Hardness and shear band evolution in bulk metallic glasses after plastic deformation and annealing

Strain-induced hardening and annealing-induced softening are typical in crystalline metals. Bulk metallic glasses (BMG) exhibit the opposite behavior, namely, strain-induced softening and annealing-induced hardening. In addition, reversible softening–hardening–softening occurs in a BMG subjected to a three-step deformation–annealing–deformation process. The hardness changes after deformation and annealing can be correlated with the shear band patterns around/underneath Vickers indents. Shear bands produced during indentation of as-cast BMG are semicircular and radial, consistent with the stress distribution beneath the indenter. In contrast, the shear bands in the pre-strained BMG are irregular and convoluted, and appear to be a mixture of the shear bands produced during the prior compression and those in the as-cast BMG. After annealing, the shear bands tend to recover their semicircular and radial shapes consistent with the annealing-induced hardening.     

退火温度对铝青铜微观组织及硬度的影响

利用光学显微镜、扫描电镜、XRD和硬度计等分析了Cu-Al-Ni合金在冷轧与退火过程中微观组织结构及硬度的变化规律,研究了合金在不同退火温度条件下的软化行为。结果表明,当采用950 ℃保温淬火工艺后,Cu-Al-Ni合金主要由面心立方结构的α相与体心立方结构的β相组成,分布于晶界处的β相对合金硬度的影响作用小。由于位错强化作用的显著增强,合金在冷轧后硬度明显升高,达到270 HV0.5。冷轧态Cu-Al-Ni合金在400 ℃以上温度退火后会发生明显软化现象,软化的主要原因是再结晶反应所引起的位错密度下降。Cu-Al-Ni合金的再结晶温度在300 ℃以上,高于纯铜的再结晶温度,这表明Ni、Al元素的添加有利于提高纯铜再结晶温度,并能改善其高温抗软化性能。

Age softening phenomenon and microscopic mechanism of Li−B alloy

The age softening phenomenon of the Li−B alloy was investigated by a series of tensile tests under various aging conditions. The results show that the tensile strength of the rolled Li−B alloy decreases with increasing aging time. Higher aging temperature accelerates the softening process, and leads to an early end of aging. A model was proposed to analyze the mechanism of the age softening. The vacancy annihilation is the control factor of age softening. The strength−temperature relationship was estimated by the newly proposed model and a standard heat treatment, annealing at 150 °C for 1 h, was designed to eliminate the age softening of rolled Li−B alloy.

Effect of Cold-rolling on Mechanical Properties and Microstructure of an Al-12%Si-0.2%Mg Alloy

Effect of multi-pass cold-rolling on the mechanical properties and microstructure of a near-eutectic Al-12%Si-0.2%Mg casting alloy was investigated. Optical microscopy, SEM, and TEM were employed to resolve the as-rolled microstructure, and the microstructure of samples after aging treatment. It has been found that Brinell hardness increases considerably with rolling reduction ratio; and further annealing leads to a remarkable drop in hardness. Two mechanisms, namely precipitation hardening and recovery softening, were found to develop simultaneously in the subsequent aging treatment following cold rolling. In contrast, recovery softening dominated the aging of cold-rolled specimen with prior intermediate annealing. Tensile properties were also performed to measure the effect of cold rolling and subsequent aging treatment.
