先进技术我一向尊重并主动学习。如果不把自己的无知体现出来就没法得到教训和批评,更无法进步。我之所以“大放厥词”本来就是抱着接受批评接受教育学习的心态,将个人看法及观点毫无演示的统统倒出,绝对没有对日本文化传承者、爱好者带有半点不敬之意。在对于我在中国刀剑文化何去何从上提的建议,只是对中国刀剑发展业的跟人观点。如有对商人及刀匠的冒犯之处,在下在此罚酒三杯深表歉意。
