The influence of heat treatment of dental alloys at several temperatures on the phases present in the alloy and the creep of the resulting amalgam as well as the correlation between phase changes and the creep was investigated. A dependence of the creep on the temperature of the heat treatment of the alloy was established. Substantial phase changes were observed after the different heat treatments. No correlation was detected between the creep rate and the changes in phases present in the dental alloys. A thermodynamically oriented explanation of the relation between the creep of the amalgam and the state of (non-) equilibrium of the corresponding amalgam alloy was proposed and discussed.
研究了牙科合金在几个温度下进行热处理对合金中存在的相、所得汞合金蠕变的影响以及相变与蠕变之间的相关性。确定了蠕变对合金热处理温度的依赖性。在不同热处理后观察到大量的相变。未检测到牙科合金中蠕变速率与相变化之间的相关性。提出并讨论了对汞合金蠕变与相应汞合金状态（非）平衡之间关系的热力学导向解释。
