Abstract

The aim of this work is to investigate the bonding properties of the ceramic dispersion-strengthened 316L (CDS-316L) composites with the reference 316L stainless steel (REF-316L) using a Gleeble 3800 physical simulator. In previous works, two different composites, REF-316L and 316L, with 1 wt% AlO composite (CDS-316L) have been prepared by spark plasma sintering (SPS). In the present work, these specimens were diffusion-bonded using the following parameters: a temperature range of 950-1000 °C and a uniaxial pressure of 20-30 MPa. It was observed that the deformation of the CDS-316L during the uniaxial bonding process was higher compared to the 316L steel rods. The addition of alumina particles increased the micro-hardness of the 316L steel. The samples were broken in the CDS-316L zones, not at the diffusion-bonded interfaces. No diffusion zones have been observed within the investigated magnification for all composites, where the interfaces between the different specimens were well defined.

摘要

本工作的目的是使用Gleeble 3800物理模拟器研究陶瓷弥散强化316L（CDS - 316L）复合材料与参考316L不锈钢（REF - 316L）的结合性能。在先前的工作中，通过放电等离子烧结（SPS）制备了两种不同的复合材料，即含1 wt% AlO的复合材料（CDS - 316L）以及REF - 316L和316L。在本工作中，使用以下参数对这些试样进行扩散连接：温度范围为950 - 1000 °C，单轴压力为20 - 30 MPa。观察到，在单轴连接过程中，CDS - 316L的变形比316L钢棒更高。氧化铝颗粒的添加提高了316L钢的显微硬度。样品在CDS - 316L区域断裂，而非在扩散连接界面处。在所有复合材料的研究放大倍数范围内均未观察到扩散区，不同试样之间的界面清晰可辨。
