本文叙述一种传导带材成形样品的相氏模量和内耗的试验装置,可以以高于0.1%的相对精度测出相应温度下的杨氏模量。该装置还能测量通常所见整个范围的内耗(0.2≥tanδ≥2×10~(-6),tanδ是对数衰减,。为了测量金属玻璃体样品中的声学特性,需要用功来激励。金属玻璃相对于玻璃体的离子或聚合物配对体而言,它的结构简单是特别有意义的。从而使金属玻璃成为液态试验理论的理想材料。用“急冷”法和其它高
This article describes a test device for measuring the relative bulk and internal friction of strip-shaped specimens. The Young’s modulus at the corresponding temperature can be measured with a relative accuracy of more than 0.1%. The device also measures the internal friction (0.2 ≧ tanδ ≧ 2 × 10 -6) tanδ, which is logarithmically decaying, as usual. In order to measure the acoustic properties in metallic vitreous samples, work is required to energize the metallic glass Its simple structure is of particular interest relative to glass ionomer or polymer counterparts, thus making it an ideal material for liquid experimental theory. The “quench” method and other high
