通常所说的强度是指抗拉强度,琴丝的抗拉强度平均每平方毫米400公斤,但商品名称为“白雀”的间胫胺纤维比这还要高。然而,纤维不能制成结构件,人们希望的是,既具有高强度,又能制成板状或块状。能满足这种要求的,就是六十年代才问世的马氏体时效钢。现在,这种钢已达到与琴丝相媲美的强度。目前已实用化的,强度已达200公斤级,正在试制的甚至有达400公斤级。马氏体时效钢是以铁为基体,含有镍、钴、钼、钛、铝的合金钢,它是应飞机、火
The so-called strength refers to the tensile strength, the tensile strength of the strings average 400 kg / mm 2, but the trade name of “white bird” is higher than the THA fibers. However, fibers can not be made into structural parts, and it is desirable that they be both high-strength and plate-like or massive. To meet this requirement, it is the maraging steel that appeared in the 1960s. Now, this steel has reached the strength comparable with the piano wire. Has been practical, strength has reached 200 kg class, is trial even up to 400 kg class. Martensitic aging steel is based on iron, containing nickel, cobalt, molybdenum, titanium, aluminum alloy steel, it is the aircraft, fire
