对MgAl2O4尖晶石进行了从室温到400 ℃的微柱压缩试验。尖晶石在200 ℃及以上的温度下塑性变形，没有围压。测量的屈服应力与其他地方获得的压缩较大的晶体在高围压下，这表明微柱压缩有可能是一个有用的技术研究脆性材料的塑性流动。(c)2009 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Micropillar compression tests were carried out on MgAl2O4 spinel from room temperature to 400 degrees C. The spinel deformed plastically at 200 degrees C and above without a confining pressure. The yield stresses measured were consistent with those obtained elsewhere by compressing larger crystals under a high confining pressure, suggesting that micropillar compression has the potential to be a useful technique for studying plastic flow in brittle materials.
