摘要
综述了塑性加工技术的当前进展。分别介绍了薄坯铸轧、高强度钢板冷冲压、镁合金板材热态成形、内高压成形、单点数控增量成形、薄板热冲压-淬火、多点三明治成形及多尺度数值模拟等塑性加工新技术的特点及应用情况，如通过边凝固边轧制目前可得到约1～3mm厚的铸轧坯，可大幅度降低后续轧板的变形量与能耗，新研发的强度超过1000MPa的高强度钢的延伸率已可达60％。指出了塑性加工领域未来的发展趋势。
The new technologies of plastical forming were introduced, and they were continuous casting--rolling thin billet,cold stamping of high strength steel sheet, hot sheet forming of magnesi um alloy, tube high pressure hydro--forming, single numerical incremental forming, sheet hot stamping- qunching, multipoint sandwich forming and multi--scale numerical simulation, their characteristics and application. By casting --rolling the billet thickness with 1-3mm can be reached, so now the deformation and energy consummation can be reduced greatly for subsequent sheet rolling. The strength of newly developed high strength steels exceeds 1000MPa, simultaneously the elongation can be reached 60%. The developing tendency of plastical forming is analyzed separately.
