Abstract
Creep is a time dependent, temperature-sensitive mechanical response of a material in the form of continuous deformation under constant load or stress. To study the creep properties of a given material, the load/stress and temperature must be controlled while measuring strain over time. The present study describes how a spark plasma sintering (SPS) apparatus can be used as a precise tool for measuring compressive creep of materials. Several examples for using the SPS apparatus for high-temperature compressive creep studies of metals and ceramics under a constant load are discussed. Experimental results are in a good agreement with data reported in literature, which verifies that the SPS apparatus can serve as a tool for measuring compressive creep strain of materials.
Highlights
Creep is the continuous deformation of a material subjected to a constant load or stress, often lower than its yield strength
ThisMoreover, is important for spark plasma sintering (SPS), that because ability to apply antoelectric current sintering to the sample makes it possible materials to investigate to it could be directly connected the enhanced behavior of conducting someInextent electro-plastic effects in conductive high temperature deformation the present study, we describe in detail thematerials use of anduring
Since the SPS apparatus typically only allows to apply a constant load, the actual stress on the sample continuously decreases during the test as the sample cross-section expands with increasing strain (Figure 5)
Summary
Creep is the continuous deformation of a material subjected to a constant load or stress, often lower than its yield strength. To track the densification progress, the SPS apparatus is equipped[9,10] This combination possible to achieve excellent sintering every capabilities many metallic, a strain gauge and makes built initLVDT. It was that the apparatus could be used as an worthy to notecreep that SPS creep test results havesuggested already shown goodSPS agreement with previously reported accurate creepby testing tool [12].testing Such capabilities already been demonstrated for both ceramics data obtained conventional methods forhave the same materials at similar temperature/pressure [12,13]. It has been proposed that the SPS apparatus’ ability to apply an electric agreement with previously obtainedtobysome conventional testing methods forconductive the same current to the sample makes itreported possible data to investigate extent electro-plastic effects in materials during at similar ranges [12,13,14,15]. SPS apparatus for creep investigation of metals and ceramics, highlight the advantages and disadvantages of this method, and provide prominent experimental examples of creep tests performed by an SPS apparatus applied as a creep testing device
