Thermophysical properties of liquid metal alloys play a crucial role in the variety of processes. Present work reports experimental investigations of two new transformation induced plasticity (TRIP) steels. A classical maximum bubble pressure technique is successfully used to measure surface tension and density of the liquid TRIP‐steel samples in the temperatures range of 1500–1800 °C. Experiments are performed in two different measurement cells from TU Freiberg and Commissariat a l'Energie Atomique (CEA), Cadarache. Capillaries are made of zirconia partially stabilized with yttrium oxide, and the samples are molten in Al₂O₃ crucibles. Measurements are conducted under the argon atmosphere. Surface tension of the investigated samples rises up to 1700 °C and further remains the same. Density of the new steels obtained in this study is in good agreement with the previously reported values for Fe–Cr alloys with similar Cr content. Density of the alloy is estimated as 875 488–11 885 × T (±218.85 kg m⁻³) for a 15%Cr alloy and 796 042–06 897 × T (±199 kg m⁻³) for a 19%Cr alloy.

转变诱导塑性效应的Cr-Mn-Ni钢的表面张力和密度

液态金属合金的热物理性质在各种过程中都起着至关重要的作用。目前的工作报告了两种新型相变诱发塑性（TRIP）钢的实验研究。经典的最大气泡压力技术已成功用于在1500–1800°C的温度范围内测量液态TRIP钢样品的表面张力和密度。实验是在两个不同的测量单元中进行的，这些单元分别来自TU Freiberg和Cadarache能源委员会（CEA）。毛细管由氧化钇部分稳定的氧化锆制成，样品在Al ₂ O ₃中熔融坩埚。测量在氩气氛下进行。所研究样品的表面张力升高至1700°C，并保持不变。在这项研究中获得的新钢的密度与先前报道的具有相似Cr含量的Fe-Cr合金的值非常吻合。该合金的密度被估计为875 488-11 885×  Ť（±218.85公斤米^-3）对于15％Cr合金和796 042-06 897×  Ť（±199公斤米^-3），用于19％Cr合金。
