The equiatomic TiNbZrTaHf alloy was successfully rolled at room temperature with the reduction of ~ 85%. The microstructure and tensile properties were investigated after cold working and annealing. It was determined that the recrystallization temperature of the TiNbZrTaHf alloy between 850 and 900 ℃. Complete recrystallization and normal grain growth occurred, the high stability of single phase was maintained after annealing at 1000, 1200, and 1400 ℃. But the precipitated phase appeared after long term annealing, as seen after 500 h at 1000 ℃. After cold working, the tensile strength and the elongation of TiNbZrTaHf were 1137 MPa and 25.1%, respectively. The annealed alloy has a high tensile strength (σ_(b )= 863 MPa) and ductility (ε_(e )= 28.5%). Moreover, the oxidation of TiNbZrTaHf alloy at elevated temperatures has a significant impact on its mechanical properties. The poor oxidation resistance of TiNbZrTaHf can accelerate tensile failure by inducing fractures at grain boundaries.

蜣螂优化算法是一种新型的群智能优化算法。蜣螂优化算法具有快速收敛和较强的寻优能力,但也存在初始种群分布不均匀、全局探索和局部开发能力不平衡、易陷入局部最优等缺陷,可能无法有效地搜索整个解空间,从而无法得到最优解。针对蜣螂算法的特点,提出一种多策略改进的蜣螂优化算法解决蜣螂算法存在的问题。首先在初始化种群中引入Cricle混沌映射增加粒子多样性,可以减少粒子寻优时间,进一步提升算法的收敛速度;其次在引入改进正余弦算法中融合柯西变异算法,扩大蜣螂算法的搜索范围,避免算法陷入局部最优;最后在蜣螂觅食阶段加入Levy飞行自适应策略,增加蜣螂的随机性,提高算法的全局探索能力。将改进后的算法与灰狼算法、白鲸优化算法在23个测试函数中进行有效性对比验证,其中包括16个多峰基准函数,7个单峰基准函数,其中多峰函数6个维数不固定、10个维数固定,结果表明,改进后的算法确实有更好的性能。
