Reticulated mesh samples of Co-29Cr-6Mo alloy and Ni-21Cr-9Mo-4Nb alloy (625) and stochastic foam samples of Co-29Cr-6Mo alloy fabricated by electron beam melting were characterized by optical metallography, and the dynamic stiffness (Young's modulus) was measured by resonant frequency analysis. The relative stiffness (E/E) versus relative density (ρ/ρ) plotted on a log-log basis resulted in a fitted straight line with a slope n ≅ 2, consistent with that for ideal open cellular materials.
通过光学金相法对电子束熔炼制备的Co-29Cr-6Mo合金和Ni-21Cr-9Mo-4Nb合金（625）的网状网格样品以及Co-29Cr-6Mo合金的随机泡沫样品进行了表征，并通过共振频率分析测量了动态刚度（杨氏模量）。在对数-对数坐标系上绘制的相对刚度（E/E）与相对密度（ρ/ρ）关系图得到了一条斜率n≅2的拟合直线，这与理想开孔泡沫材料的情况一致。
