摘要: 钒微合金化锻造钢在现代汽车和卡车的动力传动系统和底盘的一些关键汽车构件中解决了轻量化、高性能和低成本的问题,在欧洲、日本和北美洲等汽车工业发达地区被广泛采用,并在新型汽车设计中起着重要作用,以满足在车身重量和排放指标方面越来越苛刻的要求。发展中国家和地区也将该项技术作为发展本土汽车产业、寻求更好工程解决方案的一项重要举措。这些锻造钢中的绝大多数采用中碳钢生产,添加了少量钒,在控制冷却铁素体-珠光体微观结构上提供大量的析出强化。从钒微合金化锻钢生产技术的发展历程、冶金原理、锻钢的性能特点及典型应用等方面进行了介绍。Abstract: Vanadium microalloyed steel forgings provide lightweight,high performance and cost effective solutions for many critical automotive components in the drivetrain and chassis of modern cars and trucks.These high strength steel forgings are already widely used in regions with developed automotive industries such as Europe,Japan and North America,and they play an important role in new vehicle designs required to meet increasingly stringent weight and emission targets.Developing countries and regions will also present a significant opportunity for adoption of this technology as indigenous automotive production expands and the best engineering solutions are applied.The majority of these forgings are produced from medium carbon steels with small additions of vanadium to provide substantial precipitation strengthening of the controlled cooled ferrite-pearlite microstructure.The aim of this paper is to provide an introduction to the essential aspects of this important technology by providing an overview of the historical development,basic metallurgy,processing,properties and typical applications.
