| 图1 金属材料的零热膨胀：来源于晶格振动对体积正的贡献(ΔV2)与磁体积效应、马氏体相变或价态转变对体积负的贡献(ΔV1)相互抵消的结果 |
| Fig.1 Zero thermal expansion (ZTE) of metallic materials, originates from the mutual cancellation between the positive contribution to volume (ΔV2) from lattice vibrations and the negative contributions to volume (ΔV1) from magnetovolume efect, martensitic phase transitions, or valence state changes (TC—Curie temperature) |
