摘要

在发表于《Acta Mater.61 (2013) 294-309》一文中，Kamimura 等人根据实验数据，采用位错 "kink-pair "理论估算了各种陶瓷和半导体的 Peierls 应力。本文表明，他们计算出的 Peierls 应力值是不正确的，对于大多数材料来说，都比校正值低一个数量级。此外，我们还评估了 Kamimura 等人采用的 Peierls 应力估算方法的有效性。

Comments on “Experimental evaluation of the Peierls stresses in a variety of crystals and their relation to the crystal structure”

In a published paper, Acta Mater. 61 (2013) 294–309, Kamimura et al. estimated the Peierls stress of various ceramics and semiconductors based on experimental data by using a dislocation kink-pair theory. This paper shows that their calculated values of Peierls stress are incorrect, being one order of magnitude lower than the corrected values for most materials. Additionally, we assess the validity of the method for estimating the Peierls stress employed Kamimura et al.

期刊介绍： Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
