However, their microstructural characteristics, particularly those of precipitates, remain poorly understood. This has hindered the establishment of structure-property relationship in these alloys. Here, we report the morphology, crystal structure and composition of the precipitates in the Al0.3CoCrCu0.5FeNi high-entropy alloy. Two types of precipitates were identified, namely the plate-like and the spherical precipitates. Their formation sequence and mechanism during the cooling process are discussed based on thermodynamics.}, journal={INTERMETALLICS}, author={Tsai, Ming-Hung and Yuan, Hao and Cheng, Guangming and Xu, Weizong and Tsai, Kun-Yo and Tsai, Che-Wei and Jian, Weiwei W. and Juan, Chien-Chang and Shen, Wan-Jui and Chuang, Ming-Hao and et al.}, year={2013}, month={Jan}, pages={329–336} } @article{tsai_yuan_cheng_xu_jian_chuang_juan_yeh_lin_zhu_et al._2013, title={Significant hardening due to the formation of a sigma phase matrix in a high entropy alloy}, volume={33}, ISSN={["1879-0216"]}, DOI={10.1016/j.intermet.2012.09.022}, abstractNote={The hardening in Al0.3CrFe1.5MnNi0.5 high-entropy alloy not only nearly triples the hardness of the alloy, but also shows a quick hardening response and the absence of overaging. However, the crystal structure, morphology, and composition of the hardening phase have not yet been confirmed. Here, such information regarding the hardening phase is investigated. It was found that the hardening phase is a Cr–Mn–Fe ternary sigma phase. Unlike in conventional engineering alloys, the sigma phase is not precipitated from the matrix, instead, the whole BCC matrix transforms to sigma phase almost without changing its composition. Therefore, the hardening phenomenon is not a precipitation hardening reaction as suggested before.}, journal={INTERMETALLICS}, author={Tsai, Ming-Hung and Yuan, Hao and Cheng, Guangming and Xu, Weizong and Jian, Weiwei W. and Chuang, Ming-Hao and Juan, Chien-Chang and Yeh, An-Chou and Lin, Su-Jien and Zhu, Yuntian and et al.}, year={2013}, month={Feb}, pages={81–86} } @article{hsieh_tsai_shen_yeh_2013, title={Structure and properties of two Al-Cr-Nb-Si-Ti high-entropy nitride coatings}, volume={221}, journal={Surface & Coatings Technology}, author={Hsieh, M.
