一种新型具有类似于塑料特性的钢即将投入批量生产。这种超塑性钢当被加热到760℃时,可以延伸到自身长度的十倍而不断裂,而大部分钢在此温度下只能延伸到自身长度的二倍。它的研制始于1988年,由Lawrence Livermore National Laboratory承担。这种超塑性钢的应用可以大大降低零件的机械加工。同时又具有特别高的含碳量,但它并不象其它淬硬钢那样脆,而是既坚硬又有很高的可塑性。这种材料可以承担具有各种复杂形状
A new type of steel with similar plastic properties is about to go into mass production. This superplastic steel, when heated to 760 ° C, can extend ten times its own length without breaking, whereas most steels can only extend twice their length at this temperature. Its development started in 1988 and was undertaken by Lawrence Livermore National Laboratory. This superplastic steel application can greatly reduce the machining of parts. At the same time it has a particularly high carbon content, but it is not as brittle as other hardened steels, but rather hard and highly ductile. This material can take on a variety of complex shapes
