根据x射线无标定量相分析方法和相平衡原理,本文提出一种测定合金相边界的简易方法:在三元系三相平衡区内,只要配制三个试样,便可测出这三相平衡区的相边界,用这种方法对Co+CoAl+Co_3Sn_2三相区边界进行了测定。结果表明,这种方法是行之有效的。 According to the X-ray uncalibrated phase analysis method and the principle of phase equilibrium, a simple method for determining the phase boundary of the alloy is proposed. In the ternary three-phase equilibrium zone, as long as three samples are prepared, the three phases The boundary of the equilibrium zone is measured by this method. The boundaries of the Co + CoAl + Co_3Sn_2 three-phase zone are determined. The results show that this method is effective.
