介绍了国内外高强度钢筋的发展历史、生产技术进展和发展趋势.微合金化、余热处理、细晶化是发展高强度钢筋的有效途径.在微合金化钢筋方面,V-N钢筋具有明显的技术经济优势;通过利用廉价的氮元素,促进了V(C,N)的析出,显著提高了V的沉淀强化效果,可节约钒用量50%,达到了节约贵重合金资源、降低生产成本的目的.余热处理钢筋和细晶粒钢筋通过组织强化或利用超细晶技术,在碳素钢和20MnSi钢的基础上获得了400MPa的Ⅲ级钢筋和500MPa的Ⅳ级钢筋,减少了合金的消耗,节约了资源.为了提高建筑物安全性,国外开发了屈服强度685~980MPa级的超高强度抗震钢筋.在耐腐蚀钢筋领域,开发了高氮不锈钢钢筋,满足建筑物长寿命的要求.
