概述了hcp金属的力学性能与变形行为.重点总结了Ti的滑移和孪生变形机理,报道了Ti的疲劳研究新结果.指出,应力轴位向是决定hcp金属变形行为的一个重要因素.理论预测和实验分析均表明,在hcp金属中,Ti与Zr不但具有高的强度,而且具有良好的塑性.
Mechanical properties and deformation mechanisms of hop metals espeCially the slip andtwinning behavior in Ti are summarized. sume new progress in fatigue study on Ti is rePOrted. Theorientation dependence of slip and twinning is emphasized. It is indicat
